Transmission Loss
</dt>
The reduction in the magnitude of
some characteristics of a signal between
two stated points in a transmission
system. Also called loss. The characteristic is often some kind of
level, such as power level or voltage level; in acoustics, the characteristic
that is commonly measured is sound pressure level. Thus, if the levels are
expressed in decibels, the transmission level loss is likewise in decibels. It
is imperative that the characteristic concerned (such as the sound pressure
level) by clearly identified because in all transmission systems more than one
characteristic is propagated. [[/a>|/a>
