We know that according to the location of the ear lesion, hearing loss can be divided into conductive, sensorineural and mixed hearing loss.
According to the hearing loss at different frequencies, it can be divided into high-frequency hearing loss and low-frequency hearing loss.
So, what is the difference between high-frequency hearing loss and low-frequency hearing loss? How can you simply determine which type you belong to?
First of all, we need to understand that the "frequency" mentioned here refers to "frequency".
Frequency is the number of times an object vibrates in a second, in hertz (abbreviated as Hz).
The sound range that our human ear can hear is within 20 to 20000Hz.
Judging from the display diagram provided by Bertone, people generally speak at about 1000Hz, children cry and thunder at about 2000Hz, and birds and telephone ringtones around 6000Hz.
We can use 500Hz and 2000Hz as the dividing line, below 500Hz bias to low frequencies, above 2000Hz biased to high frequencies (for reference, the standard division does not yet have a uniformly accepted value).
According to the above division, the puppy's call belongs to the low frequency, and the bird's call belongs to the high frequency.
The difference between men and women
In general, it can be understood that the voice of the male speaker belongs to the low frequency (low), and the female voice belongs to the high frequency (sharp, higher pitched).
If a person listens to a woman much more than a man, he is likely to fall under high-frequency hearing loss.
Single-player chat/multiplayer chat
If a person is low-frequency hearing loss, then when he communicates with other people alone, he will generally not have a lot of trouble and can understand most of the content.
If it is a high-frequency hearing loss, it is much more difficult to speak and communicate, often need to listen carefully, and there may be a situation of "hearing, not understanding".
Although there are differences in sound acquisition between low-frequency and high-frequency hearing loss, if you are in a noisy environment, both will generally be inaudible.
Different types of music
Instruments with low sound quality such as drums, cello, erhu, tuba and so on can generally be summarized as low-frequency fields.
Instruments such as pianos, piccolos, violins, etc., can reach the high-frequency field.
If a person listens to Han Hong singing, the words are not very clear, but listen to Eason Chan singing more clearly, then he is likely to have high-frequency hearing loss.
It should be emphasized that high-frequency and low-frequency hearing loss people only have different receptivity to different frequencies of sound, which does not mean that they cannot hear it completely.
After reading the above, can you tell if you are high-frequency hearing loss or low-frequency hearing loss?
