An application running on a mobile device, Soundar, was developed for simple acoustic simulations for small size rooms and for ordinary users. It simulates the reverberation time and sound pressure level based on an existing room, virtual sound source, and the location of the user. Users can change the material of the room surfaces and then test the difference in sound. The application provides both visual and auditory feedback that will let the users not only read the data but also hear the result of the simulation.
