Noise Control Techniques Ppt. Layout modify noise source process, equipment, material act on sound wave (path of transmission) transmission loss absorption resonators/mufflers protect receiver planning/plant layout control noise before it exists specify quietest equipment at purchase obtain information from vendor on the sound power. If noise levels are above 90dba, osha requires engineering controls to reduce the noise in the workplace. This presentation is based on content presented at the 2007 mines safety roadshow held in october 2007. 3.absorb the sound with a light, porous material that soaks up sound waves.
Auditory stimulus or stimuli bearing no. 2.block the sound with a solid, heavy material that resists the transmission of sound waves. The following are 10 simple noise control techniques that have wide application across the whole of industry. Replace the sound source with a quieter one. The decibel is a logarithmic unit of measure so we cant simply add numbers.
