How to understand the simulator and digital machine in the hearing aid?
Hearing aids can be divided into analog and digital machines according to the amplification principle.
Simulator It is a linear amplification circuit that amplifies all sound signals directly through the amplifier. Although it is possible to control the volume, but it does not distinguish between speech signals and noise, the listening effect is not good, and the listening experience is not very comfortable.
Digital machine It is a variability amplifier circuit that accurately amplifies speech signals through frequency bands, channels, automatic noise control, automatic feedback management, output, compression, peak movement, etc., while reducing noise interference and improving speech. Comprehension and comfort of listening.
Therefore, the use value and listening comfort of the digital machine is far superior to the simulator. With the development of hearing aids, simulators should be phased out.
