Part 9: The end result of the sound insulation and anti-drumming of a Hummer H1

Showcase Hummer H1 Part 9: Sound Insulation and Anti-drumming

In previous blog posts you have been able to read how we processed a Hummer H1 by applying anti-drumming, sound insulation and sound absorption. In order to measure the effect of our adaptions we carried out another sound measurement, using the same calibrated measurement equipment. The car is still stripped of its interior and the measurement is carried out on the same route as during the sound measurement of part 1. The result: an attenuation of 13 dB!
