Definitions
- the invention relates to a method for operating a hearing aid with the features of the preamble of the claim 1 and a hearing aid with the features of the preamble of Claim 5.
- Hearing aids which are wearable on the head are known as prior art, what special hearing programs to suppress Have noise, certain by activating a filter Frequency components are damped. As a result, a Improvement in general noise levels achieved which, however, is not sufficient for many applications.
- a hearing aid with at least one is known from EP 577 441 A2 Input converter of a signal processing unit and one Output converter.
- the signal processing unit comprises an A / D converter at the input, several parallel signal channels with one filter, one analysis element and one Adaptation element and at the output a D / A converter.
- the signal processing unit enables recognition and lifting of speech signals.
- the signal analysis is based on measurements the amplitude, frequency, duration and frequency changes of a signal.
- this hearing aid includes a device for measuring the strength of a signal in each individual frequency selection channel and to influence the channels with each other in the sense of suppression from weak signal channels to the advantage of strong ones Signal channels.
- WO 91/03042 describes a method and a device for distinguishing known from speech and interference signals. Doing so divides the input signal into several band-limited partial signals, each of which has at least two harmonic frequencies of the speech signal contains. It will be the envelopes of the partial signals as well as the synchronism between the envelopes determined. Depending on the value of the determined synchronism the partial signals are further processed.
- the disadvantage of this method is the high level associated with it Computational effort.
- a multi-channel hearing aid emerges from US Pat. No. 4,852,175. in which the individual channels independently on the Existence of noise is investigated. Will in one Channel noise is detected, so there is a reduction in Reinforcement for this channel. The level of noise in one Channel is determined based on an amplitude histogram.
- the invention has for its object a hearing aid, such as a hearing aid that can be worn on the head or an implantable hearing aid as well as a method for operating a hearing aid create an improvement in speech intelligibility in enable a variety of listening situations.
- a hearing aid such as a hearing aid that can be worn on the head or an implantable hearing aid as well as a method for operating a hearing aid create an improvement in speech intelligibility in enable a variety of listening situations.
- the task becomes for the procedure for operating a hearing aid by the features of the characterizing part of the claim 1 in conjunction with the features of the preamble solved.
- Advantageous embodiments of the method are realized by subclaims 2 -8.
- the task is characterized by the characteristics of the characteristic part of claim 9 solved with the features of the preamble.
- the hearing aid according to the invention has an analysis element for Detection of speech information in which the filter element of the Hearing aid split partial signals.
- the filter element of the Hearing aid split partial signals.
- the mean and the course of the envelope determined. If the level peaks, the amount exceeds of the envelope the amount of the mean.
- Such one Excess can be used as a criterion for the existence of a Level peak are used, so that this in the analysis of the partial signal the presence of speech information becomes detectable. Thereupon the considered partial signal be raised to face the detected speech information to amplify low-level noise.
- the split partial signals have the lowest possible frequency range.
- the analysis element advantageously comprises several analysis programs for the detection of different speech information and speech patterns.
- an analysis program for the detection of sudden level peaks serve. Such peaks are often speech information, the level of which is the constant and low level Noise exceeds.
- the hearing aid according to the invention enables any short-term and only occasionally occurring Detect and specifically raise voice information.
- the control process is ended immediately when from Analysis element determines that no speech information there is more. This avoids that after the voice information re-emerging noise was also raised becomes.
- an analysis is carried out first for the detection of speech information in the partial signals, by splitting the total signal in a filter element be won.
- the respective partial signal is raised and thus the Speech intelligibility of the detected speech information improved.
- Speech information in the partial signals by detection determined from level peaks ("bursts"). When such occurs Level peaks are highly likely to be speech information in front of the low noise level (e.g. background noise).
- the respective partial signal can be used in further process variants in its signal course with mathematical methods and characteristic values be analyzed in the manner of a curve discussion.
- the analysis of the partial signals according to the invention can be arbitrary short time intervals take place, even to individual only briefly occurring language elements (e.g. vowels, sibilants, consonants etc.) to be detected and practically with immediate effect and only short settling times to improve the Increase speech intelligibility.
- a spoken word is just a single letter starting with matches a certain language pattern, especially highlighted while the other letters and syllables transmitted unreinforced or with less gain.
- the method according to the invention thus enables selective Improve speech intelligibility.
- Control and regulation jumps within a very short time Settling times ( ⁇ than 2 ms) and switches within equally short decay times if there is no more language is detected.
- the analysis element 7 the partial signals of the individual channels 11, 11 ', 11 "for the presence of language. If A detection of speech is made over the connection between analysis element 7 and adaptation device 8 the respective Sub-signal 12 raised in the adaptation element 8 (increased), to improve speech intelligibility.
- the signal processing element 9 are the partially raised partial signals processed (e.g. by AGC circuits). After a Merging of the partial signals 12 and a D / A conversion in D / A converter 10, the overall signal with improved speech intelligibility fed to the listener 3.
- FIG. 2 is a schematic illustration and shows for reasons clarity, a relatively long lasting level increase.
- the method according to the invention also enables Detection of short-term level peaks (not shown).
- the course of the partial signal 12 can now be mathematical Methods and parameters e.g. with those from the curve discussion known methods can be assessed in the analysis element 7. there can have minima, maxima and pole positions as well as first or higher Derivatives are calculated and based on the results.
- minima, maxima and pole positions as well as first or higher Derivatives are calculated and based on the results.
- the analysis of the partial signal 12 of the respective channel 11, 11 ', 11 '' serves for the detection of speech, since only when it is present of speech information, the raising of the invention respective partial signal 12 in the considered analysis period should take place in order to avoid that also a noise level is raised.
- FIG. 2 shows the analysis of the profile of the partial signal 12 in the analysis element 7 the mean 13 and the (schematic shown) envelope 14 of the partial signal 12 is formed.
- the amount of the envelope 14 increases to the value A, as a result of which the coverage area 15 between the envelope 14 and the mean value 13 increases. It can be assumed that the value A is above a limit value X between the value B and the value A.
- the increase occurs with the shortest possible settling time of less than 2 ms after t 1 and is ended after t 2 with the shortest possible settling time of likewise less than 2 ms.
- the method according to the invention thus reacts briefly and spontaneously to the speech information present between the times t 1 and t 2 in the partial signal 12 and raises the partial signal 12 accordingly between the times t 1 and t 2 .
- the level increase (at t 1) and level drop (at t 2 ) can also follow one another briefly, as a result of which the partial signal 12 can be raised and lowered again practically without delay due to the particularly short settling / decay times (not shown).
