How do I self test for hearing loss? How can hearing loss be determined?

It is necessary to do hearing tests such as ABR, ASSR, OAE, and acoustic impedance first, and judge the type and degree of hearing loss in children according to these results, and select hearing aids suitable for children according to the estimated threshold. After the fitting, it is necessary to do a sound field test and a real ear test to determine whether the hearing aid is effective for children, and whether the effect is good. At the same time, it is also necessary to have regular reviews and follow-ups, and do a good job of children's work.

In daily life, most people ignore their hearing health and often do not realize that they have hearing loss. Here's how to teach you a simple listening self-test in your daily life:

Clause. 1. It is customary to turn the head to the side of the speaker and lean forward at the same time in order to be able to hear others clearly;

Clause. 2. Will there be frequent interruptions when communicating with others;

Clause. 3. Due to hearing loss, you will often answer questions when communicating with others;

Clause. Fourth, the bird's call is inaudible;

Clause. Fifth, the TV volume will often be turned on too much, but it will always make others upset;

Clause. 6. Difficulty in communicating in a noisy environment;

Clause. Seventh, the fight is not smooth, and the family is unwilling to do homework;

Clause. 8. Will the voice increase unconsciously when speaking?

Clause. 1. It is customary to turn the head to the side of the speaker and lean forward at the same time in order to be able to hear others clearly;

Clause. 2. Will there be frequent interruptions when communicating with others;

Clause. 3. Due to hearing loss, you will often answer questions when communicating with others;

You can use the index finger and thumb to rub around the ear, if the hearing is not impaired, you can hear the rubbing sound of the thumb and index finger, if you can't hear it, it should be preliminary hearing loss, you should go to the hospital for a hearing examination.

Degree of hearing loss at DBHL.

According to international standards, the small red circle represents the air conduction result of the right ear, and the red greater than sign represents the bone conduction result of the right ear; The small blue ten prongs represent the left ear air conduction results, and the blue less than sign represents the left ear bone conduction results.

According to the definition of the International Health Organization (WHO-1997), the average hearing loss is equal to the average of 500, 1000, 2000, 4000 Hz. In Figure 1, the average hearing loss is 75 dB in the right ear and in the left ear.

Classification of degrees:

Pure tone average hearing threshold PTA: 500Hz, 1000Hz, 2000Hz The three frequency points account for 70% of the importance of determining language intelligibility, which is the key range to measure auditory function. For this reason, the World Health Organization (WHO) uses the average of hearing loss at the three frequency points of 500Hz, 1000Hz, and 2000Hz as the basis for classifying hearing loss.

In addition to the above-mentioned commonly used classification methods for the degree of hearing loss, the World Health Organization (WHO) promulgated a new classification standard in 1997, which added a hearing threshold of 4000Hz compared with the previous standard, which fully considered the high-frequency hearing loss of people with hearing impairment and has certain clinical value. The new standard is now mostly adopted.

The easiest way is to rub your hands to see if you can hear the rubbing sound, it is best to go to the hearing center to have it checked, and the hearing aid fitting center is currently free of charge.

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).

Going to a professional hearing institution is basically free, and you can better and more accurately detect hearing loss.

You can go to hospitals and fitting centers to have your hearing tested.

Go to a hospital or hearing aid fitting center for a hearing test (usually free of charge). Hearing loss is possible if you have the following symptoms: you can't hear women, children, and birds; When watching TV and listening to the radio, the volume is very loud to hear clearly; When talking to people, you can't hear or misinterpret others' words, and when you interact with people in public places, you can hear voices but can't hear clearly.
