Using Insertion Gains to Evaluate Railway Vibration

However, it is the inverse of Insertion Loss – termed Insertion Gain – that is becoming the norm in quantifying and specifying the vibro-acoustic performance of a track system for several reasons.

Insertion Loss

An insertion loss represents the decrease in noise level due to the presence of the barrier compared with a case where no barrier exists. Higher insertion losses are possible when barriers are placed
