title: Exposure to noise in orthopaedic theatres--do we need protection?
abstract: OBJECTIVE
  To detect noise levels, generated by high-powered tools in orthopaedic theatres at varying distances from the operating site, and its impact on hearing in staff and patients.
  
  
  METHODS
  Sound-level meter was used to measure the sound level generated by various high-powered tools in routine orthopaedic procedures, at varying distances from the operating site. These recorded noise levels were compared against the UK noise safety guidelines.
  
  
  RESULTS
  We found that the noise generated was often significantly higher than the safety guidelines.
  
  
  CONCLUSIONS
  Noise levels in orthopaedic theatres can be at unacceptable levels, which could potentially lead to hearing problems in the staff and patients. We believe that all patients, especially the elderly patients, (who are more prone to hearing problems) should have hearing protection during orthopaedic operations that use high-powered tools. Surgeons and scrubbed theatre staff should take precautions.
