How to use hearing aids for people with hearing loss in both ears
In the case of economic conditions, be sure to wear both ears:
1.Strengthening noise reduction and speech understanding The ear of the human ear has a sound collection and noise reduction function. For a hearing-impaired hearing loss patient, it is important to strengthen the signal-to-noise ratio. Wearing the ears means that the two auricles have both sound collection and noise reduction capabilities, which is of great significance for enhancing the language resolution.
2.Increase listening comfort and participate in multi-person conversations. Because the binaural optional hearing aids improve the ear’s own sound collection, noise reduction, gain, positioning, balance function and fusion effect, the hearing loss patients will greatly hear the sound signals heard. Increased signal to noise ratio and excellent listening comfort. Therefore, hearing loss, wearing a hearing aid with both ears, can easily face the need for multi-party conversation. It will greatly help people with hearing loss to live, study, work, socialize, meet, etc.
3.Improve the sound source positioning ability The human ear has a strong sound source positioning ability. However, its prerequisite is that both ears must have the same hearing threshold. During the transmission of air, there will be changes in energy and speed. If the hearing loss and the threshold are asymmetrical, most of the sound from any direction will be heard by the better hearing threshold, so that the sound source cannot be determined. The direction. Therefore, the hearing loss patient’s binaural hearing aid can better improve the positioning ability of the sound source.
4.Avoid late-onset hearing deprivation. In patients with bilateral hearing impairment, if you only choose to wear a hearing aid, the ability of the auditory center without the hearing aid ear to gradually understand the language will gradually decline. Progressive(Late)Sexual deprivation effect, the longer the time, the more serious. The main reason for the auditory deprivation effect is that the ear of the hearing aid conveys enough information to the brain that the brain no longer pays attention to the ear without the hearing aid, and the brain seems to give up the attention to transmitting the weaker signal ear. In order to avoid this phenomenon, the most effective solution at present is to simultaneously select hearing aids for both ears.
5.Delaying the decline of auditory nerve function Resolving auditory deprivation is to solve the progressive decline of central nervous function. Life is in motion, and the nerve cells in the central nervous system can achieve the purpose of exercise by the stimulation of sound. Therefore, it is very important for each patient with bilateral hearing loss to be able to have both ears in a normal vocal state, and to stimulate the excitation of the auditory nerve by acoustic stimulation.
6.Enhanced binaural loudness integration effect The binaural hearing is higher than the single ear. At the threshold level, the binaural threshold is better than the monaural threshold.3decibel. At the threshold level, the binaural threshold is better than the monaural threshold10decibel. Therefore, wearing the hearing aid with 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 the hearing aid entering saturation is reduced, which is more helpful to improve the speech intelligibility after hearing aid.
