First, it is necessary to clarify what the purpose of wearing a hearing aid is:

1. Compensate for hearing loss: On the basis of the patient's residual hearing, make up for the missing sounds. 2. Restore functional hearing: Understand others' speech and locate sound sources in complex environments. 3. Reduce auditory fatigue: Avoid the listening burden caused by excessive sound amplification or signal distortion. Before purchasing, compare the hearing test results with the hearing aid parameters to ensure that the physical performance of the hearing aid meets the patient's hearing needs, such as full-range gain, frequency response range, etc.

Let's first look at "Daily Communication" : the most fundamental test

The core function of a hearing aid is to help us hear conversations clearly, so its performance in daily communication is the first "touchstone". If you put it on, 1) when chatting with your family at home, they don't have to deliberately raise their voice, slow down their speaking speed or frequently repeat their sentences. 2) There's no need to turn up the volume very high when watching TV. 3) Be able to hear the voice on the other end of the phone clearly when making a call. That indicates that the basic effect has met the standard.

The wearer can also have their family members test their monosyllabic word recognition rate in a quiet environment at home. The testing process includes: ● Downloading an APP on a smart phone or going to a hearing testing institution to play a standardized vocabulary list; ● The subjects receive sound signals; ● Ask the subjects to repeat the monosyllabic words they have heard; Calculate the percentage of the number of correctly recognized words to the total number of test words. Test once before and once after wearing to see if the recognition rate of monosyllabic words has improved.

Experience "Comfort" : The key code for long-term wearing

A good hearing aid is not only about "hearing clearly", but also about "hearing comfortably". First of all, it is necessary to check whether the material used in the hearing aid is skin-friendly and choose the appropriate ear cap before wearing it. Then, observe whether the ears will swell after wearing it for a long time, whether it feels like the ear canal is "blocked", swollen and uncomfortable, and even wants to take it off after wearing it for a while. If the hearing aid is still like this after being adjusted by a hearing aid fitter, you should consider whether it is really suitable for you. If there is no obvious discomfort in the ear canal after wearing it for a long time and the surrounding sounds very natural, it indicates that the comfort level is up to standard and it is suitable for long-term wearing. You can record the duration of wearing it every day and gradually increase the wearing time step by step.

Try "specific scenarios" : the ability to deal with complex environments

Daily life is not only about the quiet home, but also involves going to noisy places such as supermarkets, restaurants and farmers' markets. These places can better test the performance of hearing AIDS. After the hearing aid is properly adjusted, try going to the supermarket to buy groceries or to a restaurant with your family and friends. A good hearing aid has noise reduction function. If one can chat with colleagues in such a noisy environment, hear the service staff clearly and locate the general direction of the sound, it indicates that the noise reduction function and the directional microphone effect of the hearing aid are quite good.

Finally: Give each other a little "adaptation period"

It should be noted that after hearing loss, the brain has become accustomed to the state of "not being able to hear clearly". When a sudden sound comes in, an adaptation process is needed. At the beginning, you may feel that "there are too many and too chaotic sounds", or "you can hear clearly but can't react in time". This is not because the effect is bad, but because the brain is "relearning" to process sounds. First, adapt to a quiet environment, and then gradually transition to complex scenes. As time goes by, you will increasingly feel the changes.
