Question 1: I am a factory worker. After pure tone hearing threshold test, whether the following results belong to mild hearing loss, but the high frequency damage has reached moderate level. It is recommended to have a hearing test every three months, and intervene in time if there is any problem.

Question 2: What is the normal value of pure tone hearing threshold average/articulation index? If this situation is normal, it is generally above 20 decibels, which means it is normal, and it is abnormal if it exceeds it!

Question 3: Is there anything wrong with the results of pure tone hearing threshold test? I feel that my hearing is not as good as before. Pure tone hearing threshold test shows that the hearing threshold is less than 25DB for normal hearing. R stands for right ear and l stands for left ear.

Question 4: The basic concept of pure tone hearing threshold test Pure tone hearing threshold test is the lightest sound that the tested ear can hear for pure tones of different frequencies, and it is the standard for judging hearing sensitivity. According to GB7583-87, someone's hearing threshold is the minimum sound pressure level that can correctly cause hearing with a specified sound signal under specified conditions, which is more than half of the times in repeated tests. At the same time, pure tone audiometry is a modern popular listening test method, which can be used both qualitatively and quantitatively to judge and analyze the degree and nature of hearing loss.
