What are the advantages of digital hearing aids?
The advent of digital hearing aids has met the growing demand for hearing aids for the hearing impaired, making the quality of life of hearing impaired people increasingly high. The emergence of digital hearing aids has completely changed the analog signal amplification method, which converts the electrical signal from the microphone into a digital signal, which is processed and converted into an analog signal to the receiver. So, what are the advantages of digital hearing aids compared to traditional hearing aids??
(1Intelligent suppression feedback howling: By continuously collecting the signal of the microphone, scouting the feedback sound, and sending an inverted signal before the howling occurs, to eliminate it without reducing the gain. It solves the annoying feedback whistle without reducing the high frequency gain that is important for speech resolution.
(2Intelligent sound control: the sound is divided into multiple frequency bands, each frequency band can be automatically adjusted according to the size of the input sound and the hearing loss of the patient, and the best sound output makes the hearing compensation more suitable for each hearing impaired person. Just like tailoring, listening to sound will be more natural and comfortable.
(3Intelligent noise reduction: Automatically distinguish between language and noise, so that only the voice is amplified and the noise is not amplified. In any case, it maintains a good signal-to-noise ratio and greatly improves the clarity of speech.
(4Sound Focus: A directional choice for the sound of the environment.
(5The all-digital programmable hearing aid completely changes the analog signal amplification method, which converts the electrical signal from the microphone into a digital signal, which is processed and converted into an analog signal to the receiver. Due to the digital signal processing, each channel can be arbitrarily adjusted linear amplification, linear compression, and nonlinear compression, and can be arbitrarily selected among multiple channels.
Although digital hearing aids have so many advantages, they should be fitted according to the comprehensive factors such as the degree of hearing loss, the nature of deafness, different types of hearing loss, and language resolution.
