Low-frequency tones have the distinct advantage of penetrating solid materials allowing vehicle operators and nearby pedestrians to FEEL the sound waves.\u003c\/div\u003e\r\n\u003cdiv\u003e \u003c\/div\u003e\r\n\u003cdiv\u003e \u003c\/div\u003e\r\n\u003cdiv\u003e\u003cstrong\u003eSecondary System with Built-in Safety\u003c\/strong\u003e\u003c\/div\u003e\r\n\u003cdiv\u003eThe Rumbler system senses the primary siren tone signal and reduces the signals’ frequency by 75%. It then amplifies the sound through a pair of high output woofers. The system’s timer allows the tone to sound for eight seconds, providing a highly effective warning, and then automatically shuts off. The Rumbler is particularly effective when used in dense urban environments with heavy vehicle and pedestrian traffic.  \u003c\/div\u003e\r\n\u003cdiv\u003e \u003c\/div\u003e\r\n\u003cdiv\u003eA complete Rumbler traffic clearing system consists of an amplifier, with built-in timer and two subwoofers.
