Summarize the six benefits of wearing hearing aids in both ears

Due to the cognitive misunderstanding of hearing loss patients or their families, many patients only plan to wear one Hearing aid .In fact, seeing the world with both eyes is as important as listening to the world with both ears. Therefore, it is very important to wear hearing aids in both ears.Hearing Aids Made in ChinaThe editor has compiled the following six benefits.

 

1. Strengthen the ability of noise reduction and speech comprehension

The auricle of the human ear has functions of sound collection and noise reduction.For a hearing impaired hearing loss patient, it is very important to strengthen the signal-to-noise ratio.Binaural wearing means that the two auricles have the ability to collect sound and reduce noise at the same time, which is of great significance to strengthen the ability of language discrimination.

 

2. Increase listening comfort and participate in multi-person conversations

Because the ears are equipped with Chinese-made hearing aids to improve the ear’s own sound collection, noise reduction, gain, positioning, balance functions and fusion effects, the hearing loss patients will greatly increase the signal-to-noise ratio and the polarity of the sound signals they hear. Good listening comfort.therefore,Hearing loss, Worn on both ears Hearing aid , You can calmly face the needs of multi-party conversations.It will bring great help to the life, study, work, social interaction, meeting, etc. of patients with hearing loss.

 

3. Improve sound source localization capabilities

The human ear has a strong ability to locate sound sources.However, its prerequisite is that both ears must have the same hearing threshold.During the transmission of sound in the air, there will be changes in energy and speed. If the hearing loss and the threshold is asymmetric, most of the sound from which direction will be heard by the side with the better hearing threshold, so that the source of the sound cannot be determined. Direction.Therefore, matching hearing aids in both ears of patients with hearing loss can better improve the ability to locate the sound source.

 

4. Avoid the effects of delayed hearing deprivation

If a patient with bilateral hearing impairment chooses to wear only one Chinese-made hearing aid, the ability of the auditory center of the ear without a hearing aid to understand language will gradually decline. Audiology calls this phenomenon gradual ( The effect of delayed onset hearing deprivation, the longer the time, the more serious it is.The main reason for the auditory deprivation effect is that the ears with hearing aids send enough information to the brain, so that the brain no longer pays attention to the ears without hearing aids, and the brain seems to give up on the ears that transmit weaker signals.In order to avoid this phenomenon, the most effective solution is to choose hearing aids for both ears at the same time.

 

5. Delay the decline of auditory nerve function

To solve the phenomenon of auditory deprivation is to solve the gradual decline of auditory central nervous function.Life lies in movement, and the nerve cells in the hearing center rely on sound stimulation to achieve the purpose of movement.Therefore, it is very important for every patient with bilateral hearing loss to have both ears in a normal sound state, and it is very important to stimulate the auditory nerve through sound stimulation.

 

6. Enhance binaural loudness integration effect

The loudness of the sound accepted by binaural hearing is higher than that of single ear. At the threshold level, the binaural threshold is better than the single ear threshold by about 3 decibels.At the upper threshold level, the binaural threshold is better than the monaural threshold by about 10 decibels.Therefore, wearing hearing aids in both ears can slightly reduce the overall gain of each hearing aid, thereby reducing the possibility of acoustic feedback and increasing the battery life.At the same time, for patients with severe hearing loss, the probability of hearing aids entering a saturated state is reduced, which is more helpful to improve speech intelligibility after hearing aids.

 

Therefore, as long as there is hearing impairment in both ears, and on the premise that there are no other contraindications to matching, we must try our best to choose binaural fitting.Let our patients realize that: 1. It is better to wear a hearing aid made in China than without a hearing aid; 2. It is better to wear it early than to wear it at night; 3. The overall effect of wearing both ears must be better than wearing one ear.
