The Measurement of Low Frequency Impedance Using an Impedance Tube
Journal of Low Frequency Noise, Vibration and Active Control, 1998 An accurate and reliable prediction of car interior noise would be a significant step towards improving the design of car body panels and trim for a quieter vehicle. Automobile noise is dominated by low frequencies, from 50 to 300 Hz and therefore a technique is necessary to measure acoustic impedance of the trim materials at low frequencies.
