Broadband Hearing Aid – Broadband Hearing Aid?

Broadband hearing aid-Is a broadband hearing aid?

Bandwidth-enhanced hearing aids are showing more outstanding features. Broadband hearing aid, means that the frequency response is greater than8000HZHearing aid. Normal human ear can hear20HZ-20000HZThe sound is heard, but the hearing loss can only hear a part of the sound, and how much it depends depends on the bandwidth of the hearing aid. Whether listening to voice in quiet or noisy environments, music is still a spatial clue, and quality and quantity improvements are expected. Therefore, audibility, comprehension, listening pleasure, customer satisfaction, and affordability are very good. Not long ago, the frequency response curve of hearing aids was limited to5000To6000HzBetween, but the latest skills advance can now extend the bandwidth of high-end digital hearing aids to10,000Hzthat’s all.

This development is primarily due to three serious advances in hearing aids: signal processing enhancements, new in-ear receiver equipment and receiver skills improvements. Broadband hearing aid refers to the frequency compensation scale arrival8000 ~ 10000HzHearing aids, while the frequency of compensation for traditional hearing aids is mostly5000 ~ 6000HzThe frequency of the sound that the normal human ear can hear is20Hz-20000Hz. Hearing losers mostly need to wear hearing aids to compensate for the lack of frequency, and the frequency of hearing can be determined by the bandwidth of the hearing aid. The highest frequency compensation for wideband hearing aids introduced by Sea Voice10000HzCan make users hear more and more clearly. Broadband hearing aid features Speech clarity is as shown above:The high frequency area contains more verbal information, especially “f”,”s”,”th”Consonant sounds, these sub-tones play a crucial role in the clarity of speech. Broadband hearing aids can be excellently compensated.”6000 ~ 10000HzLoss of hearing, added to the audio of traditional hearing aids60%Greatly improved speech clarity. The sound quality is more natural, the human ear can hear the frequency at20 ~ 20000HzThe sound of the hearing aid, the wider the frequency compensation of the hearing aid, the hearing aid wearer can hear more ambient sound, more natural and comfortable. The study revealed that when children use extended high-frequency bandwidth hearing aids, their vocabulary acquisition can be significantly stronger. Children’s perceptions can progress with the addition of bandwidth, and vice versa, because limited bandwidth can have a suffocating effect on speech perception. Excellent music processing results show:Under the influence of speech signals, music signals and natural sound signals, the higher the frequency of wearing the hearing aids, the higher the sound resolution. This means that a wider high-frequency compensation can help the user to improve the sound of the sound. If you are a hearing-impaired child who needs speech practice and a person who needs to learn a different language, wearing a hearing aid with a wider high-frequency compensation, the meaning will be even more profound.!Super bandwidth and number of channels The number of channels in the hearing aid market in China has now become a major target for measuring the function of hearing aid products. Although the channel is a major concept, it has been proved that the super-frequency bandwidth is more important than the number of channels from the perspective of hearing compensation.! The following is a hearing of a hearing loss user. The user has a good low frequency and high frequency teaching. Let’s use hearing aidsAAnd hearing aidsBDon’t leave the user’s hearing:Hearing aidAHave6Channel high frequency high frequency wide8000HzHearing aidBHave12Channel high frequency bandwidth6000Hz. Everyone pays attention to the high-frequency part of the investigation(User at6000Hz-8000HzHave residual hearing)It is not difficult to see that although the hearing aidBHave12Channels, but can not fully compensate for hearing according to user hearing. Therefore, at a certain degree, the number of super-bandwidth channels is more important in the hearing aid fitting.

The frequency of music is wider than speech, because the frequency of traditional hearing aids is narrower. Many users simply abandon the need to wear hearing aids to enjoy music, and the higher frequency compensation of broadband hearing aids has brought more and more outstanding people. Sound quality. To further prove the benefits of broadband,Karlsen, Flynn And EnerothWait for the audiologist to leave the maximum bandwidth for wearing hearing aids6000Hz,8000HzAnd10000HzThe role of the comparison test. In the figure, after the same user wears a hearing aid with different bandwidth, the resolution of the sound signal is different.

Therefore, broadband hearing aids are very good in speech audibility, comprehension, listening pleasure, customer satisfaction and affordability. The study revealed that children with high-frequency hearing loss in the frequency compensation scale of hearing aids can significantly improve their vocabulary acquisition when using extended high-frequency bandwidth hearing aids. Children’s perceptions can progress with the addition of bandwidth, and vice versa, because limited bandwidth can have a suffocating effect on speech perception, resulting in a child’s speech recovery.
