NOISE SURVEYS

Noise is one of the most prevalent occupational health hazards found in the workplace. Prolonged exposure to excessive noise can cause Noise Induced Hearing Loss (NIHL) commonly known as Noise Induced Deafness (NID). NID will ultimately reduce workers concentration and inhibit communications, which may escalate the risk of injury or even death. Hence accurate noise monitoring is an essential factor of a hearing conservation program. Noise monitoring will ascertain the best appropriate practice to reduce noise exposure and will help to determine the most appropriate type of hearing protector to use.

Using our new PULSAR NOVA MODEL 45 high performance sound level meter (compliant with IEC 61672-1:2002 - Class 1) which successfully combines the latest technology in noise measurement methods with ease of use and durability, UMC can clearly identify areas of potential high noise and provide recommendations for solving the high noise level conformed to the international standards. Noise monitoring includes:

  • Identification of work areas with excessive noise
  • Identification of individual noise sources which contribute to the excessive noise in work areas (e.g. equipment, machines, processes, operations and work activities)
  • Monitoring the noise exposure levels to individual employees working in the excessive noise areas
  • Creation of noise monitoring reports
  • Noise mapping of work areas with excessive noise

Typical areas of application include:

  • Onshore and offshore marine objects
  • Shipbuilding industry
  • Building and construction
  • Manufacturing
