آکوستیک اتاق زمان دامنه تمام موج با امپدانس وابسته به فرکانس – کامسول

Simulating the room acoustic response using a full-wave method has been made possible in the last years due to the increase in computational performance as well as the development of new numerical methods. The challenge of including realistic impedance conditions at walls is traditionally solved in the frequency domain. Resent research is focusing on time-domain models using time explicit methods that are very memory efficient.

This tutorial shows how to set up a user-defined system of ODEs in order to model a frequency-dependent impedance condition in a full-wave time-domain room acoustics simulation. The model studies the response of a small 50.5 m3 room.

The model uses the Pressure Acoustics, Time Explicit physics interface together with the Boundary ODEs and DAEs mathematics interface. The two can be solved simultaneously.
