Adverse effects of noise

Noise is one of the most common occupational health hazards that employees are exposed to daily. At workplaces, sources can vary from processes, operations to activities. Prolonged exposure may cause hearing damages, leading to hearing loss, which also known as noise-induced hearing loss or noise-induced deafness (NID).


Like any other occupational health condition, damages to hearing sensitivity dramatically decreases the quality of life as a result of social isolation, communication difficulties in personal relationships.


Excessive exposure to a high level of noise may also result in;

  • Tinnitus – also characterised as continuous ringing in the ear
  • Acoustic trauma – temporary or permanent hearing loss due to exposure to sudden and very loud noise, such as explosion
  • Annoyance
  • Stress
  • Anxiety
  • Headaches
  • Coordination difficulties
  • Interference with communication and perception of warning signals


To protect employees from the side effects of exposure to noise should be effectively controlled by the employer.
