[Temporary hearing threshold shift in policemen after firearm training].

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.

CONCLUSION

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.
