As we all know, we call the ability of the auditory organ to perceive sound as hearing, and the clinical evaluation of good or bad hearing is to find a standard that can be regulated by a number, and this is the role of “hearing threshold”. The patient’s hearing loss is more than 30 dB, that is, the hearing threshold of the frequency has increased by 30 dB, can be diagnosed as deaf. When the noise is very strong and the top of the spectrum changes a lot, jumping up and down and other noise damage to the ear, it will cause the hearing threshold to rise. So, what are the methods for patients to prevent hearing threshold rise? The following to briefly introduce: 1, noise damage to hearing, sudden exposure to firecrackers or say overnight, many people to K hall to HIGH, the day or every other day ear stuffiness, tinnitus, feeling hearing loss, this situation is very common. Especially not often to the K hall, not adapted to this environment of this kind of people, often the most likely to hear the damage. In this case, we suggest to follow the principle of sudden deafness and give nerve-nourishing, vasodilating, sleep-improving and sedative drugs in the hope that the cochlea can recover as soon as possible from the sound damage. It should be said that some patients have good results, but unfortunately, some of them are not able to return, which is acute sound damage. 2, because of the noise of the environment, the best way for workers who have chronic sound damage to cause noise deafness is to leave that environment and change the type of work. If it is not possible to do so for the time being, then you should wear ear protection devices, firstly, to reduce the noise of the working environment, and now many places that pay attention to labor protection should have them, such as the highways now have sound insulation panels erected on both sides to reduce the noise to the surrounding residents, especially the noise at night, which is very annoying, and sometimes it is not the damage to the hearing, but more to the emotions and the mental requirements. Many people in this environment for a long time, will lead to insomnia, leading to increased blood pressure, easy to anger, and even easy to anxiety and so on have, the noise is harmful to the whole body.
