Acoustical Evaluation of Combat Arms Firing Range, Whiteman AFB, Missouri

An acoustical assessment was performed on the Combat Arms Firing Range at Whiteman AFB in April 2013. It was determined that the noise in the firing range met the definition of impulse noise in AFOSH Standard 48-20; however, CATM instructors and students are still potentially exposed to peak sound pressure levels that exceed the allowable limits of AFOSH Standard 48-20. Therefore, it was recommended that hearing protection, either single or double, be worn during weapons live-fire training.
