The principle and structure of hearing aids

Linear circuit hearing aids. Most linear circuit hearing aids have a volume switch that can be used to adjust the volume. In a quiet environment, linear hearing aids help to hear soft sounds, and the linear circuit amplifies all the sounds at the same time, so it is more suitable for people who live in a quieter home. For those who often need to enter and leave different environments, or the environment is very noisy, you may need to consider other circuits of hearing aids, such as digital hearing aids.

Compression circuit hearing aid. If you are in an environment with a soft and loud sound, the compression circuit can expand the soft sound and maintain the loud sound in your personal comfort. Because it gives a soft sound and a large sound with different levels of amplification. Some compression circuits can separately handle the amplification of different frequencies, which helps the user to better understand the words in the conversation, and because of the compression circuit, these adjustments can be made automatically, and the user does not need to adjust the volume switch frequently.

Digital programming hearing aids. The circuit inside the digital hearing aid is like a small computer. We can use its parameters to perform the adjustments we have to make. When you choose the new hearing aid center, the hearing specialist will check your hearing test results, discuss with you where you use the most hearing aids, your hobbies, and your hearing requirements. The hearing specialist then enters your hearing data into a professional hearing aid fitting software, and the software calculates the hearing solution that best suits you. The benefit of digitally programmed hearing aids is that if your hearing situation changes, the parameters of the hearing aid can be reset according to your new hearing situation. Even when your personal hearing preferences change, we can also make the appropriate settings. For example, if you find that reading newspapers in the morning, the sound of flipping the newspapers is too loud, we can adjust the parameters of your hearing aids through software. The biggest advantage of digital programming hearing aids is the flexibility of sound adjustment, which guarantees the best sound quality, and can be customized according to the needs and preferences of individual users to help patients to ensure the quality of listening in different listening environments.
