Measuring sound transmission The amount of noise that a building element (such as a wall, floor, door or sheet of glass) is capable of stopping is expressed as a sound transmission class (STC) rating. The higher the STC number, the greater the noise reduction. For example, a wall with an STC rating of: 30 dB has little sound-control effectiveness

STC rating (Sound Transmission Class rating) is a score given to a building’s surface (wall, ceiling, window, etc.) based on its ability to reduce sound coming through it. STC rating goes from 25 – 65. The higher the rating, the less noise penetration. A rating of 25 is no soundproofing, and 65 is complete soundproofing. The STC rating (Sound Transmission Class) is used to rate the transmission loss of construction, or how much of a sound transmits through a material (typically a partition). The higher the rating, the better the performance of stopping sound. With an STC rating of 25, normal speech can be heard clearly through a barrier.
