The advantages of wearing a hearing aid in both ears are:
● Improve the ability to identify sound orientation.
● Make you sound relaxed and effectively improve your language understanding.
● Effectively suppress noise in a noisy environment, making it easier to understand other people's conversations and listen freely.
● Greatly reduce the risk of further "deafness"
● Make it easy for you to get a more perfect, comfortable and pleasant sound.
● Identify the sound source and improve the sound source positioning ability.
Why do people have two ears? Because the brain needs two ears to input information to judge the direction of sound.
For example, when the car horn rings, the sound signal reaches your brain. In a very short time, the brain will compare the information received by two ears according to the energy, the intensity of sound waves and the time to reach the ears, and immediately judge the direction of the car and its distance from people. This process is called "sound source localization".
We can judge the position of sound according to the physiological distance between our ears. For example, the car horn on your left side takes less time to reach your left ear and has more energy than your right ear. That's why you can immediately know that the car is approaching quickly from the left. This natural method can make you live a safe and comfortable life every day.
Typical noisy situation
Imagine a daily situation, such as talking at the dinner table. You want to talk to the person next to you, but other people in the family are also talking. At this moment
This background noise not only makes you unable to hear clearly, but also makes you unable to understand what others are saying. You try to make up for it by turning up the volume of the hearing aid, but it will only get worse. All the sounds are amplified, not the sounds become
More clearly, you will turn down your voice again, and then the sound you hear will get worse.
Fight against noise
Binaural noise suppression: If the hearing of both ears is decreased and only hearing AIDS are worn, you will obviously feel inaudible in a noisy environment, just like a normal hearing person blocking his ears with one hand in the same environment. You can let your family do such a small experiment in a noisy place to experience your sense of hearing. )
Wearing hearing AIDS in both ears can give full play to the binaural hearing function in the nervous system of brain auditory pathway, which is helpful to noisy environment.
Improve speech resolution, effectively suppress background noise, and make you hear more clearly. In addition, wearing a hearing aid in both ears can reduce the output power of the hearing aid by about 5dB, which can protect yours.
Residual hearing, more importantly, because the sound that needs to be amplified by hearing AIDS is relatively reduced, background noise will no longer bother you and annoying howling will be far away from you!
Improve the loudness of sound: Compared with single ear wearing, binaural wearing improves your actual listening effect by about 6dB. In other words, it can make you listen easily, improve your language understanding ability and reduce the possibility of sound feedback.
Eliminate the head shadow effect: If you wear a hearing aid in one ear, the skull will block and attenuate the sound transmission, which is the head shadow effect. head
Shadowing effect means that the hearing-impaired ears without hearing AIDS can't hear or locate the sound source under normal circumstances, especially for high-frequency sounds greater than 1500Hz, the attenuation can be as high as 10- 16 dB, which is very difficult for language.
Clarity and understanding of speech are very important. Moreover, binaural hearing AIDS can fundamentally solve the head shadow effect and prevent attenuation caused by the head shadow effect. You don't have to worry about the embarrassment of turning your head to listen to the sound, no
You need to turn your head back and forth again so that you can listen easily.
Reduce the risk of hearing loss
Binaural hearing AIDS can reduce the risk of further hearing loss. Meet the requirements of binaural matching, but only choose one hearing aid, from hearing to hearing.
From a mechanical point of view, it is called "putting an ear", which means wasting the hearing of one ear. If this ear with residual hearing is not used for a long time and lacks sound stimulation, it will lead to the loss of auditory nerve function of the brain.
And lose the ability of sound processing, so that the hearing function is completely damaged. Therefore, the earlier you wear hearing AIDS in both ears, the less likely this danger will occur.
If the hearing-impaired ear is placed for a long time, even if the hearing aid is selected again, it will be difficult to restore hearing because of the loss of brain processing ability.
Hearing loss in children
Reducing the risk of hearing loss is particularly important for children with hearing loss. For a growing child, the brain and auditory nerve
The ability to process sound information is gradually developed with the growth of children. The younger a child is, the easier it is to recover his voice, which is more conducive to the development of children's various abilities, and it is also easy to establish the connection between brain and voice. this
The ability to listen to and imitate sounds will lay the foundation for the future development of children's language ability.
However, if the child's sick ear is not stimulated by sound for a long time, it will lead the child to miss the best period of speech rehabilitation (3-6 years old), leading to aphasia. However, missing this crucial speech learning period will have a great negative impact on children's future speech communication, life, study, work and lifelong happiness. Therefore, it is necessary to put hearing AIDS on children's ears as soon as possible.
A more perfect and beautiful voice
Imagine that you are listening to a program on the stereo. It has two amplifiers and two speakers, which makes the music sound more real and upright.
However, if there is only one amplifier and one speaker is working, the sound will sound monotonous and the sound quality will be much worse. Similarly, if your ears have the same hearing, you will sound much more comfortable. you
You can hear clear and natural sounds without effort, and fully appreciate the breadth and sense of space of the sound.
If you should wear two hearing AIDS, but only one, you will feel the above. Fortunately, your audiologist can improve all this by matching the right hearing AIDS for your ears.
Disadvantages of wearing hearing AIDS in both ears
The cost of choosing a binaural hearing aid is higher than that of choosing a monaural hearing aid, but although you spend more money, what you get is good hearing and high quality of life that money can't measure.
The debugging time of binaural hearing AIDS is longer than that of monaural hearing AIDS.
Be nice to yourself.
If you are indeed deaf in both ears, you should consult your hearing consultant and follow the advice of others. Ask your hearing consultant to choose two hearing AIDS for you and give yourself the necessary time to get used to them.
Be kind to yourself and wear two hearing AIDS, you can not only feel the benefits of having more complete hearing, but also feel the improvement of the whole quality of life.
