    Set the frequency range to 15Hz, and the variable control to 100Hz (or 120Hz if you are in the US or anywhere else 60Hz is used). Using a set of headphones, you should be able to hear the 50 (or 60) Hz hum softly. Now increase the oscillator level control, and a second tone should be audible.

What is an audio frequency oscillator? - Quora

    https://www.quora.com/What-is-an-audio-frequency-oscillator
    An "audio frequency oscillator" is an electronic device that can generate an alternating voltage waveform. They are typically inexpensive and fairly simple. Usually they are able to generate several waveform types, including sine, square, and triangle waves, as well as pulses of variable length, with easily-adjustable output frequency.
