People most concerned with acoustic curtains are often either musicians or singers. They appreciate both the insulation from the outside noises and the flatter response of the room.
We will consider two main reasons why you, as a musician, would benefit from the acoustical curtains. We'll also provide pointers to choosing soundproof curtains both for sound attenuation and flattening.
We'll go over soundproofing with acoustical curtains and sound flattening with the soundproof curtains. For info on other types of acoustic/soundproofing curtains, see 3 types of soundproofing curtains on this blog.
Acoustical Curtains As Soundproofing Tool
A singer practicing singing in an apartment or even in a house, will likely be heard throughout the neighborhood unless he or she does something about the sound proofing.
The acoustical curtains will absorb a good portion of the sound produced by your voice or a musical instrument. This will reduce the disturbance of the neighbors. Conversely, you will hear a lower level of street and neighbor noise when practicing, which is an added bonus.
Flattening The Room Response, Removing Unwanted Echoes
You may get used to the room echoes when you are singing into the microphone or playing an instrument, and you may not consider the echoes disturbing.
You may only notice a huge difference when you enter a recording studio, or when you perform outside, in a place with no walls. Notice the difference? You will be less distracted by the echoes but you will also receive less feedback to your instrument playing or singing.
You may be shocked coming from a bare-walls room into a recording studio, and you may not perform that well. But when you have acoustical curtains in your practice room, you will be much better prepared for the studio conditions.
The acoustical curtains may look just like regular curtains, but are heavier, thicker. You can place them anywhere you want, on all four walls if that suits you. You can even keep them movable on caster wheels.
