Abstract:Noise affects the cruise comfort. The noise control technology is an effective to denoise. Experiment on cruise compartment is utilized to study the effectivity of denoise technology. An actual cruise compartment with two decks accommodating two rooms is established and two types of denoise materials and corresponding process are designed: the damper + steel tile, and damper + steel tile + Mineral wool. The noise measurements on established noise experimental model are conducted following the terms in rules. The measurement results show that the noises under two types denoise materials are below 45 dB which meets the requirement of rules, and that the sound insulation is above 30 dB when the frequencies are above 160 Hz, validating the adopted noise control technologies.
