Noise is a technological metabolism by-product, representing one of the most important discomfort factors for personnel that work in energetic coal extracting and preparation processes.

Being aware of the general risks specific to energetic coal extracting and preparation activities, generated by exposure to noise, helps quantifying the effects upon workers, such as: blanking, auditory fatigue, sonorous trauma, partial loss of hearing, professional deafness.

Prolonged exposure to high intensity noise may lead, in time, to professional deafness. Unlike auditory fatigue, which is a transitory and reversible phenomenon, noise caused deafness is characterized by definitive and irreversible loss of hearing.

The number of people exposed to noise is continuously rising because of the equipment’s increasing work speed and power and increased mechanization.

The current paper analyzes the evolution of the main sources of noise specific to energetic coal extracting and preparation processes, depending on maintenance and refurbishment.
