Jul 02, 2019 · The TL is identified with a number value between 0 and 1 and rounded to the nearest tenth (0.1). Zero (0) means no loss, and one (1 or 1.0) means 100% of the sound is blocked or absorbed. STC Class:What Can We Hear? The average human ear begins life hearing sounds between 20 Hz and 20,000 Hz.

NRC refers to a surface's ability to reduce noise by absorbing sound or the percentage of sound energy not reflected by the panel, which ranges from 0 to 1.0. Is a higher or lower STC rating better? Higher STC ratings generally are better. What is STC & OITC? Soundproof San DiegoThe Sound Transmission Class (STC ) is a single-number rating of how well a material or building partition attenuates airborne sound at frequencies:125 Hz, 250 Hz, 500 Hz, 1k Hz, 2k Hz, and 4k Hz. STC ratings are widely used to rate interior partitions, ceilings and floors. Other materials that can use STC as a rating system are doors, windows
- NameRatingsPhonologyDefinitionEquipmentImpactUnderstanding STC and Measuring Sound Loss - In 1961, STC was introduced as the method for comparing various wall, ceiling, floor, door, and window assemblies. STC is calculated by taking the Transmission Loss (TL) values tested at 16 standard frequencies over the range of 125 Hz to 4000 Hz and plotted on a graph.
Workplace Research Noise at Work - Knollsound. An NRC value of 0.2 and higher is considered sound absorbing, while an NRC value of .19 and lower is considered reflective. NRC is typically used to measure sound absorption for floors, ceilings and wall assemblies. Sound Transmission Class (STC):A numerical rating that indicates the transmission of sound through construction materials.
The sound transmission coefficient (STC) rating spans speech frequencies and is relevant for separation of spaces with conversational and other occupant-generated noise.
