What are the routine tests for general hearing loss?

Acoustic impedance: check the middle ear 2, inner ear CT: check the inner ear 3, pure tone audition:

125-8000 Hz hearing test. 4. MRSRR multi-frequency steady-state: comprehensive audiometry for children who do not respond to low, medium and high frequencies.

5. Brainstem evoked potentials (ABR). ABR brainstem evoked potentials: 2000-4000 Hz hearing test (for non-responders).

General hearing testing can be divided into subjective testing and objective testing, and the main observational hearing includes: pure tone hearing detection, speech audiometry and behavioral audiometry; For people who are unable to subjectively cooperate with audiometry, only objective hearing detection methods can be used, and common objective tests include: brainstem evoked potentials, otoacoustic emissions, 40Hz hearing-related potentials, etc.

If you are constantly in a state of rapid noise and irritation, it will cause the autonomic nerves in the body to lose their normal regulatory function, causing ischemia, edema and hearing impairment in the inner ear organs, which is prone to sharp hearing loss. So, try to keep yourself in a relaxed and happy mood.

Common hearing tests are divided into two categories: primary observational hearing (e.g., tuning fork examination, pure-tone audiometer examination, speech audiometry) and objective audiometry (acoustic impedance, otoacoustic emission, auditory evoked potential).

If any changes in hearing are noticed, a hearing test and symptomatic examination should be done as soon as possible**. Because there are some sudden hearing loss, it is possible to recover or improve with timely examination and intervention. Let's focus on hearing health, early detection, early intervention, and minimise the impact of hearing loss.

Keep your hearing for a lifetime.

01Is there a high-risk group of hearing loss?

After the age of 50, the body organs begin to "age" to varying degrees, as do the hearing organs in the ears, and even the auditory center in the brain begins to degenerate. There is a small sound that cannot be heard, or the sound cannot be heard clearly.

If you are over 50 years old, it is recommended that you have a hearing test every year to achieve early detection, early intervention, and early **.

Working people in high-intensity noise environments.

The auditory hair cells of the inner ear are very sensitive to sound, and when the sound is too loud, it can cause the auditory hair cells to be damaged or die. Damage to auditory hair cells that cannot be healed on their own or recovered by medication causes hearing loss, which is called "noise-induced" hearing loss.

If you wear headphones for a long time and the sound is turned on very loudly, or you often work under high-intensity noise (such as: electric drill sound, karaoke, etc.), the sound intensity reaches 85db or greater, and the hearing is easily damaged, it is recommended that such people have regular hearing examinations.

02Do you have hearing loss?

If you have any of the above 2 or 3 problems, it may be an early sign of hearing loss, and it is recommended to go to a hospital or a professional fitting center for a hearing examination.

03Regular hearing checkups.

For hearing aid wearers, it is recommended to have their hearing checked at least once a year. If there is a change in hearing and the hearing aid cannot meet the daily listening needs, you should go to the fitting center to check or adjust the hearing aid in time.

In the following situations, a hearing test should be done: 1. People speak loudly, and they can hear the sound but can't hear the content clearly; 2. It is difficult for others to listen when they are talking behind their backs or in other rooms; 3. You need to look at other people's lips face-to-face to understand what the other person is saying; 4. In noisy environments such as public places, it is difficult to listen; 5. Turn up the volume of the TV or radio; 6. I can't hear what the other party is saying clearly; 7. Have to repeat it several times to hear what is being said; 8. Some patients are accompanied by tinnitus, which is often high-frequency sound, which is intermittent at the beginning, appears in the dead of night, and gradually becomes persistent later.

If one of the spouses is deaf or has a family member with congenital deafness, deafness genetic screening can be done to find out whether they carry the deafness gene and whether it affects the next generation.

Clause. 2. Couples who have already given birth to a child with deafness and plan to give birth again can be tested for deafness genetic testing of both husband and wife to assess the risk of deafness in the second child, so as to achieve eugenics.

Clause. 3. People with unexplained deafness need to be screened for deafness genes, including patients with congenital deafness and patients with acquired deafness.

Clause. 4. People with normal hearing who have unexplained or clearly hereditary hearing loss in their families, and people who want to test whether they are carriers of deafness genes.

The most basic test of hearing is "pure tone audiometry", which can test the entire auditory conduction pathway from the time the sound waves are collected by the pinna to the time the sound waves are converted into nerve impulses and transmitted to the auditory center of the brain.

If there is a problem here, the test for the middle ear - "acoustic conduction resistance" comes in handy, which can reflect whether the anatomy of the middle ear is damaged, whether the tympanic pressure is abnormal, whether there is fluid exudation, and then judge the occurrence and development of middle ear lesions.

Passing through the middle ear, the sound waves are transmitted to the inner ear, the hearing organ of the inner ear is mainly the cochlea, at this time for the cochlea's hearing test item - "otoacoustic emission" came into being, the reason why it is called "emission", is because this test can collect the audio energy actively emitted by the cochlea, if the collected audio energy is enough, it can prove that the cochlea is working properly.

When there is discomfort in the ear or a feeling of hearing loss, a doctor or audiologist usually needs a hearing test to determine whether the person has a hearing problem. Older people Young people.

Some special factories, such as noisy companies, will have hearing tests when recruiting employees.

1.People speak, can hear but can't hear the content 2Others are talking behind their backs or in other rooms, and it is difficult to listen 3You need to look at someone's lips face-to-face to understand what the other person is saying.

2. OAE otoacoustic emission 3, acoustic impedance: check the middle ear 4, inner ear CT: check the inner ear 5, pure tone audition: 125-8000 Hz hearing examination. 6. MRSRR Multi-Frequency Steady-State Guidance:

People who don't have very good ear hearing in their daily life.

Anyone who feels that they have a hearing problem should go to the hospital for a check-up.

Any changes in hearing should be done as soon as possible to have a hearing test and symptomatic examination**. Because of some sudden hearing.

Subjective examination: There are many applications, including, 2

Ear grammar: the initial test of hearing, generally let the patient stand far away, such as 3-5m, do not let the patient see the doctor speak, need to whisper, observe whether the patient can hear, the first test generally stands farther to hear, the better the hearing.

Tuning fork test: When the doctor is in the office, the patient's hearing is initially tested, and the tuning fork examination is judged to be monodeaf, binaural deafness, conductive deafness, inductive deafness, mixed deafness, and the tuning fork is more accurate than whisper audiometry, and there are many types.

Pure-tone audiometry: This is done in the hospital's hearing room and can be both quantitative and qualitative.

There are two types of hearing tests:

1. Subjective hearing test, pure tone audiometry, mainly suitable for older children and adults, can cooperate with the operation, but because the patient's cooperation is required, there are some errors in some cases.

2. Objective hearing examination, including brainstem evoked potentials, which is mainly suitable for small children, trauma patients, and patients who cannot cooperate with the examination, at this time brainstem evoked potentials need to be used. The measured values of brainstem evoked potentials are more accurate, but they take a long time and cost more, so they are suitable for patients who cannot cooperate.

A tuning fork can be used, usually placed about 1 cm away from the opening of the patient's ear canal, and the audible word is "air conduction"; The words that can be heard on the skull are called "bone conduction". If the number of examples heard by voice detection is shortened to about 4 m, it means that the patient has mild deafness, if it is 1 m, it is moderately deaf, and if it is less than 1 m, it means that the patient has severe deafness.

Hearing clearly, occasional interruptions, unclear development, etc., it is recommended to go to a professional hearing center to check the hearing, preferably, it is recommended to check the hearing twice a year, pay attention to the changes in hearing in time, and if there is a problem, timely ** and intervention.

Suspect that you are hard of hearing. It is best to go to a regular hospital. Ear. Go check your own, hearing. The doctor will give you a satisfactory answer.

If you suspect that you are not hearing well, you need to have a hearing test.

Go to a regular hospital for a check-up and do a hearing test to understand!

If you have bad hearing, you can go for a hearing test, according to this test** or get a hearing aid.

Hearing changes are manifestations of ear disorders or other systemic diseases in the ear. Hearing loss is often accompanied by other symptoms, so it is important not to neglect the examination of other signs when examining hearing. From the perspective of audiological examination alone, it can be divided into two categories, namely subjective hearing examination and objective hearing examination.

Subjective hearing test refers to the cooperation of the person being examined during the hearing test, such as pure tone hearing threshold audiometry, speech audiometry, etc. Objective hearing test refers to the evaluation of hearing through the recording of various indicators by instruments without the cooperation of the person being examined.

The general examination procedure is as follows: first, the external auditory canal and tympanic membrane are examined, and pure-tone audiometry is routinely performed to evaluate the hearing threshold. Acoustic impedance audiometry is performed to evaluate tympanic function.

If necessary, brainstem electrical response audiometry is performed to evaluate the conduction function of the cochlea, auditory nerve, and center. Verbal audiometry is performed to evaluate the ability to distinguish sounds. There are a number of other audiometry methods used to determine the location and nature of hearing loss.

In conclusion, hearing testing is a complex process that requires a combination of methods to arrive at an accurate diagnosis. (Liu Zhiming).
