SINGLE SOUND ABSORBERS FOR NOISE REDUCTION IN THE INSTRUMENTATION TECHNICIAN WORKPLACE
https://doi.org/10.23947/2541-9129-2018-3-4-30-43
Abstract
The study of the workplace of instrumentation technician in LLC "Oil-Telecom" allowed us to identify the main harmful production factor. This is noise, that spreads from the oil pumping equipment and constantly acts on the worker. It
is established, that in this production the equivalent sound level is 86 dBA, when the normal level is not more than 80 dBA. Workers are exposed to noise for 8 hours per shift with two
technological breaks of 15 minutes in the first and second halves of the working day. The problem of noise reduction can be solved by placing single sound absorbers on the ceiling in the
working room. Thus, the aim of the study is to calculate their required number. As a result of the performed scientific work, it was found that the installation of 60 devices will reduce the
sound level to an acceptable level, and, consequently, the class of working conditions. In addition, the fatigue of workers will decrease, their health will improve, and productivity will increase.
