Noise disease

Noise disease is a systemic disease that mainly affects the auditory organs and is accompanied by external auditory system reactions. The occurrence of symptoms and signs is related to the intensity, frequency, contact time and individual sensitivity to noise. When various sounds of different frequencies and different intensities are mixed in a chaotic manner, it can produce distracting noises that make it difficult to work and rest at ease; in some specific cases, even amused music may become one. This kind of noise is physiologically speaking. Any sound that is not needed, which affects people's life, work, and study, and interferes with it is called noise. Noise mainly damages the human hearing organs. Long-term exposure to high-intensity noise not only damages the auditory organs, but also affects the central nervous system, cardiovascular system, endocrine system, and digestive system to varying degrees. The specific effect of noise mainly causes damage to the auditory system; its non-specific effect is manifested as the effect on the external auditory system. Therefore, clinically, noise diseases are divided into two types, one is "specific" noise disease; the other is "non-specific" noise disease. When noise only causes "Curtis's" damage to the auditory organ, it is a "specific" noise disease; when noise acts on various organs of the body, causing damage to the autonomic nervous system and cardiovascular system, it is "non-specific" noise. disease.
