In order to hear what a microphone is doing, we need some sort of play device such as a loudspeaker or a pair of headphones. But do microphones need these playback devices in order to function? If a tree falls in the wood with no one to hear it, does it make a sound?
Do Microphones Need Loudspeakers Or Headphones To Work? Absolutely not, though it’s very useful to have speakers and/or headphones to monitor the mic during recording and to listen to the recordings of the mic. Microphones convert sound into electrical signals and do so whether their signals are converted back to sound (via speakers/headphones) or not.
