Examples of Use

1. Music: In music, tones are the building blocks of melodies and harmonies.
2. Acoustics Testing: Pure tones are used to test the frequency response of audio equipment and hearing capabilities.
3. Communication Signals: Tones are used in telecommunication systems for signaling and data transmission.

Related Terms
