Should I wear one or two hearing aids

Should one or two hearing aids be worn? Experts stressed that as long as conditions permit, two hearing aids must be worn. Wearing hearing aids on both ears is in accordance with the law of auditory science. Both sides of the brain can receive sound information from both ears at the same time, producing a “stereo” effect. It helps to locate the sound, eliminate the interference of environment sound, and improve and restore the selective listening ability. And the decibel sound output is increased invisibly, and more importantly:

1. Only when hearing aids are worn on both ears can you have a sense of direction. Scientific research shows that the effect of human auricle on listening to sounds from different directions is different. In front of each ear, the range of zero to 120 degrees is the best place to listen. Because of this feature, people can determine the exact direction of the sound source by rotating the head and ears to feel different volume of the same sound and the time when the sound is transmitted to the brain, but only one ear is different.

2. Selective hearing ability can be achieved only when hearing aids are worn on both ears. When listening to the sound signal with both ears, people can determine the exact direction of the sound source through the difference of the volume and the arrival time of the sound signal felt by each side of the ear for the same sound, so they can concentrate on listening to a certain sound. In the case of only one side of the ear, because the direction of the sound can not be identified, only different tones can be used to listen. However, due to the fact that high sound pressure can suppress low sound pressure in different sound signals, one ear cannot hear clearly. We can do an experiment: when there are many people talking, we make a recording at the same time, and then ask the party to listen to the recording again. As a result, we will find that the party can’t hear the recording clearly because of the suppression effect of high pressure on low pressure at the same time.

3. Hearing aids on both ears can increase language recognition ability. In practice, we can find that most people can increase their speech recognition ability when they listen to binaural listening. For a few people with poor speech recognition ability, it is very valuable to increase recognition ability by 5%.

4. Wearing hearing aids on both ears can reduce the power of hearing aids and better protect hearing. When wearing hearing aids, the output power of both ears can be reduced by 5dB respectively, which is beneficial to the hearing impaired people, one is to protect their residual hearing; the other is to reduce the noise due to reducing the output power, which is beneficial to the people wearing hearing aids.

5. Wearing hearing aids on both ears can better restore the physiological function of the human ear. This mainly refers to the hearing function and speech recognition ability of both ears, and the recovery of normal state.

6. Wearing hearing aids on both ears can avoid unilateral hearing loss. Wearing hearing aids on both ears can avoid the disuse of the opposite ear function caused by the use of hearing aids on one side.

7. Users can have more reliable insurance coefficient. For example, when the hearing aid of one ear fails, there can be another side to ensure the work.

8. Wear hearing aids on both ears, which can provide more flexibility in use. For example, if one side is uncomfortable to wear, it can be replaced; if one side has recurrent ear disease, it can have the other side’s protection, etc.

9. Most people with hearing impairment want to wear two. This is true even for users who are not satisfied with the existing hearing aids. Because of wearing ears

10. The experience of developed countries and regions proves that hearing aids should be used in both ears. For example, in the United States, Canada and other European countries, and even in Taiwan, more than 90% of hearing aid users use two ears.
