Papers that address all aspects of the generation, propagation, and control of vehicle noise, as well as the effect of noise on structures and individuals, are being solicited. The program’s technical content will include theoretical, numerical, and experimental contributions that describe original research results and/or innovative design concepts. In addition, in-depth reviews and timely surveys will be considered.
Topics for the conference are listed under “Technical Session Topics.” Studies in other related areas, particularly the application of aerospace noise suppression technologies in other industries and papers pertaining to nonaerospace research with potential application to the aerospace industry, are encouraged.

Abstract Submittal Requirements
An extended abstract of at least 1000 words, with key figures and references to pertinent publications in the existing literature, is required. Authors must clearly identify in the abstract new or significant aspects of their work. Abstract reviewers will base recommendations for acceptance or rejection on: 1. Whether the abstract meets the requirements described above; 2. The relevance of the work; 3. The originality of the work; 4. Contributions to the field, i.e. whether it advances the current state of knowledge; 5. Whether significant results are presented to ensure timely completion of the paper.
Abstract Submittal Information
Abstract submissions for the conference will be accepted electronically through this Web site which will be open for abstract submittal through 27 October 2008. The electronic submission process is as follows:
- From the conference Call for Papers screen, identify the topic to which the prospective paper is best correlated, and click the “Select” link next to that topic.
- Verify the topic selection and click “Select” again, then verify the rules and regulations on the subsequent page.
- Answer the prompts to enter paper title, author information (including e-mail address), and A/V requirements.
- When this information is complete, authors will be prompted to upload the abstract in any one of five formats: MS Word, WordPerfect, Text, RTF, or PDF.
Authors having trouble submitting abstracts electronically should e-mail AIAA technical support at paper_tech_support@aiaa.org. Questions about the manual abstract submission or full draft manuscript themselves should be referred to the appropriate Technical Chair.
Authors will be notified of paper acceptance or rejection on or about 19 December 2008. Instructions for preparation of final manuscripts will be provided by AIAA for accepted papers only. Authors of accepted papers must provide a complete manuscript online to AIAA by 27 April 2009 for inclusion in the online proceedings and for the right to present at the conference. It is the responsibility of those authors whose papers or presentations are accepted to ensure that a representative attends the conference to present the paper. Sponsor and/or employer approval of each paper is the responsibility of the author(s), as is government review, if required. Authors should determine the extent of approval necessary early in the paper presentation process to preclude paper withdrawals or late submissions.

Student Paper Competition
Undergraduate and graduate students are encouraged to submit papers for consideration in the Aeroacoustics Student Paper Competition. Student papers should report on thesis work conducted by students in collaboration with faculty advisors. The student submitting a paper for consideration must be the primary author, and must have been a student at the time of the preceding Aeroacoustics Conference. Papers submitted by students must be presented by the primary author at the conference. The student author of the best paper will receive a monetary award and certificate during the conference. The best student paper award will be selected on the basis of the technical quality of the paper, including its presentation. Papers not received by the student paper submission deadline or not presented by the student at the conference will not qualify for the award. Interested students should submit abstracts electronically through this Web site following the abstract submittal process as specified in this Call For Papers. Please submit to the appropriate topic, and be sure to select the “Student Paper Submission” check box.
“No Paper, No Podium” Policy
If a written paper is not submitted by the final manuscript deadline, authors will not be permitted to present the paper at the conference Young Professionals Program Young professionals are encouraged to participate in the Young Professionals Presentation Program, which provides young professionals under the age of 35 with an opportunity to present their work at a national AIAA technical conference. This program integrates young engineers into the regular sessions and allows them to give presentations covering continuing and in-process design or research works, in addition to completed projects. The Young Professionals Presentation program allows for oral presentations only; manuscripts are not required. Abstracts must be submitted as specified in this Call For Papers. All submission deadlines and policies are according to those specified in this Call For Papers.
Warning – Technology Transfer Considerations
All authors are reminded that technology transfer guidelines have substantially extended the time required for review of abstracts and completed papers by government agencies. Internal (company) plus external (government) review can consume 16 weeks or more. Government review is the responsibility of the author. Authors should determine the extent of approval necessary early in the paper preparation process to preclude paper withdrawals and late submissions.
International Traffic in Arms Regulations (ITAR)
AIAA speakers and attendees are reminded that some topics discussed in the conference could be controlled by the International Traffic in Arms Regulations (ITAR). U.S. Nationals, which are U.S. Citizens and Green Card Holders, are responsible for ensuring that technical data they present in open sessions to non-U.S. Nationals in attendance or in conference proceedings are not export restricted by the ITAR. U.S. Nationals are likewise responsible for ensuring that they do not discuss ITAR export restricted information with non-U.S. Nationals in attendance.
