Effects of noise on operatives with machine interaction in manufacturing environments

Human-machine interaction is an ordinary paradigm in the manufacturing industry. This area of business has to ensure high level of safety in order to protect the operatives while performing their tasks. When 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 illnesses such as tinnitus or hearth attacks, in relation to the levels of stress. During the last decades, different methodologies have been developed to analyse and evaluate the parameters linked to the humanmachine interaction. These methodologies include the biomechanics overload, the 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 carry out a data analysis, assuming a long-term projection of the physical and psychological effects that could affect the operatives in case of any criteria has not been met.
