Description

The hearing devices of optional aware space positioning with sound source

Technical field

This subject application is related to a kind of hearing devices and its application method.

Summary of the invention

The new hearing devices system of one kind disclosed herein.The hearing devices system has hearing devices and control device, control Device processed allows user to select the perceived direction for being sent to the arrival for the voice signal of hearing devices selected.

Hearing devices for example can be following kind of earphone, earpiece, receiver, ear defenders, ear muff etc.: ear hook, ear On interior, ear, after earmuff, neck, headgear, the helmet etc..

Hearing devices can be binaural hearing aid.The hearing aid of binaural hearing aid can be with Types Below: BTE, RIE, ITE, ITC, CIC etc..

Control device can be computer, and such as PC (such as fixed PC, portable PC etc.) or hand-held device are (all Such as tablet PC, such as IPAD), smart phone (such as Iphone, Android phone, windows mobile phone etc.), etc..

Hearing impaired individual often experiences at least two different problems:

(1) hearing loss is the increase of hearing threshold level, and

(2) compared with normal good hearing individual, understand the loss of the ability of voice in noise.For most of impaired hearing diseases For people, even if restoring the audibility of introducing sound by amplifying, the performance in noise in the test of speech understanding degree is also poor In normal good hearing personage.Speech reception threshold (SRT) is the performance measures to the loss for understanding speech capability, and is defined For in order to which 50% correct speech recognition, the signal-to-noise ratio required in the signal of presentation are realized in hearing test in noise.

In order to compensate for hearing loss, present digital deaf-aid usually using multichannel and compressed signal processing be hearing by Damage individual restores the audibility of sound.In this way, being heard by the voice prompting that do not heard before making to improve listening for patient Power ability.

But understand voice in noise, include the voice in the environment of multiple spokesman, the loss of ability be still The major issue of most of hearing aid users.

In order to increase the signal-to-noise ratio for the voice for being originated from specific spokesman, a tool available to hearing aid user is to quilt The spokesman of consideration is equipped with microphone (being frequently referred to as pairing microphone), and microphone picks up the language from considered spokesman Sound causes voice to have high s/n ratio due to the degree of approach of microphone and spokesman.Pairing microphone converts speech into correspondence The audio signal with high s/n ratio preferably wirelessly, be sent to helping for hearing compensation and by signal Listen device.In this way, voice signal is supplied to user with the signal-to-noise ratio of the SRT much higher than considered user.

Increase the spokesman wished to listen to from hearing aid user, such as in public (such as in church, auditorium, play Institute, movie theatre etc.) or pass through public address system (such as at the train station, airport, shopping center etc.) to many people speech Spokesman voice signal-to-noise ratio another method be picked up in a manner of through magnetic using pick-up coil generation audio letter Number, such as pass through phone, FM system (there is neck ring) and inductive loop system (also referred to as " hearing ring ").In this way, with remote high Sound is sent to hearing aid in the signal-to-noise ratio of the SRT of hearing aid user.

But wish to listen to one simultaneously in the wherein user of traditional binaural hearing aid or another seed type hearing devices In the case where above above-mentioned monaural audio signal source, user is, it can be seen that be difficult to a signal source and another signal source region It separates.

8,208,642 B2 of US discloses a kind of method and apparatus for binaural hearing aid, wherein in order to listen to list The benefit that binaural listening is obtained when ear signal source presents to two ears of the user of wearing dual-earpiece hearing aid and comes from single monaural The sound of signal source.The sound for being presented to an ear is phase-shifted relative to the sound for being presented to another ear, and is added Ground, the sound for being presented to an ear can be set to different grades relative to the sound for being presented to another ear.This Sample, the inclined side property and volume of monaural signal are controlled.For example, be benefited to be received from the ears of call, it can be to two Telephone signal is presented in ear, for example, pass through in the case where no phone is unfavorable for it (even if in correct phase and grade) by The sounding of caller passes to ear, suitably by the sound laterality of the sounding of caller.

Hearing devices usually will reproduce sound in the way of the sound source of localization within head by user's perception.The sound It is said to be by internalization rather than by externalization.

When referring to " hearing phonetic problem in noise ", complaint universal for hearing aid user is to be difficult to follow just In any sound said, even if signal-to-noise ratio is enough to provide the speech understanding degree of requirement.To the fact that significant contribution person be to help Device is listened to reproduce the sound field of internalization.Increase the cognition load of hearing aid user in this way, and will lead to auditory fatigue, eventually leads to User removes hearing aid (multiple).

Therefore, it is necessary to have the new hearing devices system of the sound source localization improved, that is, it is required to relative to hearing The wearers of the hearing devices of apparatus system informs the new of the direction of each sound source of perception and the spatial information of potential range Hearing devices system.

Personnel with normal good hearing can also experience externalization and localization of sound source raising when using hearing devices Benefit, thus pass through externalization sound source enjoy reproduce sound.

A kind of new method described below, in the acoustic environment of people, by auditory localization in desired aware space direction Or in position.

New method can distinguish the sound in different spaces direction or position using the auditory system of people in acoustic environment The ability in source, and be absorbed in the one or more of selection and be spatially separating the ability of sound source.

In addition, also disclosing a kind of new hearing devices system using new method.

According to new method, in the acoustic environment of people, the sound in different spatial or direction is located according to person sensitive Signal from different sound sources is presented to the ear of personnel by the mode in source.In this way, the binaural signal of the auditory system using people Handle to improve the ability of signal of user's separation from different sound sources and concentrate on his or her listening the phase in sound source It hopes the ability of sound source, or listens to and understand more than one sound source simultaneously.

Further it has been found that if voice signal, i.e. phase shift relative to each other is presented with reverse phase in two ears of people 180 degree then perceives the specific direction reached less than signal；But many user's discoveries are easy with the voice signal that reverse phase is presented From other Sound seperations and understanding.Phase shift by range at 150 degree to 210 degree can obtain this effect.

People are detected and the sound source in localization three-dimensional space by the ears sound localization ability of people.

Input to hearing includes two signals, that is, the acoustic pressure at each ear-drum, hereinafter referred to as ears voice signal. Therefore, if accurately reproduced at ear-drum by giving the acoustic pressure at the ear-drum that space sound field generates originally, people's listens Feel system cannot distinguish the sound of reproduction and the actual sound generated by space sound field itself.

The transmission of the sound wave of the sound source of assigned direction and distance is located in from the left and right ear relative to audience according to two Transmitting function (one is used for left ear, and one is used for auris dextra) describes comprising any linear distortion, such as between coloring, ear when Between difference and ear between spectral difference.This collection of two transmitting functions (one is used for left ear, and one is used for auris dextra) is collectively referred to as head correlation biography Send function (HRTF).Each transmitting function of HRTF is defined as through the specified point in association ear canal or close to association ear canal The acoustic pressure p (p in left ear canal that generates of plane wave_L, p in right ear canal_R) ratio relative to reference value.The reference value generally selected Be audience not in case, the acoustic pressure p that the original plane wave by position at the middle of head generates_l。

HRTF includes all information related with the sound for being transferred to audience's ear, including around ear diffraction, from shoulder The reflection of wing, the reflection in ear canal etc., and therefore, HRTF changes with individual.

For convenience, one of transfer function of HRTF is also referred to as HRTF below.

HRTF changes with sound source relative to direction and the distance of audience's ear.It can be to any direction and range measurement HRTF, and simulate HRTF, such as by electronically, such as pass through filter.If by such filter insertion audio letter The signal road between loudspeaker (for emitting sound to each ear of audience) that number source (such as microphone) and audience wear Diameter, then listening numerous generals to obtain such perception, i.e., the sound of loudspeaker generation is from quilt because of the true reappearance of acoustic pressure in ear It is positioned through the distance of the transmitting function restriction of the filter of the considered HRTF of simulation and the sound source in direction.

In version space encoded information, several good effects are led to by the ears processing of brain, that is, the signal of raising Source separation；The arrival direction (DOA) of raising is estimated；And the depth/distance perception improved.

How the auditory system of not exclusively understanding people extracts the information relative to distance and direction to sound source, but knows Road, the auditory system of people use many prompts in this determination.There are spectrum prompt, reverberation prompt, interaural difference in these prompts (ITD), rank difference (ILD) between phase difference (IPD) and ear between ear.

Most important prompt is rank difference (ILD) between interaural difference (ITD) and ear in ears processing.ITD be due to From sound source to the distance difference of two ears.The prompt is substantially useful until about 1.5kHz, be more than the frequency auditory system just not ITD prompt is solved again.

Rank difference is diffraction as a result, and being determined by ear compared to the relative position of sound source.The prompt is being more than It works when 2kHz, but auditory system is equally sensitive to the variation in ILD on entire frequency spectrum.

It has been shown that impaired hearing main body mainly prompts to benefit from ITD, because hearing loss is tended in lower frequency It is less serious.

Orientation transmitting function is head correlation transmitting function or transmits function to the head correlation of input signal addition directional cues Can approximation so that listening to the person sensitive of ears voice signal to from sound based on the ears filter with orientation transmitting function The sound of source transmitting resides in the direction that prompt limits.
