Exposure to loud noises can have harmful effects on health. Some example of adverse health effects are constant headaches and nausea. The prolonged exposure to a noisy environment can cause permanent hearing damage. These are just some of the direct effects of loud noises. A noisy environment is very stressful and stress has been linked to various health problems. This is the reason why there are regulations in place that limits the amount of noise generated by any operation.
Much like everything in the world, there are downsides to noise regulations. To certain businesses, these can make it difficult to acquire the needed permits and licenses to operate. A sound meter is used to determine the noise levels. If noise levels are over the limit, noise control measures must be implemented.
There are two ways to control noise. One method revolves around the source of noise. Replacing the old combustion engine with an electric motor is a good example of controlling the source of noise. This method can be expensive. There are cases in which nothing can be done with the source of noise. Such is the case with a fitness gym, in which noise from gym-goers grunting and dropping weights is impossible to stop.
The other method focuses on noise transmission. Going back to the fitness gym as an example, noise can be controlled by lining the walls with noise insulation materials. This way, all the noises generated are contained within the gym and are not transmitted outside to other offices or buildings.
