With the continuous progress of modern medical technology, physical examination has become a very important way of health management. Listening is one of the most important indexes in physical examination. For the measurement of hearing, we need to use the unit of hearing M, which can measure the sensitivity and accuracy of human auditory organs when listening to sounds. M unit of hearing is actually an acoustic physical quantity, and its unit is decibel (dB), which is used to describe the intensity of sound.
During the hearing examination, after the machine prompt sounds, the doctor will ask the subjects to respond to the direction and size of the sound according to different volume and tone. During the test, the doctor can accurately measure the auditory index of the subjects through auditory M units. It is worth noting that because people's listening factors are influenced by many factors such as age and environment, the listening standards of different age groups will be different.
Listening is very important to one's health. If a person suffers from hearing loss, it will affect his daily activities, such as his performance in study and work. Therefore, it is very necessary for people of different ages to have regular listening tests. Through hearing examination, it can be found and treated in time to avoid the adverse effects of hearing problems on physical and mental health.
