Choose below from our Acoustic Curtain options:
Hanging the curtain panels in an “accordion pattern” increases the overall audible absorption by defusing acoustic energy from parallel surfaces in the room.
Add Dual Sided Absorption panels or Baffles to offer soft surfaces for the sound to absorb before reaching the hard surfaces in the room.
Dual Sided Absorption panels mostly used to be hung in front of hard surfaces for the sound to absorb in before getting reflected.
Free Hanging Baffles hung from the ceiling structure above the noise source to absorb the loudest noises as soon as possible.
Corner Baffles ready to absorb the collected acoustic energy in the corners.
NRC (Noise Reduction Coefficient) – used to measure noise reduction (through absorption) in the same space as the noise source.
STC (Sound Transmission Coefficient)- measures the Decibels loss of the sound going through an object.
NRC (Noise Reduction Coefficient) – used to measure noise reduction (through absorption) in the same space as the noise source. It is basically
a measurement of how well something absorbs sound, mostly in the range of normal speech frequencies. It is measured from 0 – 1.0 and can
be thought of as a percentage. The higher the NRC, the better it is at absorbing sound.
Example: A painted drywall wall has NRC of about .05, so it absorbs only about 5% of the sound that hits it and reflects back 95% of
STC (Sound Transmission Class) – A rating of how well a material/product attenuates sound. In simpler terms, it is how well an item blocks sound from going
through it. The higher the STC rating, the better sound isolation the wall will achieve. The STC rating is derived by measuring the transmission loss in dB at
certain frequencies and comparing it to a known STC curve.
Example: A metal stud wall with ½ in. thick drywall has an STC of 34. Cinder Block walls have an average STC of upper 40’s to low 50’s.
An STC rating in the upper 40’s is good. STC ratings in the 50’s are excellent.
Decibel (dB) is a logarithmic scaled unit of measurement. It is quite often used to define an intensity of a sound level or the power of an electrical signal. The dB scale is a easy way to define numbers that are normally very small to very large. When describing sound level in dB, the term dB SPL is used. (Sound Pressure Level) Humans perceived SPL changes as a perceived loudness. This is a scale where 0 dB SPL is the lowest level sound audible to humans and 125 dB is the threshold of pain.
The dB scale is logarithmic, meaning that a 10 dB decrease means that the sound level is perceived as half as loud.
