What Is an Audio Frequency Generator?
Producing an electronic signal in the human hearing range of 20 Hz to 20,000 Hz, an audio frequency generator is used for the testing and adjustment of electronic equipment, graphing out human hearing and sound demonstrations.GeneratorsFunction generators, tone generators and audio frequency generators are all similar instruments. They have different features, but they all produce electronic signals within the human hearing range.TestingThe function generator produces a signal that is needed to test the frequency response of audio equipment. The signal level coming out of the audio equipment is measured at various frequencies and compared to the signal level going in.AdjustmentBroadcast stations and recording studios use tones from an audio generator to set volume controls on recorders and transmitters.AudiogramAudiometers, specialized audio frequency generators, are used when plotting audiograms to test a person’s hearing.
