About the Conference
The AIAA/CEAS Aeroacoustics Conference has established itself as the premier international forum for the field of aeroacoustics. It offers scientists and engineers from industry, government and universities an exceptional opportunity to exchange knowledge and results of current studies and to discuss directions for future research. 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 solicited.
The program’s technical content will include theoretical, experimental, and numerical contributions that describe original research results and/or innovative design concepts including those related to recent advances in low-carbon aircraft architectures and urban air mobility vehicles. In addition, in-depth reviews and timely surveys will be considered. Topics identified for the conference are listed below. Papers in other related areas, including the application of aerospace noise suppression technologies in other industries, and non-aerospace research with potential application to the aerospace industry are encouraged.
Call for Papers and Announcement: ABSTRACT SUBMISSION IS NOW CLOSED
AIAA/CEAS Aeroacoustics Best Paper Award
Conference papers of superb technical quality, originality, and scholarly accuracy will be considered, alongside aeroacoustics papers in the 2023 SciTech Forum, for the 2023 AIAA/CEAS Aeroacoustics Best Paper Award.
Student Paper Award
Undergraduate and graduate students are encouraged to submit papers to the Aeroacoustics Student Paper Competition by selecting “Student Paper Competition” presentation type when uploading abstracts. Student papers should report on thesis-related work conducted in collaboration with faculty advisors. The primary author must have been a student in May 2021 and must present the paper. The award will be based on the technical quality of the paper and the clarity of the presentation. The winning student will receive a monetary award and certificate.

Special Session on Hybrid Anechoic Wind Tunnels
Session Scope: The Hybrid Anechoic Tunnel Workshop is a forum that brings together researchers interested in hybrid anechoic aeroacoustic wind tunnels and their application. A major goal is to develop common test cases to cross validate and characterize hybrid anechoic wind tunnels as well as provide data on canonical test cases to the broader aeroacoustics community. The purpose of the special session is (a) for participants to present papers describing measurements on current common test cases (including NACA 63018, NACA 0012 and 30P30N airfoil configurations) or a configuration they would like to propose as a common test case, and (b) for participants to present papers describing quantitative and comparative characterizations, or methods for characterization, of Hybrid Anechoic Wind Tunnels using laser impulse calibration.

12 January 2022 (19:00 US Eastern, Midnight UK): Extended abstract due
23 February 2022: Notification to authors
17 May 2022 (19:00 US Eastern, Midnight UK): Final manuscript submitted on-line
14 to 17 June 2022: Conference dates
An extended abstract of at least 1000 words, with key figures and extended references to existing publications is required. Authors must clearly identify in the abstract new or significant aspects of their work. Abstract reviewers will base their recommendations on acceptance or rejection on:
• Whether the abstracts meets the requirements described above
• The relevance of the work
• The originality of the work
• Contribution to the field: does it advance the current state of knowledge?
• Are significant results presented to ensure timely completion of the paper?
Abstracts will be due no later than 12 January 2022. Authors will be notified of paper acceptance by 23 February 2022. An Authors Kit, containing detailed instructions and guidelines for submitting papers to AIAA, will be made available to authors of accepted papers. Authors of accepted papers must provide a complete manuscript to AIAA online by 17 May 2022 for inclusion in online proceedings and for the right to present at the conference. It is the responsibility of those authors whose presentations or papers are accepted to ensure that a representative attends to present the paper.
Sponsor and/or employer approval of each paper is the responsibility of the author. Authors should determine the extent of approval necessary early in the paper presentation process to preclude paper withdrawals or late submission.
“No Paper, No Podium” and “No Podium, No Paper” Policies
If a written paper is not submitted by the final manuscript deadline, authors will not be permitted to present the paper 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 in person. If a paper is not presented at the conference, it will be withdrawn from the conference proceedings. These policies are intended to eliminate no-shows and to improve the quality of the conference for attendees.
We are pleased to be able to offer a full in-person conference this year, and the response from speakers and delegates looking to join us in Southampton has been fantastic. Recent easing of Covid-19 restrictions in the UK and elsewhere has confirmed this decision. Please note that we will consider facilitating online access, but only for those impacted by nationally enforced travel restrictions. For specific requests please contact email@example.com.
