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 Sound Transmission Class (STC) is a single-number rating of a material's or an assembly's ability to resist airborne sound transfer at the frequencies 125-4000 Hz. In general, a higher STC rating blocks more noise from transmitting through a partition. STC is highly dependant on the construction of the partition.

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.
