Do It Yourself Room Analysis-Acoustics Forum-Acoustic Fields Forum

Room size is:
Length: 17.06′
Width: 11.28′
Height: 8.46′

I have the Window on the back wall (in my back) = Length 6.39′ x height 4.46′
Door (on the left wall, unfortunatly on the left of me kinda at the first reflection) = Length 6.56′ x height 2.62′

Floor: lamiated parquet
Walls: poured concrete and is 0.5′
+ back wall (the one with the window) is 1.8′

Room usage: Video editing (audio also for advertising, documentaries etc), Recording 1-2 persons podcast and mixing that audio.
Speakers: 2 channels Tannoy Gold 8.
Microphone for voice recording: Shure SM7B

I would like also to soundproof a little bit for not getting sound out. Getting sound from “outside” the room, at the hours that I am working in, is not really an issue.
