We manufacture an extensive range of industrial acoustic curtain panels tailored to your noise objectives and budgetary constraints.
In this case, if there is a 100 decibel sound and it is reduced by 10 decibels, the new sound level would be around 90 decibels. The reduction of 10 decibels would make the sound appear to be about half as loud to the human ear compared to the original 100 decibel sound.
It’s important to note that perceived loudness can vary depending on various factors, including individual sensitivity and the nature of the sound itself. Additionally, the perception of loudness is not a linear relationship with decibel levels, but rather follows a logarithmic scale. As a result, small changes in decibels can have significant effects on our perception of loudness.
To effectively manage noise, it is crucial to address all surfaces within the room. Noise tends to reflect off various hard surfaces, including ceilings, walls, shelves, machinery, and floors. By incorporating wall, ceiling, and corner baffles, the noise can be dampened, allowing soft materials to absorb and trap the sound before hitting the hard surfaces.
In addition, covering the flooring with rubber mats or carpets can further contribute to noise reduction.
If you are planning to enclose the source of the noise, it is essential to seal all edges tightly. This prevents sound leakage and ensures maximum effectiveness. Additionally, incorporating baffles within the enclosure is highly recommended. Baffles help dampen and reduce the overall noise within the enclosure, providing further control over sound levels.
While our acoustic curtains/panels are primarily designed for indoor use, we have received positive feedback from customers who have utilized them for outdoor or semi-outdoor applications. It is important to note that the warranty provided for our acoustic curtains is limited to indoor usage. However, we are pleased to inform you that our curtains have demonstrated satisfactory performance.
Hanging the industrial sound dampening curtain panels to fit as an acoustic accordion door increases the overall audible absorption by defusing acoustic energy from parallel surfaces in the room.
Add industrial double barrier acoustic panels or industrial acoustic 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
the sound.
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.
