Abstract
Squeal in a hearing aid is inhibited by a circuit that monitors battery voltage. In response to sensed low battery voltage, a cutoff circuit disables the hearing aid audio amplifier. Also in response to low battery voltage, a crowbar circuit loads the hearing aid battery with a loading circuit element.
