Study Notes
Sound Transmission Measurement
- Sound transmission class (STC) measurement calculates the effectiveness of soundproofing materials.
- STC measures the approximate decibel reduction of a material.
- Materials with higher STC values are better for reducing sound transmission.
- Materials with higher NRC values are better for absorption of sounds.
Acoustic Design and Detailing
- Acoustic control is important in reducing noise in various spaces like gymnasiums, theaters, offices, etc.
- Materials are selected to control noise and keep sounds low.
- Soundproofing materials absorb and reflect sounds to minimize noise.
- A higher STC value means a better job of keeping noise out of a room.
