What is "Sound Transmission Loss"? - inSync
https://www.sweetwater.com/insync/sound-transmission-loss/
Sound Transmission Loss (STL) represents the amount of sound, in decibels (), that is isolated by a material or partition in a particular octave or 1/3 octave frequency band.Example: 1/2″ drywall has an STL at 125 Hz of 15 dB.. Comparing material or partition performances for applications like recording studio isolation and sound proofing should …

Transmission loss of sound is a measurement of the reduction in sound level of a sound source as it passes through an acoustic barrier. It is the number of decibels that are stopped by the acoustical barrier or the wall and is measured at different frequencies. Heavier walls and acoustic barriers have a higher transmission loss than lighter materials. For example, a wall constructed …

1. Because of the large sound transmission loss in seawater, including geometric spreading and sound absorption, the sound intensity is rapidly attenuated with increasing propagating distances r.The input SNR (signal-noise ratio) for a specific receiver will correspondingly be lowered, or transmitting information cannot normally be detected.

The Transmission Loss module is available as an in-app purchase option in RTA. Also known under the names STC, NIC, OITC, and Rw, depending on the standard that is being used, the purpose of Transmission Loss measurements in any case is to determine how much acoustic attenuation a wall or divider will provide.

Transmission loss quantifies the effectiveness of acoustic treatments for an engineering application. Sound transmission loss can be defined as a ratio of the sound energy transmitted through a treatment versus the amount of sound energy on the incident side of the material. Equation 1: where W_i is the incident sound power, W_t is the ...

Sound Transmission Loss It gives the reduction in sound energy in dB, when sound wave passes through the component. In Building Acoustics, it is given as Sound Transmission Class (STC) which is an integer rating of how well a building partition attenuates airborne sound.
