What is the Difference between Analog Hearing Aids and Digital Hearing Aids?
(1) From the movement, the analog hearing aid is composed of a large number of electronic components, namely Cao Yong analog line. The core is an analog amplifier and the signal processing is analog. The movement of the digital hearing aid is a small computer chip, which is equivalent to a small computer. It uses a logic circuit, that is, it performs some calculation on the input signal and outputs it. The signal processing is digital.
(2)In terms of audiology, traditional hearing aids are mostly linearly amplified, that is, the sounds of light, medium and heavy sounds are equally amplified, resulting in audible audible, loud and uncomfortable hearing, severe damage to the ears, and increased hearing loss. Digital hearing aids are non-linearly amplified, which sounds clear and comfortable, and helps protect hearing.
(3) Functionally, digital hearing aids also have the advantage that many analog hearing aids do not have. Digital hearing aids are extremely fast, like a detector, that automatically changes with the environment. It automatically analyzes the environment. If it is in a noisy environment, it will play the automatic noise reduction function, which will amplify the speech and reduce the noise, thus improving the understanding of the language and sounding comfortable.
(4) Digital hearing aids also have the advantages of small size, long battery life, high stability, and strong anti-interference ability. In short, digital hearing aids have high language clarity, high sound quality and comfortable listening. More and more people choose digital hearing aids, which is very effective.
