Description:STC = STC Rating (from 0 to 100)Frequencies = a sequence of frequencies from 125 to 4000 Hz

Introduction to Sound Transmission Class (STC) Rating

The Sound Transmission Class (STC) rating is a single-number rating of a material's or an assembly's ability to resist the passage of airborne sound. In this formula, STCrepresents the Sound Transmission Class rating, and frequenciesare the sequences of frequencies that are tested to obtain the STC Rating.

Data validation

The STC Rating should be between 0 and 100. Frequencies should be between 125 and 4000 Hz.

Summary

This formula is used to assess the ability of materials or assemblies to reduce the transmission of airborne sound. It is widely used in architecture, construction, and interior design to measure the sound insulation performance of walls, windows, doors, and other building components.
