Noise hazards have become one of the main hazards in the world today. Noise detection pollution has been considered one of the top seven public hazards in the world. Let me learn about what is noise occupational disease.
Noise is widely present in people's work processes and environments. Noise deafness is one of the common occupational diseases. Working in high noise environments for a long time will cause workers to suffer from occupational noise deafness.
Diagnostic principles for occupational noise deafness
Pure tone auditory is sensorineural hearing loss. According to a clear history of occupational noise exposure, there are conscious hearing loss or tinnitus symptoms, combined with years of occupational health examination data and on-site health investigations, other causes of hearing damage can be ruled out, and sensorineural hearing loss can be diagnosed.
Observing objects
Average hearing threshold at high frequency of binaural (3000Hz, 4000Hz, 6000Hz) is ≥40dB (HL).
Diagnosis and diagnosis classification
Continuous noise exposure for more than 3 years, pure tone auditory is sensorineural hearing loss, and hearing loss is a high-frequency decline type. Classified diagnosis is made based on the average hearing threshold of better whisper frequency (500Hz, 1000HZ, 2000HZ).
1. Mild noise deafness: 26dB-40dB(HL)
2. Moderate noise deafness: 41dB-55dB(HL)
3. Severe noise deafness: ≥56dB(HL)
Management principles
1. The subject to be observed does not need to leave the noisy workplace, except those with tinnitus.
2. Patients with mild, moderate and severe noise deafness should stay away from noisy workplaces. If they need to undergo labor capacity assessment, they should be treated according to GB/T16180.
3. Patients with severe noise deafness should wear hearing aids.
4. People with noise sensitivity (i.e., those with normal hearing before joining the job, working in a noisy environment for one year, high frequency bands of 3000hz, 4000hz, 6000Hz, and any ears up to 65db (HL)) should stay away from noisy workplaces.
