Hong Kong Natural Sound Electronics HB15 In-Ear Hearing Device

Introduction

The digital hearing aid produced by our company is a high-tech product integrating acoustics, medicine and electronics. The system hardware is based on the all-digital chip, and the hearing aid function is realized through various software algorithms. The basic principle of digital hearing aids is to use electro-acoustic amplifiers to maximize the use of the user’s residual hearing, so that the hearing impaired patients can hear the amplified sound. Through the compensation and adjustment of hearing impairment in different frequency bands, individual hearing compensation can be satisfied.

Name:
In-ear hearing aid Model specifications are shown in Table 1.

FCC ID:PWK-HB15

Structure composition:
The HB 15 in-ear hearing aid is composed of earplugs, charging box, battery and host.

Working principle
The voice sensor converts the sound information into electrical signals, which are processed by the analog chip and then transmitted to the receiver and output through the sound tube. The signal processing adopts the principle of analog signal amplification.

The scope of application

After fitting, it can be used to compensate hearing for patients with aid conduction hearing loss.
