The invention relates to a method for processing an acoustic input signal, preferably a speech signal, said method comprising the following steps: a) receiving a digital representation (S.sub.in) of an acoustic input signal, b) calculating at least one statistical parameter (P) of the digital representation (S.sub.in) of the acoustic input signal, c) calculating a compression ratio function (CR.sub.f) based—on a prescribed constant compression ratio (CR.sub.pr), said prescribed constant compression ratio (CR.sub.pr) uniformly mapping acoustic input signals of a selected magnitude to acoustic output signals of a selected magnitude, and—on at least one statistical parameter (P) calculated in step b), and d) applying the non-uniform compression ratio function (CR.sub.f) according to step c) on the digital representation (S.sub.in) of the acoustic input signal delivering a digital representation (S.sub.out) of an enhanced acoustic output signal.

Methods and systems for assessing insertion position of hearing instrument

A speaker of a hearing instrument generates a sound that includes a range of frequencies. Furthermore, a microphone of the hearing instrument measures an acoustic response to the sound. A processing system classifies, based on the acoustic response to the sound, a depth of insertion of an in-ear assembly of the hearing instrument into an ear canal of a user. Additionally, the processing system generates an indication based on the depth of insertion of the in-ear assembly of the hearing instrument into the ear canal of the user.

Combined HRTF for spatial audio plus hearing aid support and other enhancements

A HRTF used for 3D spatialized audio is combined with, e.g., by concatenation, additional settings to provide a more comfortable, accessible, and enjoyable experience for a listener such as a player of a computer game listening to audio through a headset. A single transfer function is thus created that includes the other settings, and once the transfer function is computed the run-time processing can be treated as a single combined transfer function rather than multiple separate stages, resulting in computational savings. The additional settings pertain to hearing aids normally worn by the listener as well as a room-related function specific to a particular listening venue.

20220386042 · 2022-12-01 ·

A method for processing an input audio signal includes using a first analytical filter bank to divide the input audio signal in a first frequency splitting process into a plurality of first frequency bands. The first frequency bands of a first subgroup are divided in a further frequency splitting process by a further analytical filter bank into a plurality of frequency subbands. The divided input audio signal is frequency-selectively processed or amplified. The divided and processed input audio signal is then combined again into an output audio signal. A prediction is applied to the first frequency bands of the first subgroup and/or the frequency subbands derived therefrom, to compensate for latency differences between the first frequency bands and the frequency subbands as a result of the or each further frequency splitting process. A device or hearing aid for carrying out the method is also provided.
