Design of the C.A.L. Ultrasonic Generator for the Treatment of Meniere´s Disease

When the balance mechanism of the human ear is disturbed the patient suffers from attacks of vertigo and, as in the case of an affliction called Meniere´s disease, from a progressive loss of hearing. Several years ago it was discovered that ultrasound could beu sed for the effective treatment of this disease. An improved ultrasound generator for this purpose has been developed at the Commonwealth Acoustic Laboratories in Australia. This work gives design details for the applicator and the electronic circuitry. The equipment is completely transistorized and the applicator does not require a cooling system.
