This paper compares the Sound Pressure Levels (SPL) generated from the waterjet cutting process between an open catcher tank and an adjustable water level catcher tank (also known as water catcher tank) for two dimensional cutting. It also provides practical measurements of noise levels at different pressures using various cutting nozzle sizes. Further, by continuously monitoring the cutting activities, this paper provides the waterjet user with useful information that can best determine the allowable daily exposure of the operator to the noise level. As a result, the waterjet shops can assess the safety measures and standards that they have to practice, irrespective of the type of job.
