How Much Sound Deadening Do I Need?

You’ve taken your Neurobiologix for your hearing. You’re getting ready to record something brilliant.

Everything is set up, but the sounds aren’t recording in your DAW as expected. What is happening?

If you don’t have enough sound deadening in a recording space, the echo can impact any microphone set to capture sound. When there’s too much, the audio can sound hollow or tinny.

Do You Need Acoustic Treatments?

Acoustic treatments provide sound deadening options by diffusing noises that bounce on walls and ceilings. You can hang rigid fiberglass panels around a room to create this effect, especially if there isn’t any insulation batting behind the drywall.

This option turns the audio into heat, which means the microphone only picks up the first sound pass. You need a minimum of 25% coverage to make a positive impact.

What About Bass Vibrations?

Although you can have plenty of acoustic treatments, the materials won’t deaden the vibrations coming from the lower frequencies. Those travel through a wooden frame, along the drywall, and into the microphone stands.

You’ll need to invest in a high-quality shock mount for your at-home recording needs. Some caulking in the walls can also stop the vibrations from traveling through the room’s infrastructure. 

Do You Need Isolation Pads?

Isolation pads are foam cushions used for subwoofers and monitors. The speakers sit on them to prevent audio vibrations from getting picked up by other devices.

That allows you to decouple your structures to ensure you’re laying tracks with pure sounds instead of with lots of background noise or interference. 

You’ll also need to cover any metal bracing or components in the room’s structure with foam padding to eliminate additional vibrations. By taking these steps, you’ll take care of the sound deadening needs for your recording.
