audio frequency

An audio frequency generator produces a steady tone for a hearing test.

Definition
  1. Noun:
    • A frequency of acoustic waves that can be heard by the human ear: "audio frequency" refers to a periodic vibration whose rate falls within the typical range of human hearing, generally considered to be from about 20 hertz (Hz) to 20,000 Hz.
Usage
  • The term "audio frequency" is used in technical contexts related to sound engineering, acoustics, electronics, and telecommunications to describe signals or waves within the audible spectrum.
  • It specifies the range of vibrations that, when transmitted through a medium like air, are perceived as sound.
Examples
  • Noun:
    • The microphone is designed to capture sounds across the entire audio frequency spectrum.
    • A dog whistle produces a sound at a frequency above the typical human audio frequency range.
Advanced Usage
  • "Within audio frequency": describes a signal or wave whose frequency is in the audible range.
    • The tone generator creates signals within audio frequency for hearing tests.
  • "Audio frequency signal": a common technical compound referring to an electrical signal that corresponds to a sound wave.
    • The amplifier processes the audio frequency signal before sending it to the speaker.
Variants and Related Words
  • Audible frequency: A synonym for audio frequency.
  • Sonic frequency: Another synonym, often used in physics and engineering.
  • AF (abbreviation): A common abbreviation for "audio frequency" in technical schematics and documentation (e.g., AF amplifier).
  • Infrasonic: Refers to frequencies the audio frequency range (below 20 Hz).
  • Ultrasonic: Refers to frequencies the audio frequency range (above 20,000 Hz).
