What acoustic treatment is best for a vocal booth?

Acoustic absorption is the desired acoustic treatment for a vocal booth. Our acoustic foam panels are a great option for acoustic absorption. Some other options are fabric covered acoustic absorbers, natural cork absorbers or DIY acoustic panels. 

The vocal speech of an average adult male has a frequency range from 85 to 180 Hz, and an adult female from 165 to 255 Hz.

One inch thick acoustic foam will do the job if you are on a budget, but two inch thick or thicker foam is best. Below are the absorption ratings of our acoustic foam.

How much acoustic treatment does a vocal booth need?

When recording vocals it is better to have dry sound with little to no reverb. You can always add reverb after recording. It is hard to take reverb out of a bad recording!

To achieve a dry sound a fair amount of coverage of over 50% is recommended. Some vocal booth have up to 100% coverage. The important thing is that the reverberation time is 0.5 seconds maximum

Flat surfaces reflect sound and cause echo and reverberation. For a vocal booth the flat surfaces will need covered with absorptive material like acoustic foam so echoes are reduced and reverberation time is lowered. 

Where to place acoustic treatment in a vocal booth?

Place acoustic absorption at the reflection points. The reflection points for recording vocals are the areas you are speaking or singing towards. For example, if you are recording towards your computer at a desk the reflection point is behind your desk.

Coverage all the way to the floor is not necessary. Placing acoustic treatment towards the floor will not provide much benefit. It is good to stick to the top 75% of the wall and the ceiling. 

Focus on the area where you will be recording. If you are recording in a bedroom and need to get vocal recordings with less echo you do not need to treat the entire room. Rather, you can focus on the area of the room where you will be recording like the corner, by your desk, or in a closet. Placing acoustic foam all around the room is not likely necessary.
