Effects of noise and vibration on operatives with machine interaction in manufacturing environments

Abstract

Human-machine interaction is an ordinary paradigm in the manufacturing industry. This area of business has to ensure high standard of safety levels in order to protect the operatives while performing their tasks. If the safety criteria are not met nor controlled, psychological disease and physical injuries can be developed in the working environments. The effects could lead to short or long-term diseases such as tinnitus or hearth attacks, based on the levels of stress. During the last decades, different methodologies have been developed to analyse and evaluate the parameters linked to the human-machine interaction. These methodologies include the biomechanics overload, noise and vibration. This paper deals with a case study as representative of the manufacturing sector. The noise and vibration levels of different machines have been extracted by a database of been measured on site by using a class 1 sound level meter. The purpose of the paper is to make a data analysis, assuming a long-term projection of the physical and psychological effects that could affect the operatives in case any criteria has not been met.

Generation and Characteristics of Construction Noise in Rail Transit Engineering Enclosure Structures

“…Their noise spectrum energy contribution not only concentrates in the high-frequency range but also displays high sound intensity. This poses a potential threat to the hearing and health of the staff involved in the construction process [60]. During this construction process, noise emissions can be significantly reduced without affecting productivity by selecting appropriate drill bits [61,62], piles [63], and saws, as well as adjusting the operation of concrete mixers [11].…”
