What do the parameters of hearing AIDS represent?
Channel: Different frequency bands of sound are adjusted separately
Maximum gain: The maximum ability of a hearing aid to amplify sound
Maximum sound pressure level: The maximum output capacity of a hearing aid
Equivalent input noise: The internal noise generated by the operation of a hearing aid
Frequency response range: The range of sound frequencies that a hearing aid can handle
Harmonic distortion: The frequency doubling interference generated when amplifying sound
Battery life: The time a hearing aid can be used continuously after being fully charged
Time delay: The "time difference" of sound heard by the ears
Battery current: It reflects the power consumption level of the hearing aid during operation
Protection grade: The ability of hearing AIDS to be dust-proof and water-proof
How to read the parameters?
Number of channels: The more channels there are, the more precisely it can adapt to different hearing problems
Full-range gain (FOG) : The larger the value, the stronger the ability to amplify sound
Maximum sound pressure level (SSPL) : The larger the value, the greater the maximum output power of the hearing aid
Total harmonic distortion (THD) and equivalent input noise (EIN) : Important indicators for measuring the sound quality of hearing AIDS. The smaller the value, the better the quality of the hearing aid
Frequency response range: The range of sounds that the human ear commonly hears is 200-8000Hz. The wider the range, the more complete the listening experience
Battery life: When choosing, pay attention to the battery life of the charging case. The longer the time, the more convenient it is to use
Time delay: The smaller the value, the better; otherwise, an echo will occur
Battery current: It is related to the power of the hearing aid, the amplifier circuit, the receiver model, etc., and reflects the power consumption level of the hearing aid
Protection grade: IP68, where "6" represents the highest dust protection grade and "8" represents the highest water resistance grade
After learning these parameters, do you feel that you are terrifyingly strong? If you still don't understand any parameters when choosing a hearing aid, feel free to ask in the comment section. Flysound is always ready to answer your questions!
