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% 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 this ...
