Abstract: A behavior shaping device is disclosed for eliminating nocturnal sounds, such as snoring. The device comprises the generally well-known microphone amplifier and alarm means, with the alarm means being actuated when the input level is above a predetermined level. As part of the behavior shaping technique, a counter is provided to indicate the number of times the alarm is sounded in a predetermined time period to permit the lowering of the threshold level as the number of times the alarm is sounded decreases. Memory means are provided to store the counts generated in accordance with the time periods and to provide a display of the respective counts registered.
