![]() ![]() Noise can also cause stress and disturbs the balance of predator – prey detection.Īn impact of noise on animals is an increased risk of untimely death. Overexposure to noise can lead to temporary or permanent hearing loss in many animals. Noise also has a harmful effect on animal life. ![]() Continuous exposure to severe levels of noise can cause hypertension, stress, irregular sleep patterns, etc. Hearing loss is the first and most important effect of noise.Īpart from physiological health, noise also affects the psychological behavior of humans. Several institutions and organizations have formally recognized noise as a threat to the health and well-being of humans. Noise Pollution is the latest category of environmental pollutants (the other being air and water). If you live near or work in an industrial area, then there are several sources of noise there. Household works and chores, transportation, and construction are some noises everyone encounters frequently. But the same music at the same volume may be noise to another person. One person may enjoy listening to heavy metal music at one volume. In terms of public health concerns, noise is a sound that has enough intensity to cause hearing damage We can also define Noise as a sound that interferes with speech and hearing. Here, the term ‘unwanted’ means that it has adverse health effects on human and animal hearing. What is Noise?Īs we already mentioned before, any unwanted sound is Noise. Finally, we need a receiver, an ear in our case, to absorb the energy. These sound waves travel through a medium. We need a source or vibrating object to transmit sound waves. Sound is a form of energy produced by longitudinal mechanical waves in solids, liquids, or gases. Our ear detects these pressure fluctuations happening above and below the atmospheric pressure and creates the sensation of hearing. The movement of air particles will result in a fluctuation of atmospheric pressure. When a source induces vibrations in the air, it is actually producing an alternating band of dense and sparse particles of air. The ‘Sound’ we hear is the result of pressure variation in the air or any medium. After all, Noise is nothing but unwanted Sound. She does have to turn the TV up a good bit, (The TV is still quieter than her parents listen to their TV normally.) We do not have kids though, if that is a concern.Before understanding Noise, we need to first know a little bit about Sound. My point, is that regardless of what you purchase, it's going to be LOUD, it's not the only tool in the shop and actually runs a lot less than most of my other power tools.Įdit: I'll add - I run mine (DW745X) in the basement with a laguna 1.5HP cyclone DC and my wife can watch TV directly above it with just floor joists, the subfloor and hardwood flooring. My planer runs for about 30-40 min when I'm processing rough lumber and then occasionally for maybe a minute or two when I'm getting to final thickness. 3db of sound pressure is actually a double in sound pressure levels, but it actually takes ~3 times the sound pressure to have a human perceivable twice as loud. The earlier post about 10db less being 50% quieter is still 50% of LOUD leaving just LOUD. Unless you're running it for hours at a time the noise from any of them, while loud is going to be loud regardless. I'd look at it this way… Buy the planer you want, don't purchase based on how loud/quiet it is. If members would enter the information in the order seen below I'd be happy to merge the results and share them in a spreadsheet.Ĭutter type: e.g., 2-knife or helical headĭust collection on during decibel measurement?: e.g., yes/noĭust collection type: e.g., Rigid shop vac or 2 HP Oneida cyclone Please mention if and what type of dust collection you employed during the test. Just leave the phone atop your planer and we'll have fairly comparable results. Would members please consider planing in one pass 1/16" from a 6" wide piece of pine or poplar, and post the decibel levels in the reply section?Ī decibel meter can be downloaded free on any smartphone. So I have this idea for crowdsourcing this enquiry: Actual decibel levels for portable planers are very hard to come by. In the interests of family happiness I need the quietest portable planer possible.
