We are happy to answer your questions regarding our products and how we can best solve your sound & vibration needs. If you would like to brush up on the basics, please take a look below.

Sound Basics

Decibel (dB) – A unit used to measure the intensity of a sound or the power level of an electrical signal by comparing it with a given level on a logarithmic scale. Or in simpler terms, the scale used to measure how loud something is.

Frequency (Hz) – The rate at which a vibration occurs that constitutes a wave, in a material (as in sound waves) usually measured per second. Often referred to as pitch or tone.

Sound Loss Basics

Transmission Loss – The measure of the decibel loss from one side of a barrier to another. This can be found in any situation where there is a physical barrier. The concept of transmission loss is crucial to understand which product best suits your needs.

STC Rating – The STC rating is how the noise isolation performance of the products we offer are quantified, with a higher STC rating generally offering a higher transmission loss. The STC rating is calculated by taking transmission loss values at various frequencies and is compared to standard STC reference values.
