The Bible states the concept of audio signals traveling out of speakers can vibrate the wall they touch or are close to it the sound waves fed through the speaker travel in every direction.
In Habakuk 2:11 “The very stones in the walls cry out against you, and the beams in the ceilings echo the complaint.
A sound reinforcement system is the combination of microphones, signal processors, amplifiers, and loudspeakers in enclosures all controlled by a mixing console that makes live or pre-recorded sounds louder and may also distribute those sounds to a larger or more distant audience. In many situations, a sound reinforcement system is also used to enhance or alter the sound of the sources on the stage, typically by using electronic effects, such as reverb, as opposed to simply amplifying the sources unaltered.
