acoustic signals

Acoustic signals are sound waves that transmit information, created when a source produces vibrations that travel through a medium like air, water, or solids. These signals can be natural, such as animal calls or thunder, or man-made, like radio waves carrying music or speech. They are characterized by properties like frequency (pitch), amplitude (loudness), and duration. Acoustic signals are used in various applications, including communication, sonar detection, and medical imaging, allowing us to interpret and respond to our environment through sound.
