Why do you need hearing aids for both ears

The human auditory language system is a complex system, which needs the joint participation of the outer ear, middle ear, inner ear, auditory nerve, auditory center and speech center. The damage of any link can cause the hearing damage, and then affect the speech function, thus affecting the social communication and quality of life. Hearing aids can compensate for hearing loss to some extent. Generally speaking, hearing aids should be worn as early as possible when hearing loss of both ears reaches a certain degree. But in real life, many parents will only choose one or no hearing aid for hearing impaired children, considering the factors of economy, beauty and so on

It is the most common manifestation of asymmetric hearing loss to “listen” with only one ear. This kind of hearing loss can be unilateral hearing loss or bilateral hearing loss. Long term non-interference of asymmetric hearing loss will lead to a series of serious disorders. In addition to hearing loss, these manifestations also include obvious language retardation, mental retardation, communication disorders and so on. ,

In clinic, asymmetric hearing loss is defined as hearing threshold difference of 15dB HL or speech recognition rate difference of more than 20%.

However, the performance of asymmetric hearing loss is often not obvious. When children suffer from asymmetric hearing loss in childhood, parents often dismiss it for the following reasons:

1. The early hearing loss of the children is not obvious, until they gradually appear learning disorder, social and emotional disorders, they gradually show hearing loss, which can not be detected by the parents;

2. After hearing screening, it is found that the child has hearing loss disorder, but the parents think that the child can still hear the sound with the help of the healthy ear, so there is no need to take intervention measures;

Research shows that asymmetric hearing loss can affect the development of brain auditory pathway, and then make poor ears show more obvious damage. If parents do not intervene, children will show more obvious hearing loss and other mental development disorders in the development process:

Listening

1. Relying on one ear for a long time will gradually aggravate the hearing loss of poor ears, lead to hearing deprivation, and affect the development of auditory pathway

2. < a href = "http://www.sqhearing.com/tlkp/32.html" target = "blank" > one ear listening can’t locate the sound source

3. There is obvious hearing loss disorder in noisy environment, and many people cannot hear the target speech clearly when talking
