Small Concert Hall Acoustics
Application ID: 20145
Designing structures and open spaces with respect to sound quality is important for concert halls, outdoor environments, and even the rooms of a house. Simulating acoustics in the high-frequency limit, where the wavelength is smaller than the geometrical features, can be done with ray acoustics.
There are several advantages to modeling ray acoustics, including changing media properties and assigning various wall conditions, among others. The wall conditions can be complex valued and depend on both frequency and angle of incidence.
This model analyzes the acoustics of a small concert hall using the Ray Acoustics physics interface. The model setup includes an omnidirectional sound source, wall boundary conditions for specular and diffuse scattering, sound pressure evaluation on a boundary, a Receiver data set, an Impulse Response plot, and an energy decay curve. The results are compared to a simple reverberation time estimate.
This model example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Grille des Spécifications and make use of a free evaluation license.
