What is the difference between digital and analog hearing aids?

In jargon, it is the difference between a simulator and a digital machine. The simulator is a linear amplification sound. It is to amplify all the sounds together. If the hearing loss is not very heavy, wearing such a hearing aid for a long time is likely to damage the hearing. The more the wearer is, the lower the noise reduction function of the digital machine is than the simulator. The higher the price, the better the noise reduction function of the hearing aid can be debugged according to the audiogram by the computer. The hearing impaired can have any sound and can be debugged. The sound quality of the digital machine is better than that of the simulator..

Simulated hearing aids take linear amplification and take on all sounds1:1Zooming in, the gain is constant. It is suitable for patients with extremely severe hearing loss and is prone to residual hearing loss. Digital hearing aids are non-linear amplification, not1:1Amplification, the gain is not constant, large amplification for small sound, loud and small amplification, always within the narrow dynamic range of the patient’s hearing, making it more comfortable to wear, suitable for all hearing patients. Most of the previous hearing aids were analog lines. The analog hearing aids were standard unified amplification. They amplified the speech sound and amplified the external noise. For patients with sensorineural hearing loss, they may feel too noisy and uncomfortable. The hearing aid is to amplify the small sound and compress it into the patient’s comfort range so that the patient can hear and not feel uncomfortable. In addition, the fineness of the digital machine should be more precise.
