The ASA has purchased assistive listening devices (ALDs) for the benefit of meeting attendees who need them at technical sessions. Any attendee who will require an assistive listening device should advise the Society in advance of the meeting by writing to: Acoustical Society of America, Suite 1NO1, 2 Huntington Quadrangle, Melville, NY 11747-4502; Email:


The technical program includes 116 sessions, with 1091 papers scheduled for presentation during the meeting.

Session Chairs have been instructed to adhere strictly to the printed time schedule, both to be fair to all speakers and to permit attendees to schedule moving from one session to another to hear specific papers. If an author is not present to deliver a lecture-style paper, the Session Chairs have been instructed either to call for additional discussion of papers already given or to declare a short recess so that subsequent papers are not given ahead of the designated times.


The first character is a number indicating the day the session will be held, as follows:

1-Monday, 18 May
2-Tuesday, 19 May
3-Wednesday, 20 May
4-Thursday, 21 May
5-Friday, 22 May
6-Saturday, 23 May (for Speech Workshop abstracts only)

The second character is a lower case ''a'' for a.m., ''p'' for p.m. or "e" for evening corresponding to the time of day the session will take place. The third and fourth characters are capital letters indicating the primary Technical Committee that organized the session using the following abbreviations or codes:

AA - Architectural Acoustics
AB - Animal Bioacoustics
AO - Acoustical Oceanography
BB - Biomedical Ultrasound/Bioresponse to Vibration
EA - Engineering Acoustics
ED - Education in Acoustics
ID - Interdisciplinary
MU - Musical Acoustics
NS - Noise
PA - Physical Acoustics
PP - Psychological and Physiological Acoustics
SA - Structural Acoustics and Vibration
SC - Speech Communication
SP - Signal Processing in Acoustics
UW - Underwater Acoustics

In sessions where the same group is the primary organizer of more than one session scheduled in the same morning or afternoon, a fifth character, either lower-case ''a,'' or ''b" is used to distinguish the sessions. Each paper within a session is identified by a paper number following the session-designating characters, in conventional manner. As hypothetical examples: paper 2pEA3 would be the third paper in a session on Tuesday afternoon organized by the Engineering Acoustics Technical Committee; 3pSAb5 would be the fifth paper in the second of two sessions on Wednesday afternoon sponsored by the Structural Acoustics and Vibration Technical Committee.

Note that technical sessions are listed both in the calendar and the body of the program in the numerical and alphabetical order of the session designations rather than the order of their starting times. For example, session 3aAA would be listed ahead of session 3aAO even if the latter session began earlier in the same morning.


A distinguished lecture titled "A Residual-Potential Boundary for Time-Domain Problems in Computational Acoustics" will be presented by Thomas L. Geers, University of Colorado, in session 4aSAa, on Thursday, 21 May, at 9:00 a.m. in the Forum Room.


A Hot Topics session will be held in Session 3pID on Wednesday, 20 May, at 1:00 p.m. in the Executive Salon II/III and will end before the start of the Plenary Session.

Outdoor environmental noise is becoming more prominent in the United States as the population and infrastructure continues to grow. The prediction or estimation of outdoor noise levels is a technically challenging area, since there are a number of uncertainties regarding how to model the sound source, the propagation path, and many other factors that influence the results such as temperature, wind, and terrain to name a few. Outdoor noise estimation is, however, required with many projects, including construction of wind farms and power plants. This short course will present the current state of knowledge on predicting outdoor noise, and discuss the standards and uncertainties that exist in this area. Examples from a variety of practical applications will be explored. Additionally, an introduction to noise mapping and soundscapes will be provided. Although this methodology is not implemented broadly in the United States, the European Directive 2002/49/EC on environmental noise requires members of the European Union to evaluate the environmental noise within their territories and to illustrate it using noise maps. The course will delve into successes of this endeavor as well as lessons learned so far.


To introduce the methodologies, uncertainties, and standards regarding outdoor noise estimation. A number of environmental noise applications, ranging from prediction of noise from wind farms to noise and psychoacoustics mapping will also be presented.


The short course will be taught by a team of instructors who cover a wide range of expertise in outdoor noise estimation and mapping. Ken Kaliski is Director of Environmental Services at Resource Systems Group, White River Junction, VT. Mr. Kaliski is a Professional Engineer and INCE Board Certified, with experience in community noise mapping and modeling such sources as wind farms, quarries, and highways. Robert Putnam is a Senior Acoustical Engineer at Siemens Energy Systems, Orlando, FL. Mr. Putnam has over 40 years of experience in the design and prediction of power plant noise, currently serves as Chair of standards writing committees within ASTM and ASME, and has previously conducted tutorials on environmental noise for ASA and INCE. Dr. Brigitte Schulte-Fortkamp is a Professor at the Technical University of Berlin, Germany, and Dr.-Ing. Klaus Genuit is with HEAD Acoustics in Germany, Both Dr. Schulte-Fortkamp and Dr. Genuit are Fellows of the ASA who have extensive experience on community noise evaluation, sound quality, and soundscapes.

There will be an informal "jam session" on Tuesday, 19 May, from 9:00 p.m. to 12:00 midnight in Bistro 921 (ground floor) at the Hilton. This open live music session is courtesy of ASA members. Anyone interested in participating should contact Tom LePage at


Information and a point of contact regarding child care will be provided on the ASA web site at a later date.


Spouses and other visitors are welcome at the Portland meeting. The registration fee for accompanying persons is $50.00 for pre-registration by 27 April and $75.00 at the meeting. A hospitality room for accompanying persons will be open at the Hilton from 8:00 a.m. to 10:30 a.m. each day throughout the meeting where information about activities in and around Portland will be provided.

Two tours for both attendees and accompanying persons will be offered during the Portland meeting: an evening walking brew-pub tour and a half-day Willamette Valley wine-tasting tour.

The brew-pub tour will be held on Wednesday, 20 May, starting at 6:30 p.m. and will consist of walking to three or four brewpubs in downtown Portland to sample their products. Tours of the brewing facilities and Q & A with brewery representatives may also be possible. A deposit of $10 will reserve a spot in the tour (space is limited) and will be used to partially offset costs of beverage purchases. Payment for the balance due will be required at the meeting.

The half-day wine-tasting tour will be held on Friday, 22 May, from about 12:00 noon to 6:00 p.m. and will consist of a personalized, van-based route visiting two to four wineries in the Oregon wine country of the Willamette Valley. There is an option to include lunch at one of the wineries. The cost depends on the number of participants but will be approximately $75 to $100 (depending on whether lunch at a winery will be part of the tour). Information on the tour company, Grape Escape, can be found at

Early deposits are needed to ensure the tours will run and to reserve space. Deposits ($10/person for the beer or $35/person for the wine tour) should be sent no later than 15 April to the ASA. To register, download the accompanying persons tour registration form and send it to ASA with payment of your deposit.

The tours will only be offered if there is sufficient interest; in the event of cancellation, deposits will be refunded. Questions on either of these tours can be sent to Note that the legal drinking age in Oregon is 21 and some establishments may not admit patrons below that age.

Portland is the most sustainable city in the United States. At this year's ASA meeting in Portland, many sustainable green elements have been implemented, including picking a green seal certified venue, Hilton Portland & Executive Tower; recycling and reusing meeting materials; and following the guideline of the Green Conference Initiative from the U.S. Environmental Protection Agency. While you travel to the beautiful city of Portland for the ASA meeting, you can help make sure that the meeting goes greener by doing the following:

Bring your own hardcopy of the meeting program that has been mailed to you; bring your own water container or coffee mug for reuse at the meeting; use public transportation (convenient light-rail service from the airport to the downtown meeting venue); visit the nearby Portland State University and take a campus self-guided sustainability tour

In an effort to offset the carbon footprint of the meeting in Portland, the ASA will contribute $2000 to a non-profit carbon offset provider which will compensate for some of the carbon emissions generated for the meeting. The local organizing committee will select the organization based on applicability of project types (energy, renewables, etc.) and alignment with ASA tenets. Attendees can contribute to minimizing their own carbon footprint by car pooling when possible, taking a train instead of driving, and using the light rail from the airport to the hotel.


Weather in May is perfect for enjoying the emerging blossoms in the City of Roses. Portland temperatures average between about 47 to 68 degrees (F) in May with an average rainfall of 2.06 inches. The majority of days, on average, range from clear to partly cloudy/cloudy. Recent observations and forecasts may be found on a number of different web pages (e.g.,

A. Preparation of Visual Aids

1. See the guidelines for computer projection below.
2. Allow at least one minute of your talk for each slide or other visual aid, e.g., no more than 12 slides for a 15-minute talk.
3. Minimize the number of lines of text and the number of curves shown on one visual aid. More than 12 lines of text or 5 curves are too many to be comprehended within one minute. Too little is better than too much.
4. On a transparency for overhead projection, all material should be within an 8x9-inch (20x23 cm) frame. Characters should be at least 0.2 inches (5 mm) high to be legible when projected; conventional 10- or 12-font characters are too small.
5. Make symbols no less than 1/3 the height of a capital letter. Break away any line that would otherwise pass through a character or symbol.
6. Black lines on clear background or white lines on black background are more legible than colored lines. Use color only if required to distinguish different curves or elements.
7. Video tapes must be in the standard VHS format. Videotapes not in the standard VHS format must be converted to this format by the individual presenter prior to the meeting.

B. Presentation

1. Organize your talk with introduction, body, and summary or conclusion. Include only facts or concepts that can be explained adequately in the allotted time. Rehearse talk so you can confidently deliver it in that time.
2. Session Chairs have been instructed to adhere to the time schedule and to stop your presentation if you run over.
3. An A/V preview room will be available for viewing computer presentations, transparencies or videotapes before your session starts.
4. Arrive early enough so that you can meet the session chair, load your computer presentation on to the computer provided, check your slides in the projector, and familiarize yourself with the microphone, slide controls, laser pointer, and other equipment.
5. Every time you display a visual aid the audience needs time to interpret it. Although you are familiar with the data, the audience may not be. Describe the abscissa, ordinate, units, and the legend for each curve. If the shape of a curve or some other feature is important, tell the audience what they should observe in order to grasp the point. They won't have time to figure it out for themselves.

A board approximately 8 ft. wide x 4 ft. high will be provided for the display of each poster paper. Supplies will be available for attaching the poster material to the display boards. Each board will be marked with the board location number. Note that the board location number may not correspond with the abstract number. Authors should furnish, as part of their poster presentation, a sign giving the abstract number, paper title and author(s) name, in lettering approximately 1-1/2 inch high. Free-hand lettering with a felt pen is entirely adequate.

A poster paper should be able to ''stand alone,'' that is, be understandable even if the author is not present to explain, discuss, and answer questions. This is highly desirable because the author may not be present for the entire time the poster papers are on display, and when the author is engaged in discussion with one person, others may want to study the display without interrupting an ongoing dialogue. To meet the ''stand alone'' criteria, it is suggested that authors consider the following elements for a poster. Each element can be arranged on one or more standard letter-size sheets. Where typing is needed, large font type is very effective. Careful hand lettering, at least 1/4 in. high, is also acceptable. Obviously, it may not be appropriate for any given paper to include all of the ''elements'' listed below. These are merely suggestions:

1. Objective, purpose, goal, etc.
2. Background information. Prior work.
3. Assumptions, etc.
4. Experimental arrangements, block diagram, sketch, photos, parameters.
5. Outline of the theoretical development.
6. Data, graphs, tables, etc.

Graphs and photographs should be a minimum of 8 x10 inches. Figure captions are essential. Avoid glossy paper.

Display objects, such as transducer elements or materials, demonstration tapes, etc., are excellent supplements to a poster.

Since the poster paper is not archival, feel free to bring incompletely reduced data for discussion

A PC computer with audio playback capability and projector will be provided in each meeting room on which all authors who plan to use computer projection should load their presentations. Authors should bring computer presentations on a CD or USB drive to load onto the provided computer and should arrive at the meeting rooms at least 30 minutes before the start of their sessions. Assistance in loading presentations onto the computers will be provided.

Note that only PC format will be supported so authors using Macs must save their presentations for projection in PC format. Also, authors who plan to play audio during their presentations should insure that their sound files are also saved on the CD or USB drive.

Presenters also have the option to connect their own laptops to the computer projector as was done at past ASA meetings. The following guidelines should be observed by speakers presenting Power Point or equivalent presentations at meetings of the Acoustical Society of America who plan to use their own computers in their presentations.

It is strongly recommended that overhead transparencies be brought to the session by speakers as backup.


It is essential that each speaker connect his/her own laptop to the computer projection system in the A/V preview room prior to session start time to verify that the presentation will work properly. Technical assistance is available in the A/V preview room at the meeting, but not in session rooms. Presenters whose computers fail to project for any reason will not be granted extra time.


1. Set your computer's screen resolution to 600 by 800 pixels or to the resolution indicated by the AV technical support. If it looks OK, it will probably look OK to your audience during your presentation.

2. Use all of the available screen area. If a page in portrait orientation is displayed in landscape orientation computer projection, the two sides of the projected image will be blank, effectively shrinking the text size. All documents/figures should be created in landscape orientation with very thin margins, thereby making maximum use of the (limited) resolution of the computer projector.

3. No more than 2 graphs/plots/figures should be included on a single slide. Use large lettering for axis labels and bold fonts for the numbers. Remember that graphics can be animated or quickly toggled among several options: comparisons between figures may be made temporally rather than spatially.

4. Avoid thin fonts, including fonts with thin elements (e.g., the horizontal bar of the "e" may be lost because it is less than one pixel wide at the low resolution of the computer projector, thereby registering as a "c"). If using a thin font, make it bold to widen the minimum line width. Avoid thin lines which may look fine when viewed on the high screen resolution setting but will fade or disappear when a low screen resolution is set.

5. Contrasts must be enhanced in computer-projected documents for good visibility. Use dark backgrounds with lighter (contrasting) lettering, rather than white backgrounds with dark lettering. Avoid busy backgrounds, and keep text and figures simple and large.

6. Avoid the use of red, especially on purple or green backgrounds. People with common color blindness will not see figures in red if they are backed by similar colors.

7. Avoid large borders and logos of institutions as these leave a reduced area for actual data and graphs. If such borders or logos are necessary, place them at the bottom of the slide so that your technical data appears at the top of the projected image.

8. Animations often run more slowly on laptops connected to computer video projectors than when not so connected. Test the effectiveness of your animations before your assigned presentation time on a similar projection system (e.g., in the A/V preview room). Avoid real-time calculations in favor of pre-calculation and saving of images.

9. If you will use your own laptop instead of the computer provided, a video switcher will be available. During the question and answer period of the previous speaker, connect your laptop to the video switcher. It is good protocol to initiate your slide show (e.g., run PowerPoint) immediately once connected, so the audience doesn't have to wait. When it is your turn to present, the session chair will press the button on the switcher corresponding to the appropriate number of the input to which you connected (indicated on the cord you plugged into your computer). If there are any problems, the session chair will endeavor to assist you, but it is your responsibility to ensure that the technical details have been worked out ahead of time.

10. During the presentation have your laptop running with main power instead of using battery power to insure that the laptop is running at full CPU speed. This will also guarantee that your laptop does not run out of power during your presentation.

Specific Hardware Configurations


Older Macs require a special adapter to connect the video output port to the standard 15-pin male DIN connector. Make sure you have one with you.

1. Hook everything up before powering anything on. (Connect the computer to the RGB input on the projector).

2. Turn the projector on and boot up the Macintosh. If this doesn't work immediately, you should make sure that your monitor resolution is set to 1024x768 for an XGA projector or at least 640x480 for an older VGA projector. (800x600 will most always work.). You should also make sure that your monitor controls are set to mirroring.

If it's an older powerbook, it may not have video mirroring, but something called simulscan, which is essentially the same.

Depending upon the vintage of your Mac, you may have to reboot once it is connected to the computer projector or switcher. Hint: you can reboot while connected to the computer projector in the A/V preview room in advance of your presentation, then put your computer to sleep. Macs thus booted will retain the memory of this connection when awakened from sleep. Alternatively, you can reboot while connected to the video switcher during the previous speaker's presentation, but it is safer to queue this up in advance of the session.

Depending upon the vintage of your system software, you may find that the default video mode is a side-by-side configuration of monitor windows (the test for this will be that you see no menus or cursor on your desktop; the cursor will slide from the projected image onto your laptop's screen as it is moved). Go to Control Panels, Monitors, configuration, and drag the larger window onto the smaller one. This produces a mirror-image of the projected image on your laptop's screen. Also depending upon your system software, either the Control Panels will automatically detect the video projector's resolution and frame rate, or you will have to set it manually. If it is not set at a commensurable resolution, the projector may not show an image. Experiment ahead of time with resolution and color depth settings in the A/V preview room (please don't waste valuable time fiddling with your Control Panel settings during your allotted session time).


Make sure your computer has the standard female 15-pin DE-15 video output connector. Some computers require an adaptor.

Once your computer is physically connected, you will need to toggle the video display on. Most PCs use either ALT-F5 or F6, as indicated by a little video monitor icon on the appropriate key. Some systems require more elaborate keystroke combinations to activate this feature. Verify your laptop's compatibility with the projector in the A/V preview room. Likewise, you may have to set your laptop's resolution and color depth via the monitor's Control Panel to match that of the projector, which settings you should verify prior to your session.


Most Linux laptops have a function key marked CRT/LCD or two symbols representing computer versus projector. Often that key toggles on and off the VGA output of the computer, but in some cases, doing so will cause the computer to crash. One fix for this is to boot up the BIOS and look for a field marked CRT/LCD (or similar). This field can be set to Both, in which case the signal to the laptop is always presented to the VGA output jack on the back of the computer. Once connected to a computer projector, the signal will appear automatically, without toggling the function key. Once you get it working, don't touch it and it should continue to work, even after reboot.
