Hearing aids are generally divided into analog hearing aids and digital hearing aids, analog hearing aids range in price from tens to hundreds of dollars, digital hearing aids range in price from 1,000 to 50,000 yuan.
1. Analog hearing aids: prices range from tens to hundreds of dollars, box hearing aids and simple behind-the-ear machines, is an analog circuit. Noisy, poor clarity, is linear amplification, all the sound all amplification, and has a simple volume control function. Long-term use of hearing will be secondary damage, this kind of hearing aid price is relatively cheap.
2. Digital hearing aids: prices from 1,000 to 50,000 yuan, the use of non-linear amplification technology, sound compression to reduce the effect of noise. The use of digital technology can be based on different hearing loss for targeted debugging, debugging, according to the need to automatically adjust the size of the volume. Can realize the small sound amplification, the middle sound appropriate amplification, loud compression. Let the wearer use more comfortable.
Digital hearing aids, there are in-the-ear machines, behind-the-ear machines. The better the sound quality, the more features, the more advanced technology, the price is relatively higher. Tens of thousands of dollars of hearing aids relative to the difference between a few thousand dollars is better to restore the true sound, better sound quality, more convenient operation, can effectively improve the quality of life.
With the development of science and technology, computer technology advances, more and more hearing aids are being developed every year, you can choose a hearing aid more suitable for your needs.
