Audio Tone & Frequency Generator (20Hz – 20kHz)

Audio & Sensors

Precision oscillator generating sine, square, sawtooth, and triangle waves across human hearing range to test buzzing and coil whine.

Frequency (Hz):
Quick Actions Ready
Acoustic Diagnostics: Frequencies around 100-300 Hz reveal loose speaker chassis screws or damaged diaphragms (rattling sound). Sweeping above 12 kHz tests tweeter fidelity in headphones.

Frequently Asked Questions

What frequency range can the human ear detect?

The typical healthy human hearing range spans from 20 Hz (deep sub-bass) to 20,000 Hz (20 kHz, high treble). Higher frequencies naturally decline with age.

What are the differences between Sine, Square, and Sawtooth waveforms?

A Sine wave contains only the fundamental frequency with zero harmonics. A Square wave contains odd harmonics producing a harsh digital buzz. A Sawtooth wave contains both even and odd harmonics, widely used in audio synthesis.

How do repair technicians use audio tone sweeps?

Sweeping from 20Hz to 20kHz allows technicians to identify physical chassis buzzes, loose speaker adhesives, damaged diaphragms, or crossover frequency roll-offs.
