Five manifestations of hearing loss in high frequency area

< P style = "color:; font family: Arial, Verdana, sans serif;" >
In life, normal listening is to be able to hear all the phonemes in the low-frequency and high-frequency areas, and to hear a large range of clear, layered sound, just like a colorful landscape painting. But with high-frequency hearing loss, not only the sound is hard to hear, but also the sound is hard to distinguish clearly, like a faded picture. If there are the following manifestations in daily life, it can be regarded as high frequency hearing loss.

Performance 3, pronunciation, enunciation is not clear, there is “big tongue” phenomenon, do not love to talk, do not love to communicate with everyone;

What should we do after hearing loss is found?

1. Hearing aid

< P style = "color:; font family: Arial, Verdana, sans serif;" >
Use hearing aids to amplify sounds to help patients with conductive or sensorineural hearing loss, especially those with normal speech frequency hearing loss. Hearing aids can also help patients with high frequency hearing loss or those with single ear hearing loss. The hearing aid uses a microphone to collect the sound, an amplifier to increase the volume, and a loudspeaker to conduct the amplified sound.

Air guided hearing aids are usually superior to bone guided hearing aids and are most commonly used. There are body type, ear back type, contralateral signal type and bilateral cross signal type.

The body type hearing aid is often used for the severely hearing loss, which has the strongest power. It can be put in the pocket of clothes and connected to the earplug through the wire. Because it is easy to operate, not easy to damage, and overcomes the problem of ear mold discomfort, so infants or children often use it.

For moderate to severe hearing loss, ear back hearing aids can be used; for light to moderate hearing loss, ear back hearing aids with low power can be used, with relatively small volume. The inner ear hearing aid is smaller and completely placed in the ear canal. It is suitable for patients who are unwilling to take the hearing aid outside. The contralateral signal hearing aid is suitable for patients with single ear hearing loss. The microphone is placed in the non responsible ear and transmitted to the responsible ear by radio or transmission conductor. This hearing aid enables the patient to hear the voice of the non responsible ear and helps to determine the sound source. If the responsible ear also has some degree of hearing loss, bilateral cross signal hearing aids can be used.

Bone conduction hearing aid is suitable for those who can not be equipped with air conduction hearing aid. If there is no external auditory canal or secretion in the middle ear, the hearing aid is in contact with the head, usually placed behind the ear and fixed with rubber band. The sound passes through the skull to the inner ear. The power of bone conduction hearing aid is high, which causes discomfort. Some bone guided hearing aids can be implanted in the bone behind the ear.

2. Cochlear implantation

< P style = "color:; font family: Arial, Verdana, sans serif;" >
Cochlear implantation can be used in patients with severe hearing loss who can’t hear through hearing aids. The implant consists of an electrode inserted into the cochlea and an internal driver placed in the skull, which is connected with an external driver, a language processor and a microphone. The microphone collects the sound wave, and the processor converts the sound wave into an electric impulse, which is transmitted to the internal driver through the external driver, and then to the electrode. The electrode current stimulates the auditory nerve.

Cochlear implant is not like the normal cochlear to change the voice, which has different effects on different patients. It can help some patients to lip read, some patients can distinguish some words, some patients can listen to the phone. Cochlear implants can also help the deaf to listen to and distinguish between environmental sounds and alarm signals, such as door ringing, telephone and alarm clock sounds. Cochlear implant is more effective for hearing loss or successful use of hearing aids.
