  • Turn Off Noise Makers

Identify anything that is making noise in your room; turn it off. Turn off air conditioners, fans, refrigerators, washers, computers and any other background noise. If you have a loud air vent turn it off when you start recording.

  • Soundproof Your Room

You might not be able to turn off every noise in your room. Other times you won’t have any control of the sound coming from outside. Therefore, soundproof your recording room. Seal all the gaps on the walls, windows, doors, and ceiling.
