Noisy Vacuum Cleaners
Seems like everything is noisy these days-cars, construction, schools, concerts etc. Every once in a while, you just want to have some quiet. Noise protection is very important. Noise is unwanted noise and is basically a pollutant and a hazard to our health and hearing.
Noise levels are measured in decibels (dB). The higher the decibel level, the louder the noise. Sounds louder than 80 decibels are considered potentially hazardous. The noise chart below gives an idea of average decibel levels for everyday sounds around you. (source)
