A load compensating device, especially one for lifting appliances, includes a detector for detecting an overload or an underload and designed to cause actuation of the compensating device. Emulsions formed using this surfactant package are stable and have ratios of water to surfactant of at least about 3. The control circuitry includes logic applying one or more of a hearing profile of the user, a user preference related hearing, and environmental noise factors in processing the audio signals.
