Thank you for this explanation, in the case of the brick wall, how can we determine the sound absorption?

You're welcome. We cannot determine sound absorption of brick in this example because it's a free field space. I will record a video about it in the future.

@@caewitharminhashemi Hello sir until then can you give some hint how to specify the analytical model to (DB/JCA) here to give sound absorption of the barrier material?

Hi sir, while going through one research paper on barrier simulation, source was defined outside the domain and scattered field formation was given to define distribution of noise inside the domain..will you pls tell how to give that kind of condition?

Hello. I did understand. What do you mean source is outside the domain?

Also sir can we specify Fresnel no and find out insertion loss as well?

I haven't seen frensel number in results. Maybe you should define it. Yes you can calculate insertion loss.

Hello sir how can we model sandwitch barrier model consisting of two layers of aluminium sheets with some porous material in between?

Hello. Create three layers. Two layers for aluminum sheets and one layer for poroacoustics material.
