 note = {Trains and buses are equipped with hand straps for passengers to hold and prevent accidents when the vehicles are moving. Standing passengers hold straps hanging from metal pipe for support in crowded public transport. During a train run, a passenger’ s weight moves, causing straps to rub with the pipe they are looped around. In this case, a “creaking sound” occurs. This sound causes passengers to experience “unpleasantness” in crowded confines. We experimented using actual straps and pipes for detailed analysis. Sound of frictional contact between strap belt and pipe simulated from dynamic responses of a non-linear system was analyzed, and the following results were obtained.（1）This “creaking noise” is similar to an impulsive sound. It is generated from stick-slip motion between strap and pipe.（2）Its frequency is dominated by the natural frequency of the strap and the pipe tested.},
