Turbocharger Noise Reduction on Ships
- 71 Downloads
Excessive noise can cause irreversible hearing impairment. The realisation that equipment manufacturers can make a significant contribution to this aspect of health and safety for ships’ crews, especially those in machine rooms, has been a major incentive for work carried out by ABB Turbo Systems to reduce noise emissions from turbochargers on large marine engines.
At the beginning of the new Century the World Health Organization reported that excessive noise is one of the most common occupational hazards. In general, exposure levels above 85 dB are considered hazardous. Such levels are often found in the mining, manufacturing and construction industries, particularly in developing countries . Noise-induced hearing loss is both irreversible and permanent but also entirely preventable. In fact, a large part of occupational noise exposure can be minimised by reducing noise generation at its source , and original equipment manufacturers (OEMs) in the maritime industry...
