Environmental Noise Monitors
Noise is one of the most complained about aspects of the environment, as not only does it have the potential to affect quality of life, it can also be difficult to monitor and therefore control. This type of noise is generally called environmental noise. There are many man-made sources of environmental noise, such as wind turbines, industrial sites, roads and traffic etc. If you are looking for equipment to measure noise in the workplace, look at sound level meters.
