Sound Absorption Coefficient:

A measure of how much sound is absorbed by a material compared to the amount that strikes it, typically ranging from 0 (no absorption) to 1 (total absorption).

Reverberation Time:

The time it takes for sound to decay by 60 decibels in a given space, which affects how sound is perceived in terms of clarity and fullness.

Transmission Loss:

The reduction in sound energy as it passes through a material or barrier, important for understanding how well a building's structure can block noise.
