Glossary
Absorption coefficient This indicates how much sound energy will be lost during the transition at a surface. Absorption coefficients range from a maximum of 1.00 (an open window) to 0.00 (100 per cent reflection).
Active balanced interconnection A balanced line connection to or from a powered (active) input or output device.
Active electronic device An audio device that receives power from an external source (or battery) in order to carry out its signal processing functions. An active device is capable of providing amplification of the signal.
Air absorption loss High-frequency attenuation that accrues over transmission distance in air. The humidity, ambient temperature and atmospheric pressure all play a part in the parameters of ...
