A b s t r a c t In a method and apparatus for the generation and transmission of complex pressure surges to the fluid system of the inner ear, this fluid system comprising an outer fluid chamber (perilymphatic space) provided with inlet and outlet, which entirely surrounds an inner fluid chamber (endolymphatic space), the fluid volume therein regulating the hearing ability of the ear in order, through intermittent com- pression of said inner chamber, to reduce any impairment of the hearing which may exist due to expansion of said chamber caused by too large a volume of fluid in said inner chamber, reproducible pressure pulses or surges are produced, consisting of a first pressure component (a) having varying pressure oscil- lations, and a second component (b) superimposed on said first component (a) and having a predeterminable overpressure, said first component (a), by means of rapidly repeated pressure variations, substantially blocking the passage of fluid from the outer fluid chamber, in addition to which the said component (b) via the original volume of fluid thus retained in the outer chamber, intermittently compresses the inner fluid chamber in order to regulate the fluid volume therein.
