Abstract (en)
[origin: EP1843632A2] The aid has a mixer (15) provided with nonlinear characteristics and transposed in a frequency range above an audio frequency range. An oscillator (13) produces a carrier wave that is supplied to a sound emitter (4`), where a signaling rate reduced by reflection and scattering on the sound emitter from a microphone (3`) is highly different due to original sound signal. The sound signal converted into an electrical signal is processed and is not supplied to the sound emitter.
