Compared with wearing hearing aids on one side, bilateral hearing aids have obvious advantages.After recognizing the necessity and importance of bilateral hearing aid, as long as possible, it must be worn on both sidesHearing aid.This is especially important for the elderly.Because patients with presbycusis have poor auditory resolution and severe rejuvenation, they need to be clearer and can effectively limit excessive sound outputHearing aid.
The advantage of wearing a hearing aid for both ears is to help the elderly hear better.why?
1. Only by listening with both ears at the same time can there be a sense of auditory direction and the ability of auditory orientation and positioning.
2. Of course, the same sound is louder to hear with both ears, so it can reduce the output of the hearing aid, which is equivalent to obtaining 6 decibels of “real hearing” invisibly.
3. Because it can produce a “stereo effect”, wearing a hearing aid in both ears can improve the user’s voice resolution ability.For example, in a noisy environment, binaural hearing can suppress and reduce the intensity of noise, and improve the user’s understanding of speech sounds.In a reverberant sound environment, the effect of wearing hearing aids on both ears is more prominent.
4. Binaural hearing aids can allow users to hear weaker sounds.
5. As it conforms to human hearing habits, wearing hearing aids in both ears will make users feel more natural and comfortable.
6. Binaural complementation can effectively reduce distortion, make the signal sound more real and clear, and it is easier to produce a sense of spatial balance.
7. Listening to both ears at the same time makes the sound sound coherent and rich, thereby improving the quality of the heard sound.
8. Both ears are “used” directly, which can effectively avoid the useless hearing function decline of unaided ears due to weak signal stimulation.
Because of this, many presbycusis can no longer tolerate the defects of single ear hearing aid once they have used binaural hearing aids.
