What is the term for equipment that provides audio for a live audience?

The term "sound reinforcement" specifically refers to the use of audio equipment, such as microphones, speakers, and amplifiers, to enhance the sound for a live audience. This process involves capturing the live performance or presentation and amplifying it so that it can be heard clearly by an audience, regardless of the venue size or distance from the performers. Sound reinforcement is crucial in theatre, concerts, and public speaking events to ensure that the sound is not only loud enough but also clear and balanced.

Sound effects refer to pre-recorded sounds that add auditory elements to a performance, rather than amplifying live sound. Acoustic amplification, while related, focuses more specifically on improving sound production through natural means rather than using mechanical or electronic systems. Audio mixing involves adjusting the balance and levels of different audio sources, but it does not encompass the overall system aimed at delivering audio to an audience; it's more about the creative process behind the sound rather than the act of delivering it live. Thus, "sound reinforcement" accurately captures the essence of providing audio for a live audience.
