Streamer Room Acoustics & RT60 Decay Calculator
Stop your high-end broadcast microphone (Shure SM7B, Rode PodMic, Audio-Technica) from sounding like you are recording in a bathroom. Calculate your room's reverberation decay time (\(RT_60\)) and determine how many absorption panels you need for studio-grade broadcast dryness.

Acoustic Engineering VerdictNear Broadcast Spec
With 8 high-density panels, reflections are significantly tamed. Adding 6 more panels near first reflection points (beside monitor and directly behind head) will achieve the pristine 0.25s podcast benchmark.
