title: [Temporary hearing threshold shift in policemen after firearm training].
abstract: BACKGROUND
  The paper involves exposure to noise of the State Police officers connected with the use of firearms. The noise generated by these weapons is of short duration and high intensity.
  
  
  METHODS
  The research was carried out during the sessions of firearm training of State Police officers to assess exposure to noise.
  
  
  RESULTS
  The values of the various investigations, both audiometric and phonometric, carried out made it possible to demonstrate a significant exposure and a temporary increase in the threshold, above the frequency of 6000 Hz.
  
  
  CONCLUSIONS
  Even taking account of the abatement from use of headphones, an exposure was demonstrated that was above the statutory limits, as was confirmed by the temporary hearing threshold shift.
