Abstract: 

Analyzing the sound resulting from a gunshot can help identify the type of gun used and can also lead to a better understanding of the impact of this sound on hearing. Exposure to gunshot sounds can cause hearing impairments. Measuring these sounds from various locations and analyzing them can improve the design of hearing protectors and help enact regulations to minimize the impact of gunshot sounds on hearing impairments. In this thesis, acoustic data was collected from different guns and a mortar for analysis. This thesis entails two types of analysis. The first is an image-based analysis method to take advantage of the recent advancement of image recognition techniques. A second type of analysis was conducted using a novel characterization method for characterizing acoustic attenuation properties that respects the spectral sensitivity of the human ear and preserves the energy in its octave bands at the same time.
