Amplification of live sound sources. Speed of Sound - The speed of sound waves, about 1130 feet per second in air.
The process of amplifying or reinforcing on-stage sound (whether from already-amplified or acoustic instruments/voices) without overpowering the original sound. Suitable for smaller venues and often used solely to raise the level of the vocals above the back line and drums.
A system of amplifying acoustic and electronic sounds from a performance or speech so that a large audience can hear clearly. Or, in popular music, so that a large audience can be excited, stunned or even partially deafened by the tremendous amplification. Means essentially the same thing as PA (Public Address).
The use of amplification to project and reinforce sound for an audience. Speakers: Devices that convert electrical signals into variations in sound pressure.
The act or application of audio processing equipment to reinforce and amplify sound instantaneously. Adding the processed sound to that of natural sound from the sound source so that all can hear. One of the three major applications of audio equipment as opposed to recording or broadcast. Sound reinforcement takes a weak sound and makes it loud enough for people to hear.
Reinforcing the sound produced by the actors on a stage. This is very different from amplifying the sound (as happens when a vocalist uses a mic to be heard above a band), for the audience should not be aware of the amplification. It is much more complex to achieve and requires greater sensitivity on the part of the operator.
The use of electronic devices to reinforce, alter or increase the level of sound.
Amplifying a voice just enough so that it can be heard, without the audience being aware that it is being amplified (ideally!)
Electronically amplifying an acoustic sound source such as a talker. Sound reinforcement systems typically use microphones, amplifiers and loudspeakers.
