ABSTRACT:
A glass break simulator responds to a low-frequency sound component of the sound of breaking glass produced by striking the glass. The glass break simulator detects the low-frequency sound component and when an amplitude of the low-frequency sound component exceeds a predetermined threshold value, the simulator generates a high-frequency sound component by converting a digital representation of the high-frequency sound component into sound. The low-frequency sound component and the generated high-frequency sound component are directed at a glass break detector to test it, with the glass break detector responsive to both low and high-frequency sound components.
