Sähköakustinen
Sähköakustinen refers to the interaction between electrical and acoustic phenomena. This broad term encompasses devices and processes where mechanical vibrations are converted into electrical signals, or where electrical signals are used to produce mechanical vibrations.
A primary example of sähköakustinen technology is a microphone. Microphones convert sound waves, which are acoustic
Conversely, loudspeakers and headphones operate on the principle of converting electrical signals back into acoustic vibrations.
The field of sähköakustinen is also relevant in musical instruments, particularly those that are electronically amplified
