Circular Resonant Design

Vigilant's engineers have created a better, higher performance acoustic design. Sound waves travel outward from a speaker. The PPS-13BL is circular (like a speaker) so that the sound can build volume and crescendo from the speaker on the front of the device. Similar to an ambulance siren that projects the sound forcefully, the new design saturates the area in front of the PPS-13BL circular speaker with piercing resonating sound.

In physics, resonance is a phenomenon in which a vibrating system or external force drives another system to oscillate with greater amplitude at specific frequencies. Frequencies at which the response amplitude is a relative maximum are known as the system's resonant frequencies or resonance frequencies. The PPS-13BL is built to extract the maximum resonance of the alarm at a frequency perfectly tuned to create what your ear will hear as the loudest alarm noise possible from it's palm sized case. The design of the PPS-13BL produces more resonance (prolongation of sound) than a typical alarm. The result is exactly what you want it to be - a cringe-worthy, painfully loud emergency alarm.
