Definition of Transmission loss
Transmission loss (TL) in general describes the accumulated decrease in intensity of a waveform energy as a wave propagates outwards from a source, or as it propagates through a certain area or through a certain type of structure.
It is a terminology frequently used in radio communication, twisted pair systems (PTSN, Ethernet, etc.), optics and acoustics. Measures of TL are very important in the industry of acoustic devices such as mufflers and sonars.
