Final answer:

Microphones convert sound pressures into electrical signals that are in the form of mechanical waves.


Explanation:

Microphones are pressure transducers that convert sound pressures into electrical signals. The recorded waves by a microphone are mechanical waves that are converted into electrical signals by inducing an emf in a coil. When sound waves hit the diaphragm of a microphone, it causes the coil to vibrate near a stationary magnet, producing current due to Faraday's law.
