Foundation
Healthy and good-sounding acoustic environments for everyone
OUR VISION
Modern acoustics solutions for healthy, good-sounding environments increasingly depend on software. Yet many valuable research codes remain difficult to discover, reuse, and sustain. The Open Acoustics Foundation exists to democratize acoustics research and promote open, reproducible science by supporting the community initiatives that make this possible.
Sustainable foundation
The foundation revolves around (and is carried by) multiple stakeholders: researchers to provide new results and methods, sponsors and donators to enable maintaining and further developing the tools and to organize community events, and users to use the tools created and provide valuable feedback for improving them.
Community driven
The foundation supports community initiatives around open research results and methods, which are aimed at collaboration and growth of the community.
Open Source
The open source principle is key: all results and tools are openly made available to the public, for free and without limitations.
Impact vehicle
Innovative research developments are carried out outside the foundation, at universities and research institutes, while the foundation acts as an impact vehicle for the research results.
News & Events
To secure a sustainable software platform connected to its community
Autumn '26 - CHORAS event
A new CHORAS community event will take place, more info will follow later!
The Open Acoustics Foundation will be publicly launched at Forum Acusticum in Graz.
May '26 - Open Acoustics Foundation founded
The Open Acoustics Foundation was founded on May 13th in Eindhoven.
TU/e Bachelor students of the Room Acoustics Course and Master students of the Techniques in Architectural Acoustics course use CHORAS to analyse and improve spaces.
Developers of open-source room acoustics simulation tools work together in Eindhoven to connect their methods to CHORAS.
Users explore CHORAS while using it and provide feedback and ideas to improve the platform.

OUR PROJECT
The first project supported by the foundation is CHORAS, the Community Hub for Open-source Room Acoustics Software. CHORAS is a web-based platform that brings together the newest room acoustics simulation methods: making them accessible to researchers, consultants, and students worldwide via an intuitive browser interface.
Built on open-source principles, CHORAS and its connected third-party back-end software projects are freely available.

Questions
The vision of the foundation is to create healthy, comfortable and well-sounding buildings and living environments for everyone
The foundation believes this is achievable by its vision to increase the impact of research institutes: democratising research results in the field of acoustics in the built environment, and promoting science that is open, transparent and reproducible.
Much valuable acoustic software or tools disappear once a research project ends, or remains accessible to only a handful of insiders.
We contribute to our mission and vision by supporting open-source projects and their communities in the field of acoustics: giving them visibility, organising events, and providing funding for software maintenance.
The foundation is a non-profit and independent organization. Its purpose is not to generate profit, but to maximize the impact, accessibility, and long-term sustainability of open research outcomes. This creates a neutral platform where collaboration and knowledge sharing come first.
Our work benefits a broad community. Researchers gain a platform to share and build upon scientific developments, industry gains access to reliable tools and methods, educators can use open resources in teaching, and society benefits from improved knowledge and innovation in acoustics.
Support can take many forms. Researchers can contribute methods and software, users can provide feedback and participate in the community, and organisations can sponsor to facilitate activities, events, and platform development. Together, these contributions help ensure the long-term availability of open and reproducible acoustics research and its communitiy.
