Noise in weaving mills becomes much louder with increasing speed of weaving machine. One of the sources of the noise is the collision of healds caused by shedding motion on a loom. It was clarified in the previous report that the sound caused by shedding motion was significantly connected with heald motion during a period of shedding motion. In this report, vibration and noise characteristics when changing warp density are investigated using a short time fourier transform and high-speed camera in order to relate the sound to the heald motion in a period of shedding motion. As a result, it is found that the noise between upper and lower dead of shedding motion at low warp density is larger than the noise at high warp density. This is because the lateral movement of the heald after jumping become free due to low warp density and the collision energy of each heald is increased. [ABSTRACT FROM AUTHOR]
