Document Type and Number:
Japanese Patent JP3842937
Kind Code:
B
Abstract:
PROBLEM TO BE SOLVED: To provide a continuous impart-noise generating device capable of precisely measuring and evaluating a walking sound on a target floor part.
SOLUTION: This continuous impact-noise generating device has a pair of vertically movable impact-noise generators B, and a pair of cam means C for thrusting up each impact-noise generator B respectively and for dropping the impact-noise generator B by releasing thrusting-up, to thereby generate a collision impact noise on a measuring target floor part D.
