How to test whether your hearing is normal?
all together all all all all all all all all together all make all the difference.2. Does your family often complain that you turn the volume up too loud when watching TV?
3. Do you have difficulty communicating with people in noisy environments?
4. Do you have difficulty hearing clearly when there are multiple people talking?
5. Do you often have difficulty hearing what the other party is saying when talking on the phone?
6. Are you unable to accurately determine the direction of the sound source?
7. Can you hear others speaking, but cannot understand what they say?
8. Do you often misunderstand what others say?
If you answered “yes” to 2 or more of the above 8 questions, you may have symptoms of hearing loss! However, to further confirm, the best way is to go to a hospital or hearing center for a detailed hearing examination.
Self-test is only preliminary, regular check-up is the best way. Although the above two methods can preliminarily self-test your hearing, the best way is to go to the hospital or fitting center for regular check-ups to ensure early hearing. Pay attention to early prevention.
According to the classification standards of the World Health Organization:
The normal hearing range is 0-25dBHL. Natural sounds such as wind and rustling leaves can be heard. . There are varying degrees of hearing loss above 25dB.
● 26-40dBHL is a mild hearing loss, and it is difficult to distinguish small sounds such as wind blowing leaves;
● 41-60dBHL is a moderate hearing loss, daily communication is affected, and speech can be heard but not clearly. ;
; There is no perception. We can self-test whether our hearing is within the normal range through the hearing grading standards.
The decibel rating mentioned earlier represents the perception of sound size. In addition, when testing hearing, we also need frequency distribution, that is, the perception of sound. Thickness and fineness of perception, for example, some people hear boys' voices more clearly, while some people hear girls' voices more clearly, are related to frequency. General frequencies can be divided into low frequencies, medium frequencies and high frequencies.
● 125-1000 (Hz) is a low frequency, like the thick and thick sound of the gay male,
● 1000-2500 (Hz) belongs to the intermediate frequency, most of the sounds are concentrated at this stage, which reflects the reflection of it. It is the intelligibility and brightness of the sound.
● Above 2500 (HZ) are high-frequency, crisp and thin sounds, such as bird chirping, phone ringing, etc.
● We have encountered in our work that the mid and low frequencies are normal but the high frequencies are lost. In daily life, it may be extremely difficult to hear the sounds of water and birds.
