As an important hearing aid device, hearing aids can help people with hearing impairments regain clear sound. So, are you also curious about how hearing aids work? The following is the working principle of hearing aids.
1) Sound Collection: Hearing aids are equipped with microphones, which function similarly to small recording devices and can sensitively capture various sounds in the surrounding environment, such as conversations, traffic noise, etc. Regardless of whether the sound comes from the front, back, or side, it can be effectively collected.
2) Signal conversion: The collected sound signal is transmitted to an amplifier, where it is converted from its original acoustic energy form to electrical energy form for subsequent processing.
3) Sound amplification: The amplifier amplifies the electrical signal according to the degree of hearing loss of the wearer. The frequency range with severe hearing loss has a relatively higher amplification level, ensuring that sounds of different frequencies can be adjusted to the appropriate intensity.
4) Signal output: The amplified electrical signal is converted into echo energy and transmitted to the ear through a speaker (receiver), allowing the wearer to hear clear and appropriate sound, helping to improve their hearing condition.
Hearing aids are of great significance to the hearing-impaired population,serving as a key bridge connecting them to the world of sound. However, inferior hearing aids are like “killers” in the dark, with outdated technology and distorted sound. Long term use can worsen hearing damage. So choosing a high-quality hearing aid is crucial.
