<p>Hearing aid, comprising at least one microwave generator (9) which receives an electrical signal from, for example, a microphone (27) and generates a frequency-modulated electrical signal composed of bursts, the burst frequency depending on the sounds picked up by the microphone, which frequency-modulated signal is fed to a radiator (25, 26) which generates microwave radiation (28) made up of bursts, at least the radiator (25, 26) of the hearing aid being situated in the ear canal (11) of a hearing organ and the microwave generator (9) being designed in such a way that the burst frequencies are at least virtually equal to the sound frequencies of the sounds picked up by the microphone.</p> |
