When it comes to noise, otologists and previous patients immediately think of a significant drop in pure tone audiometry curve at 4000 Hz. When asked about medical history, patients have a long history of exposure to high frequency noise. The longer the period, the more difficult it is to treat, especially the accompanying noisy tinnitus, which is unbearable for the patient. Nowadays, the incidence of noisy tinnitus has decreased significantly due to the publicity on the dangers of noisy tinnitus and the improvement of people’s awareness of prevention. However, with the dense urban population and the obvious increase in the number of vehicles, we see that primary and secondary schools and even college students and working young people have a device that can be used to listen to their ears at all times. Therefore, the long-term stimulation of such low and medium frequencies not only causes the cochlea to suffer from auditory fatigue, but also causes tinnitus and low and medium frequency hearing loss, as well as mental fatigue and mental symptoms of distraction. In our outpatient cases of tinnitus and deafness, it is obvious that many high school students and young workers suffer from such diseases, which are suspected to be caused by viral infections at first, but after laboratory tests are ruled out, we have to consider the damage caused by such long-term low and medium frequency noise. This kind of damage, early detection, early treatment, the effect is significant, but more should advocate early prevention, as far as possible to reduce the stimulation of low and medium frequency, but also pay attention to the “Walkman do not listen to the Walkman”. Because the ear is one of the sensory organs of our body that has been with us for the longest time, please cherish it.
