5 Test Setup

This section describes the test setup for the verification of this glass-breakage detector. Various glass-breakage test files were obtained from the sound effects vendor sounddogs.com. Some of the tests were performed with increased sound level of the original sound files to ensure that all sound files have nearly the same sound pressure level. A specified sound level is measured at a certain distance from the center of the membrane of the main box while a particular sine test tone is replayed. Figure 14 through Figure 16 show the measurement setup.
