How long does a hearing aid take?
It usually takes 2-4 weeks: the first week wears 1-2 hours per day in a quiet environment, then gradually prolongs and transitions to a noisy environment.

不适用情形：Patients with sudden deafness, loss of conductive hearing or ear inflammation should first consult the ear, nose and throat department, in accordance with medical instructions; this does not apply to children under 6 years of age.
警示：Hearing aids are subject to a professional hearing test to select the power slot; if there is an increase in the ringing and dizziness of the ears after wearing them, stop using them and consult a doctor.
产品详情
Digital hearing aids hand over microphones to digital chips for split processing, compensate for gains and suppress environmental noise by the user ' s hearing curve, making the speech clearer and less loud.
Matching process
- (a) Pure sound monitoring: confirmation of the extent of loss of hearing in the frequency bands (recommended to be completed at a professional institution or a matching centre);
- Selecting: Selecting the inner ear or customized ear style to determine the power slot according to the degree of loss;
- Computer matching: write to the hearing curve and set maximum output and noise reduction policies;
- Retrospective fine-tuning: 2 weeks later, adjusted to the actual hearing.
Adaptation period recommendations
1st week wears 1-2 hours per day in a quiet environment; 2nd week extends up to 3-4 hours and tries to watch television; 3th week gradually enters a noisy environment such as kitchens, public transport, etc. Gradually, most people can adapt in 2-4 weeks.
Maintenance point
Batteries are removed every night, sound holes and microphone holes are cleared with a special brush; dynamic protection against falling and dry boxes are recommended during the rainy season.
常见问题
Why did you put it on so loud?
It is strange and normal to re-enrich the sound of the environment after a prolonged lack of acoustic stimulation; it can be mitigated by the opening of the scene mode of noise reduction.
Can you adjust your volume?
Yes. The body key supports multi-tempo volume and program switching; a more sophisticated multi-channel debugging can be done by matching software.
