Define room acoustics material properties via the TB,AFDM,,,,ROOM command. Use the TBDATA command to input (in this order): the empty room diffusion coefficient, the coefficient of atmospheric attenuation, the furniture diffusion coefficient, and the furniture absorption coefficient.
Example 5.10: Defining Material Properties for Room Acoustics
The following example input defines material properties for room acoustics:
tb,afdm,1,,,room ! diffusion properties for room tbdata,1,roomD,attn,fitD,fitattn
