Noise reduction technology for auditory compensation signal architecture

FIG. 2 is a schematic block diagram of an embodiment of the hearing compensation device of the present invention. As shown in Figure 2, users use their own hearing equipment 1 (various smart devices, such as smart phone applications APP with wireless (such as TWS) earphones) instead of using earphones dedicated to the hearing room for hearing in the hearing room. Measurement, so that the user can obtain the user's hearing threshold ( T _i ) information in various current real environments or real application environments (ie, quiet or noisy environments) instead of the audiology room, where i represents the measurement frequency. The measured T _i will be calculated and obtained through the auditory compensation prescription (prescription formula) 2 to obtain the compensation gain target curve G _i , and the types of auditory compensation prescription include hearing normalization (loudness normalization) and hearing equalization (loudness equalization), etc. Types of compensation prescriptions, for example, POGO, NAL-R, NAL-RP, DSL, DSL 5.0, POGO II, FIG6, NAL-NL1, NAL-NL2, IHAFF, LGOB, Aescu HRL-1...etc. have the same or The types of similar compensation prescriptions are not limited in this creation.

In one embodiment, the noise reduction technology 3 adopts an active noise cancellation (ANC) technology. For ease of description, the ANC technology is used as an example below, but in different embodiments, the same or similar noise reduction technology may be applicable, and the invention is not limited thereto. In this embodiment, the parameters of the filters 31, 32, 33 (such as FF, FB and SZ) can be set through the information of the "acoustic characteristics of the mechanism" and " G _i ", that is, the mean square error (mean- square error, MSE) method to set the filter parameters in the ANC technology, and then enable the ANC technology to perform gain compensation capabilities of different frequencies for the sound source transmitted by the transducer. In one embodiment, the filters 31, 32, and 33 can be feed-forward (FF) filters, feedback (FB) filters, and SZ filters, respectively, wherein the feed-forward (FF) filters receive the transducer (Ref .Mic) 200 electrical signal to eliminate external noise; the feedback (FB) filter receives the electrical signal from the transducer (Error.Mic) (that is, the transducer (Error.Mic) converts the in-ear noise into Electrical signal) to eliminate the noise in the ear; and the SZ filter receives the appropriate target curve (target curve) ( G _i ) to amplify the frequency of each frequency in the electrical signal (such as the signal source "S" in Figure 2). signal.

When G _i is obtained, the parameters required by the ANC technology are searched through optimization technology (for example, technology combined with genetic algorithm) or artificial intelligence technology to approach the target curve. In this embodiment, the structure of the Biquad filter is used to illustrate, and the following formula (1) can be obtained from the structure of the Biquad filter, that is, the filter is calculated by the above-mentioned optimization technology (or artificial intelligence technology) Parameters of " b ₀ , b ₁ ,..., b _N , a ₁ , ... ,a _M ".

Through the above method, the calculated correlation filter 31, 32, 33 parameters can be written into the hardware device, so that the auditory compensation device of the present invention can not only overcome the user leakage noise caused by environmental noise ( N' ) At the same time, it can also perform auditory compensation processing on the signal source ( S ) obtained by the transducer, so as to realize the problems that could not be solved in the hearing room in the past.

Fig. 3 is a schematic diagram of an embodiment of the hearing compensation of the hearing compensation device of the present invention. As shown in Figure 3, since the original speech signal (original speech) is processed through customized auditory compensation through the same or a single noise reduction circuit, the speech system is processed by noise reduction (such as ANC) technology Reduce the leakage noise and let the processed speech signal (processed speech) fall above the hearing threshold (hearing threshold) of the hearing loss. It should be noted that each person's hearing threshold is different, and this creation system can be applied to the hearing thresholds of various users, thereby producing an auditory compensation effect that has never been seen before.

Optimization technology integrates fitness function to search for parameters of noise reduction technology

How to quickly find out the current environmental characteristics of different users (especially the hearing-impaired and hearing-impaired) and give an appropriate target curve ( G _i ) is one of the key factors for improving the efficiency of the noise reduction system. In other words, it is very important to set the filter parameters in the noise reduction technology by considering the hearing threshold ( T _i ) information and the leakage noise ( N' ) characteristics of the hearing-impaired person at the same time.

In one embodiment, FIG. 4 is a flow chart of steps for searching the technical parameters of active noise reduction (ANC) of the hearing compensation device of the present invention; FIG. 5 is an embodiment of the arrangement of filter parameters of the hearing compensation device of the present invention schematic diagram. As shown in Figure 4, this creation uses optimization technology (for example, technology combined with genetic algorithm) with speech comprehension (STOI, SII, NCM, HASPI, ASR scores...etc.) or speech quality (PESQ, HASQI, SDR... etc.)-oriented functions are used as fitness functions to quickly find the appropriate ANC technical parameters. Through this creation, it can quickly consider the characteristics of environmental noise and the hearing condition of the user to provide personalized noise reduction and auditory compensation benefits. Detailed step-by-step instructions are shown below.

First, in step S1, M chromosomes are generated through random numbers, and the parameters required in the ANC technology are arranged in a fixed order in each chromosome, the concept of which is shown in FIG. 5 .

Next, in step S2, the chromosome parameter values in the M items will be brought into the ANC architecture to process the current test sentence. At this time, the M chromosomes can be scored by using speech comprehension and speech quality-oriented functions (eg, HASPI, HASQI). It should be noted that at this time, the hearing threshold ( T _i ) information of the user will also be considered simultaneously.

After that, in step S3, it is judged whether the current information has met the optimal solution (a threshold value will be set in this part) or the number of iterations has been completed?

If the optimal solution is not met, proceed to step S4 for subsequent chromosome selection. Proceed to step S5 afterwards, carry out mating (crossover), mutation (Mutation) etc. process, so as to generate a new group, for example, in this stage, "M+0.5M" chromosomes will be generated, and then in step S6, the chromosomes are selected according to the score calculated by the fitness function. In the new population, M items are still kept to search for the ANC parameters in the above steps, and then complete the search for ANC parameters in this part according to the set number of iterations.

Conversely, when the above process finds the optimal solution of the ANC parameters, then proceed to step S7, and directly transmit and store these ANC parameters to the user's earphones (such as TWS earphones) for auditory compensation and leakage noise elimination, thereby helping Users have better listening effect.

It should be noted that a ₁ , a ₂ , b ₀ , b ₁ , and b ₂ shown in FIG. 5 are parameters of the above-mentioned formula (1), but it is only for illustration, and the invention is not limited thereto.

Hybrid ANC technology

In addition, in the conventional technology, the user can adjust the level of the anti-noise level through buttons or environment sensing. In a crowded environment, you can quickly switch to the ambient sound mode to talk to people, or perceive the surrounding sounds to reduce the noise reduction coefficient to improve safety. Active noise canceling headphones are headphones that can eliminate unpleasant sounds (ie, noise) around them through active noise control (ANC). Human voices, car horns, etc. are all high-frequency. When using headphones, you may worry that you cannot hear other people’s voices. When crossing the road, you must keep your hearing sensitive for safety. Therefore, the most urgent need for most users is to block low-frequency noise. The principle is to use the noise reduction system to generate sound waves opposite to the external noise to neutralize the noise, thereby achieving the effect of noise reduction.

If the ambient low-frequency noise (about 20 to 200Hz) that can be heard by the human ear is detected through the microphone in the earphone, then the noise signal is sent to the control circuit, allowing the control circuit to perform real-time The noise can be canceled out by transmitting the sound wave with the opposite phase and the same amplitude as the noise through the loudspeaker. The noise reduction effect is achieved through the hardware mechanism. The interior consists of a pickup (responsible for listening to and detecting external sounds that cannot be isolated by physical structures), a noise reduction processor (generating a 180° opposite sound wave that opposes the noise), and a speaker ( The reverse sound wave produced by the noise reducer will be transmitted to the speaker of the earphone together with the normal music to complete the noise reduction. However, the current filter parameters used by ANC are not designed in consideration of hearing loss, which will result in the inability to achieve the best performance between noise cancellation and compensation units. In other words, if the intersection of two partial optimization parameters, such as noise cancellation and hearing compensation, can be considered at the same time, it will allow hearing loss people to have better listening benefits in real application situations.
