Acoustics Ray Refraction in the Atmosphere
Application ID: 128681
This example model simulates the long-path echo of trumpet sounds reflected from a building 500 m away. The echo can only be heard at night because of the acoustic ray refraction in the atmosphere with different temperature profiles.
The model is solved using the ray tracing in the graded medium capabilities of the Ray Acoustics interface.
The example has three steps.
Step 1: Simulating the temperature profile in the atmosphere during the day and at night, using Heat Transfer.
Step 2: Simulating the radiation pattern of the trumpet bell using Pressure Acoustics, Frequency Domain
Step 3: Simulating the long-path echo using Ray Acoustics.

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.
