It is known that noise pollution has both physiological and psychological effects on human health.
The human body reacts completely automatically and unconsciously when it hears sudden and loud sounds. For this reason, working in a noisy environment will pose a risk for the personnel.
Noise measurements are made to identify and eliminate noise risks.
Noise parameters can be described as sound power, sound intensity and sound pressure.
Sound power (w): It is the measure of sound energy emitted from the source per unit time. Each machine has a unique sound power level.
Sound intensity (w/m2): It is defined as the vectorial measure of acoustic energy passing through a unit area.
Sound pressure (pa) : It is defined as a fluctuating pressure caused by sound above the static pressure.
The machines within the scope of the 2000/14/EU Noise Emission Regulation are as follows.
