An electrical signal is converted into an acoustic wave (vibration) using a transducer, often piezoelectric.
The vibration travels through a medium—such as a liquid (mercury), solid (silicon, quartz), or gas (air)—at the speed of sound for that material. acoustic delay line
An (ADL) is a specialized physical device that uses sound waves to introduce a precise time lag into a signal . By converting electrical signals into slower-traveling mechanical vibrations, these devices can "store" or delay information in a much smaller physical space than would be required by electrical transmission lines.
