Recently, the hospital's ENT experts visited the construction site for workers' medical examinations and found that multiple workers had hearing problems of varying degrees. China Labor Insurance Network Diffused Silicon Pressure Sensor The diffusion silicon Pressure Sensor adopts the diffusion silicon piezoresistive pressure sensor with stainless steel isolation film as the signal measuring element, the signal processing circuit is located in the stainless steel housing, the sensor signal is converted into standard 4-20mA current or RS485 signal output through the professional signal conditioning circuit. Widely used in petroleum, chemical, metallurgy, electric power and other industrial process on-site measurement and control.

After examination by experts, it was found that most of the more than 20 workers have different degrees of neurological tinnitus and hearing loss. He reminded that the noise on the construction site, the sound of the machines in the factory, the sound of firecrackers that rang in his ear, the sound in the KTV, etc. all had a greater impact on hearing.
There are two kinds of temporary and permanent hearing loss caused by noise. Delayed treatment after symptoms such as tinnitus, hearing loss, and headache after noise stimulation may result in permanent hearing loss, but also endocrine, neurological, cardiovascular, and other symptoms of the digestive system.
For people who work in noise environments for a long time, it is best to wear earplugs or earmuffs. When you take a train through the tunnel, take off or landing planes or set off firecrackers, wearing these products can also effectively protect your hearing.
