The Science of Sound Control
Laminated glass attenuates sound thanks to its sturdy interlayer. This greatly reduces audio decibel levels and is extremely useful in high-noise areas, such as near major roads, airports, and manufacturing centers. And when paired with a sealed IG unit, Cardinal’s laminated glass renders even greater sound dampening. STC and OITC are standards that measure sound attenuation. Widely used STC (Sound Transmission Class) measures frequencies from 125 Hz to 4000 Hz. OITC (Outdoor-Indoor Transmission Class) is a more modern and “real world” test that includes sounds on the lower end of the spectrum, from 80 to 4000 Hz. In both cases, the higher the number, the better the sound deadening effects.

Note how glass thickness and interlayer configurations affect sound control. Higher STC/OITC numbers are better.
