ABSTRACT:
The device has a microphone with a combined amplifier, filter and demodulator for detection of snoring noises. If the sleeper is found to be snoring, a control operates a tone generator, which drives a sound emitter via an amplifier for emitting acoustic signals. The individual signals have different frequency distributions and become increasingly unpleasant while the snoring phase lasts. By varying the frequency distribution of the signals, i.e. their pitch, contribution of harmonics, and time modulation, a habituation is prevented. In operation, the control preferably determines which signals have a strong and which signals a weak effect.
