TruVoicelift TeamConnect Ceiling 2 Glossary AEC EAD AV dB DSP EQ FSM GBF NAG PAG PA SR RT RT60 Acoustic Echo Cancellation AEC is used to remove echoes, reverberation and unwanted additional noise from a signal passing through an acoustic space. This function is mostly needed when a person is connected via a remote connection, known as "far end." Equivalent Acoustic Distance Distance between the talker and an un-aided listener. Audio-Visual Involving the use of recorded pictures and sound, or the equipment that produces them. Decibels A unit for measuring the loudness of sound. Digital Signal Processing Used for digital encoding of "live" signals such as audio, video etc. and allows these signals to be stored, manipulated, edited, replayed, and transferred much more efficiently and accurately than with strictly analog methods. Equalizer Electronic equipment that adjusts (= makes slight changes to) the frequency of recorded sound to make it sound better. Feedback Stability Margin Stability value which is determined and used for robustness against disturbances. Gain-Before-Feedback A practical measure of how much a microphone can be amplified in a sound reinforcement system / voice lift system before causing audio feedback. Needed Acoustic Gain Value, in decibels, that the system requires to perform effectively. Potential Acoustic Gain Potential maximum amplification, in decibels, that the system can produce before feedback occurs. Public Address System Equipment for making sound louder in a public place. Sound Reinforcement System System of microphones, signal processors, amplifiers and loudspeakers that ensures controlled mixing and distribution of live sound to a larger or more distant audience. Reverberation Time The time required for reflecting sound to fade away in an enclosed space after the source of the sound has stopped. Reverberation Time 60 The period of time required for the sound pressure level to decrease by 60dB after a sound source is abruptly turned off. RT60 is also a common abbreviation for Reverberation Time. AN 1300 v1.1 | 01/22
