The Mythbusters attempt to construct a subwoofer with enough power to shatter the windows in a car. This is a great episode for exploring low-frequency sound and their effects. Kari, Grant, and Tory explore the myth that driving faster over bumps makes them less intense. Here, they also make a distinction between quantitative and qualitative data. Scientific concepts include sound waves, amplitude, frequency, hertz, decibels, pressure waves, decibel scale, sound amplification, rubber diaphragms, sound wave oscillation, suspension deflection, and qualitative vs. quantitative data comparisons.
