How to look at the pure tone test chart[What is the result of pure tone test?]

How to look at the pure tone test chart? I spent a lot of money to do a pure tone test but I can’t read the test results. What do you think of pure tone test results? Today, I heard a little edited to give you a detailed introduction to the pure tone test chart:

First understand some common sense terms on the audiogram:
◎ Frequency (Hz, Hz): pitch, the unit is “Her”. The lower the number, the lower the sound.
◎Language area: The volume and frequency range of general daily conversations fall within this gray area.
◎ Hearing level (decibel, dB): The volume of the audible volume. The larger the number, the greater the volume.
Hearing lossdegree:
● Normal hearing = less than 25 decibel
● Mild = 20 ~ 40 decibel
● Moderate = 40 ~ 55 Decibel
● Moderate to Heavy = 55 ~ 70 Decibel
● Severity = 70 ~ 90 Decibel
● Extremely heavy = greater than 90 decibel
Audiologists recommend that hearing aids should be selected in time for hearing loss above 45 decibels.
The red circle on this audiogram represents the hearing condition of the right ear of the subject. As shown in the figure, the hearing level of each frequency is 70 decibels, that is, the sound is as large as 70 decibels.
The yellow “X” on this audiogram represents the hearing condition of the subject’s left ear. As shown in the figure, in the part of the frequency 250 Hz to 1000 Hz, the hearing degree of the left ear of the subject is 80 decibel, and in the part of the frequency 2000 Hz to 8000 Hz, the hearing degree of the left ear of the subject is 90 decibel.
Now let’s take a look at the average hearing of the left and right ears of the subject. The average hearing is calculated as follows:
Add the 500 Hz, 1000 Hz, 2000 Hz hearing levels and divide by three.
Average hearing value of the right ear:
70 decibel (500 Hz) + 70 decibel (1000 Hz) + 70 decibel (2000 Hz) = 210 decibel
210 decibel / 3 = 70 decibel
Average hearing value of the left ear:
80 decibel (500 Hz) + 80 decibel (1000 Hz) + 90 decibel (2000 Hz) = 250 decibel
250 decibel / 3 = 83 decibel
The above “A” symbol on the audiogram indicates the subject’s reaction to the sound after wearing the hearing aid. After the sound is amplified by the hearing aid, the subject’s response to each frequency is between 35 and 50 decibels. Will you look at your audiogram now?
