NON-INVASIVE INVESTIGATION OF PROFESSIONAL
NOISE OVER THE WORKERS
Ther paper introduces a new investigation method for the noise action
over the worker in the industrial field. This method consists in the ECG
evaluation of the workers that are inside the industrial space during the
professional activity. The paper presents an experimental study of the noise
action on a sample of workers of different ages. They work in an industrial
workers space with 8 different machine tools, 8 hours per day, 5 days per
week. The paper looks to establish the impairment of workers’ occupational
noise. All of them were made in the morning, and at the end of the work each
day. Comparing the results of ECG measurements, pre and post exposure to
sound level above 80 dB, may establish the risk of cardiac disease in different
form of it.
