Welcome to The ASA Computational Acoustics Technical Committee.

Philadelphia Meeting Gallery of Acoustics

13 April 2026: Deadline for notice of intent to submit.

27 April 2026: Deadline for the receipt of all entries and materials.

The Technical Committee on Computational Acoustics will sponsor the 20th Gallery of Acoustics at the 190th Meeting of the Acoustical Society of America (ASA).   Its purpose is to enhance ASA meetings by providing a setting for researchers to display their work to all meeting attendees in a forum emphasizing the diversity, interdisciplinary, and artistic nature of acoustics. The Gallery of Acoustics provides a means by which we can all share and appreciate the natural beauty, aesthetic, and artistic appeal of acoustic phenomena: This is a forum where science meets art.  Additionally, many computational aspects of acoustics are more easily explained in video form where additional dimensions can be displayed.  Participation is open to all meeting attendees.

The Gallery will consist of a collection of short videos detailing results generated via computational acoustics or describing the computational approach. Videos can consist of actual visualizations of acoustic processes or of aesthetically and technically interesting images resulting from computational techniques and data visualization. The top 3-8 submitted entries are then displayed in a main lobby of the conference hotel for all to see. Video entries must be limited to 3 minutes in duration (STRICTLY ENFORCED), and must be submitted electronically, by e-mail attachment or link to web location where they can be downloaded.   Videos should be in MP4 format with H.264 video and AAC audio encoding to facilitate ease of compiling videos and playback.  If any AI-generated video is included, it must be clearly labeled.

Entries must be accompanied by all authors’ names and affiliations, a title, a brief description of the entry and importance or interest of the entry (no more than 200 words), and statement of permission to display the entry at the meeting. Please indicate the primary point of contact. The meeting attendees will vote on the entries on the basis of aesthetic/artistic appeal, ability to convey and exchange information, and originality. A cash prize of USD $250 and $150 will be awarded to the winning and first runner-up entries, respectively.

(1) 13 April 2026: Deadline for notice of intent to submit. Include a title, full contact information for the lead author, and a basic description of the proposed entry. This information will not be published anywhere, rather it is used to help guide entrants in their submissions. Please indicate the primary point of contact.

(2) 27 April 2026: Deadline for the receipt of all entries and materials. For digital entries please provide a link to your work. In addition, please provide a complete author list with affiliations and an abstract describing the entry.

Entries, questions, and all other communications regarding the Gallery should be directed to: Ralph Muehleisen, T: 630-252-2547 E-mail:  rmuehleisen@anl.gov

The technical scope of the Computational Acoustics Technical Committee includes the following topics:

  • Numerical methods for acoustic wave propagation, scattering, structural interactions, and other acoustically related phenomena.
  • Optimization, parallelization, and acceleration of computational algorithms.
  • Validation, benchmarking, and uncertainty analysis in computational models.
  • Computational learning methods, data analytics, and visualization.
  • Practical utilization of acoustical computations for engineering and noise control, and integration into other simulations.
This is a numerical simulation of noise generation from an over-expanded supersonic jet. The computation uses the time marching Dispersion-Relation-Preserving (DRP) scheme. Unlike CFD schemes, DRP scheme, a CAA scheme, is designed to compute accurately fluid flow and sound propagation simultaneously. It is proven mathematically that DRP scheme would reproduce the sound wave speed, wavelengths and other wave characteristics as those of the governing PDE. Since a finite computational domain is used, radiation and outflow boundary conditions are imposed at the exterior boundaries. For over-expanded supersonic jets, the nozzle exit pressure is not the same as the ambient pressure. To ensure this is reproduced in the simulation, a set of improved radiation boundary conditions is adopted. This movie shows Mach wave radiation in the downstream direction and screech tone radiation in the upstream direction (see the circular bands of sound waves in the lower left side of the movie). The Mach wave and screech tone radiation in the simulation are found to be in good agreement with experiment.
