A new hearing device system is disclosed herein. The hearing device system has a hearing device and a control device that allows a user to select perceived directions of arrival of selected sound signals transmitted to the hearing device.
Description
Technical field
This subject application relates to a kind of hearing devices and using method thereof.
Summary of the invention
A kind of new hearing devices system is disclosed here.This hearing devices system has hearing devices and control device, control device allow user select to send to hearing devices by the perceived direction of the arrival of voice signal selected.
Hearing devices can be such as with the earphone of Types Below, receiver, receiver, ear defenders, ear muff etc.: ear hooks, in ear, on ear, after earmuff, neck, headgear, helmet etc.
Hearing devices can be binaural hearing aid.The hearing aids of binaural hearing aid can be with Types Below: BTE, RIE, ITE, ITC, CIC etc.
Control device can be computer, such as PC (such as fixing PC, portable PC etc.), or hand-held device (such as dull and stereotyped PC, such as IPAD etc.), 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, it is the increase of hearing threshold level, and
(2) compared with normal good hearing individuality, the loss of the ability of voice in noise is understood.For most of impaired hearing patient, even if by amplifying the audibility recovering to introduce sound, the performance in noise in the test of speech understanding degree is also worse than normal good hearing personage.Speech reception threshold (SRT) is the performance measures to the loss understanding speech capability, and is defined as, in order to realize the correct speech recognition of 50% in hearing test in noise, the signal to noise ratio required in the signal presented.
In order to compensate hearing loss, present digital deaf-aid uses multichannel and compressed signal to be treated to the audibility of hearing impaired individual recovery sound usually.Like this, hear by inaudible voice message before making the Listening Ability of Ethnic improving patient.
But, understand voice in noise, include the voice in the environment of multiple spokesman, the loss of ability remain the major issue of most of hearing aid user.
In order to increase the signal to noise ratio of the voice being derived from specific spokesman, to hearing aid user can an instrument be equipped with microphone (be often called pairing microphone) to the spokesman be considered, microphone pickup is from the voice of the spokesman be considered, due to the degree of approach of microphone and spokesman, voice are caused to have high s/n ratio.Speech conversion is the corresponding audio signal with high s/n ratio by pairing microphone, and by signal, preferably by wireless mode, sends to the hearing aids for hearing compensation.Like this, with the signal to noise ratio of the SRT far above the user be considered, voice signal is supplied to user.
The spokesman listened to is wished in increase from hearing aid user, (such as in church, auditorium, theater, movie theatre etc.) or the another kind of method of the signal to noise ratio of the voice of spokesman of being given a lecture to a lot of people by Public Address system (such as at the train station, airport, shopping center etc.) use pick-up coil such as in public, to be picked up the audio signal of generation by magnetic mode, such as by phone, FM system (there is neck ring) and inductive loop system (also referred to as " hearing ring ").Like this, with the signal to noise ratio of the SRT far above hearing aid user, sound is sent to hearing aids.
But when the user of traditional binaural hearing aid or another kind of type hearing devices wishes to listen to more than one above-mentioned monaural audio signal source wherein, user can find simultaneously, be difficult to a signal source and another signal source to distinguish.
US 8,208,642 B2 discloses a kind of method and apparatus for binaural hearing aid, and wherein in order to obtain the benefit of binaural listening when listening to monaural signal source, two ears to the user of wearing dual-earpiece hearing aids present the sound from single monaural signal source.The sound of presenting to an ear is phase-shifted relative to the sound of presenting to another ear, and additionally, the sound of presenting to an ear can be set to different grades relative to the sound of presenting to another ear.Like this, the inclined side property of monaural signal and volume are controlled.Such as, be benefited to receive from the ears of call, telephone signal can be presented to two ears, such as when not having phone to be unfavorable for it (even if in correct phase place and grade) by the sounding of caller is passed to ear, with suitably by the sound laterality of the sounding of caller.
Hearing devices usually will the mode producing sound of sound source of localization within head according to user awareness.This sound is said into by internalization instead of by externalization.
When mentioning " in noise hearing phonetic problem ", complaint general for hearing aid user is difficult to follow any sound said, even if signal to noise ratio is enough to the speech understanding degree providing requirement.It is the sound field of hearing aids reproduction internalization to the significant contribution person of this fact.The cognitive load of such increase hearing aid user, and can auditory fatigue be caused, finally cause user to remove hearing aids (multiple).
Therefore, need the new hearing devices system of the sound source localization with raising, namely need the new hearing devices system can informing the direction of each sound source of perception and the spatial information of potential range relative to the wearer of the hearing devices of hearing devices system.
The personnel with normal good hearing also can experience externalization of sound source raising and the benefit of localization when using hearing devices, thus are enjoyed the sound reproduced by externalization sound source.
A kind of new method is disclosed below, in the acoustic environment of people, by auditory localization in the aware space direction expected or position.
New method utilizes the auditory system of people can distinguish the ability of the sound source being in different spaces direction or position in acoustic environment, and is absorbed in the ability of one or more spaces separating sound-source of selection.
In addition, a kind of new hearing devices system using new method is also disclosed.
According to new method, in the acoustic environment of people, the signal from different sound source is presented to the ear of personnel by the mode being positioned at the sound source in different spatial or direction according to person sensitive.Like this, utilize the binaural signal process of the auditory system of people to be separated from the ability of the signal of different sound source and by his or her ability of listening to the expectation sound source concentrated in sound source to improve user, or listen to simultaneously and understand more than one sound source.
In addition have been found that if present voice signal with anti-phase in two ears of people, i.e. relative to each other phase shift 180 degree, then the specific direction that arrives less than signal of perception; But a lot of user finds with the anti-phase voice signal presented easily from other Sound seperation and understanding.This effect can be obtained the phase shift of 150 degree to 210 degree by scope.
People are detected and the sound source in localization three dimensions by the ears sound localization ability of people.
Two signals are comprised, namely the acoustic pressure at each ear-drum place, hereinafter referred to binaural sound tone signal to the input of hearing.Therefore, if originally reproduced exactly at ear-drum place by the acoustic pressure at the ear-drum place of given space sound field generation, so the auditory system of people just can not distinguish the sound of reproduction and the actual sound produced by space sound field itself.
Be positioned at the transmission of the sound wave of the sound source of assigned direction and distance (one for left ear according to two transmitting functions from the left and right ear relative to audience, one for auris dextra) describe, it comprises any linear distortion, such as painted, spectral difference between interaural difference and ear.This set of two transmitting functions (for left ear, for auris dextra) is called that head is correlated with transmitting function (HRTF).Each transmitting function of HRTF is defined as acoustic pressure p by producing in association duct or near the plane wave of the specified point of association duct (p in left duct
l, p in right ear canal
r) relative to the ratio of reference value.The reference value of usual selection is audience not in case, originally by the acoustic pressure p of the plane wave generation of position at head middle place
l.
HRTF comprises the full detail relevant with the sound being transferred to audience's ear, comprises the diffraction around ear, from the reflection of shoulder, reflection duct etc., and therefore, and HRTF is with individual and change.
For simplicity, below by one of transfer function of HRTF also referred to as HRTF.
HRTF along with sound source relative to the direction of audience's ear and distance and change.To any direction and range measurement HRTF, and HRTF can be simulated, such as, by electronics mode, such as, pass through filter.If the signal path between the loud speaker (launching sound for each ear to audience) that such filter insertion audio signal source (such as microphone) and audience are worn, so because of the true reappearance of acoustic pressure in ear, numerous generals are listened to obtain such perception, the sound source in the Distance geometry direction that the sound source that namely loud speaker produces limits from the transmitting function being positioned in the filter by simulating considered HRTF.
When version space coded message, cause some good effects by the ears process of brain, that is, the source separation of raising; The arrival direction (DOA) improved is estimated; And the depth/distance perception improved.
How the auditory system of incomplete understanding people extracts the information relative to the Distance geometry direction to sound source, but knows, the auditory system of people uses a lot of prompting in this determines.Spectrum prompting, reverberation prompting, interaural difference (ITD), rank difference (ILD) between phase difference (IPD) and ear between ear is had in these promptings.
In ears process, most important prompting is rank difference (ILD) between interaural difference (ITD) and ear.ITD is due to from sound source to the distance difference of two ears.This prompting, until approximately 1.5kHz is substantially useful, exceedes this frequency auditory system and just no longer solves ITD prompting.
Rank difference is the result of diffraction, and is determined by the relative position that ear compares sound source.This prompting is working more than during 2kHz, but auditory system is responsive equally to the change in ILD on whole frequency spectrum.
Show, impaired hearing main body is mainly benefited, because hearing loss is tended to not too serious in lower frequency from ITD prompting.
Directed transmitting function is that head is correlated with transmitting function or to be correlated with the approximate of transmitting function to the head that input signal adds directional cues, and the person sensitive making to listen to binaural sound tone signal based on the ears filter with directed transmitting function resides in the direction that prompting limits to the sound from source emission.
