In this poster the acoustic analysis of a small home recording studio is presented.. Figure 1 illustrates the recording studio room which was simulated using the COMSOL Multiphysics® software with the Acoustics Module [1]. The propagation of sound is modeled as pressure waves in which modal analysis is performed in the frequency domain [2]. Lower eigen-frequencies are the most critical to understand when dealing with room acoustics. Figure 2 illustrates typical results of the model correlation/mesh independence study of our investigation. Figure 3 shows the results of acoustic analysis assuming sound hard wall boundary conditions. The speakers were driven in the room via a point load boundary condition. Typical results for this “speaker projection analysis” are given in Figure 4. Information
