Method of Deck Noise Invasion Part of Verifying Effect of Noise Decrease Measures

Naoto TAGAWA, Katsuya YAMAMOTO


  We developed a method to verify an effective range and its effect for noise abatement within train vehicles by comparisons of changes in the noise level as measured under the following tests. First, by providing a speaker that generate penetrative sounds from an exterior of a vehicle, and with a vibration exciter generating solid bo‚’ne sound of the vehicle both of which adversely affect the vehicle deck.
  Second, floors, sides and ceilings of the vehicle deck all of which become a route of noise provided with insulation materials to reduce the noise level.
