Acoustical Evaluation of Combat Arms Firing Range, Grand Forks AFB, North Dakota
Abstract
An acoustical assessment was performed on the Combat Arms Firing Range at Grand Forks AFB in August 2014. It was determined that the noise in the firing range did not meet the definition of impulse noise for the M870 and M9 in accordance with Air Force Occupational Safety and Health (AFOSH) Standard 48-20 due to acoustical reflections. Conversely, the noise in the firing range met the definition of impulse noise for the M4 in accordance with AFOSH Standard 48-20. Due to the fact that training for all three weapons occurs in this facility, it was recommended that acoustical absorption be added to the walls to reduce the reverberant field.
