Method and system for providing hearing assistance to a user

摘要

A method for providing hearing assistance to a user by capturing input audio signals; estimating a speech level of the input audio signals and an ambient noise level of the input audio signals; applying a gain model to the input audio signals to transform the input audio signals into filtered audio signals, wherein, for a each ambient noise level, the gain varies as a function of the speech level and wherein the function varies according to the ambient noise level changing the ratio of the gain at low speech levels and at high speech levels as a function of the ambient noise level; wirelessly transmitting the filtered audio signals to a receiver unit forming or being connected to a user hearing stimulator, the stimulator being worn at or in the user's ear; and stimulating the user's hearing by the stimulator according to audio signals supplied by the receiver unit.

1. A method for providing hearing assistance to a user, comprising:
capturing input audio signals by a microphone arrangement; estimating a speech level of the input audio signals and an ambient noise level of the input audio signals; applying a gain model to the input audio signals to transform the input audio signals into filtered audio signals, wherein, for a each ambient noise level, gain is varied as a function of the estimated speech level and wherein the function is varied according to the estimated ambient noise level in such a manner that the ratio of the gain at low speech levels and at high speech levels changing as a function of the estimated ambient noise level; transmitting the filtered audio signals by a transmission unit via a wireless audio link to a receiver unit comprising or connected to means for stimulating hearing of a user, the stimulating means being worn at or in a user's ear; and stimulating the user's hearing with the stimulating means according to the audio signals supplied by the receiver unit, wherein the receiver unit is connected to or integrated within a hearing aid and wherein the stimulation means is an output transducer of the hearing aid.
