Why does hearing loss start at high frequencies?

In general, sensorineural hearing loss begins at high frequencies, while conductive hearing loss generally decreases at low frequencies. Sensorineural hearing loss, such as drug-induced toxic deafness, noise-induced deafness, etc., because both drugs and noise will damage the external hair cells of the cochlea, and the external hair cells of the cochlea are sensitive to high-frequency sound and play a role in discriminating, so sensorineural hearing loss generally starts from high frequencies.

Generally, there is more decline from high frequency, because the cochlear part of the human person is the bottom of the snail at the outermost, and the bottom of the cochlea plays a role in the analysis of high frequency, and the top of the cochlea is located inside the cochlea is generally less damaged, so the general hearing loss starts from high frequency, of course, there is also a decline from low frequency, depending on the person.

Hello, hearing begins to decline from high frequencies, generally in addition to the body's own reasons, there are also external factors, such as: whether the working environment is noisy and noisy, whether you often wear headphones to listen ** and so on will affect the decline of hearing high frequencies.

In most patients, the audiogram curve is decreasing, and only a few rare cases are low frequency difference and high frequency are good, which is caused by normal auditory nerve deterioration.

Hello, sensorineural hearing loss and mixed hearing loss are both types of low-frequency and high-frequency differences.

Hello, generally from the high frequency of the drop is more, of course, from the low frequency to the beginning of the decline, from the person to the person.

High-frequency hearing loss is generally due to sudden deafness, hereditary hearing loss, hearing loss caused by noise environment, etc., hearing loss varies according to the degree and type, and high-frequency hearing loss is one of the most common hearing loss, which is shown on the audiogram in the range of 2000-8000Hz, and the Changying fibrillation nucleus of the sound is the greatest benefit, which can be amplified by 10-15db at the tympanic membrane, and the hearing loss caused by noise is often located at one octave of the noise frequency. The natural formant peak of the external auditory canal is 2kHz-4kHz, so it is most likely to cause hearing loss in the frequency range of 4kHz-6kHz. Therefore, noise-induced deafness usually starts at around 4kHz and gradually affects the surrounding frequency.

The main causes of hearing loss that generally start at high frequencies are as follows:

High-frequency hearing loss is caused by damage to the hair cells in the cochlea, the main organ of hearing that receives sound and converts it into nerve signals, so high-frequency hearing loss is usually the first to appear.

High-frequency sounds have higher frequencies and shorter wavelengths, making them more susceptible to noise and harundou damage, while low-frequency sounds have longer wavelengths and are easier to propagate and bypass obstacles, so low-frequency hearing loss is comparatively less.

High-frequency sound plays an important role in hearing, such as distinguishing between speech, **, and other sounds, so high-frequency hearing loss can have a greater impact on a person's communication and entertainment.

In conclusion, high-frequency hearing loss is one of the more common types of hearing loss, mainly due to damage to the hair cells in the cochlea. If detected and taken in time, further hearing loss can be effectively avoided.

Generally, there is more decline from high frequency, because the cochlear part of the human person is the bottom of the cochlea at the outermost, and the bottom of the cochlea plays the analysis of high frequency, and the top of the cochlea is located inside the cochlea is generally less damaged, so the general hearing loss starts from high frequency, of course, there is also a decline from low frequency, which varies from person to person.

Generally speaking, the frequency range that the human ear can hear is between 20Hz and 20000Hz, and the frequency above 4000Hz is called high frequency. For normal communication between people, only the 500Hz to 3000Hz frequency of the cochlea needs to have normal hearing function, so when high-frequency hearing is damaged, people are often completely unconscious. The frequency of hearing loss caused by tweeter headphones is precisely at high frequencies.

Once the high-frequency hearing is reduced, it will slowly expand to the low frequency, if the high-frequency leakage level hearing loss does not attract people's attention, noise pollution still exists, and the horizontal hearing problems in other frequency bands will also affect people's normal language communication.

There are several causes of hearing loss, mainly physiological and pathological.

Physiological causes: As we age, the auditory system deteriorates, leading to hearing loss. In addition, bad habits such as long-term exposure to noise and the use of headphones can also damage hearing.

Pathological causes: Hypothetical descents may be caused by otitis media, excessive earwax burial, noise-induced deafness, sudden deafness and other pathological pure rolling causes. Otitis media can cause symptoms such as ear pain, pus, and hearing loss; Too much earwax can affect hearing, leading to deafness; Noise-induced deafness is caused by long-term exposure to high-decibel noise; Sudden deafness is caused by a sudden onset of hearing loss.

If hearing loss interferes with normal life, it is advisable to seek medical attention and seek professional advice.

There are many causes of hearing loss, presbycusis refers to damage to the auditory nerve, resulting in hearing loss. There are many causes of auditory nerve damage, including high blood pressure, diabetes, and all diseases that can affect the end of the circulation can cause hearing loss; In the past, it should be noted that drug-induced deafness also damages the auditory nerve; There is also a part of the hereditary cause. But it should be reminded that the cause of hearing loss is not easy to investigate.

If hearing loss is found, the first thing to do is to do a basic hearing examination, to determine the extent of the drop, and whether the fibrillation cavity needs to be immediately **. Sudden deafness in general, which needs to be done immediately**. Now there is an unexplained disease of unknown origin, which requires ** to be very timely, like stroke, to be able to take medication for six hours, the probability of recovery is basically 100%, and then it will be carried out after a week**, the chance of recovery is basically only about 50%, so it is imperative to detect hearing loss as soon as possible and treat it.
