Humans can hear sounds between 0 and 140 decibels.The general level of noise ranges from 60 to 80 db. Noise affects performance and leads to high levels of stress. Recommended background noise level should not exceed 45db. Noisy spaces above the suggested threshold negatively affect concentration, increase stress levels and eventually lead to negative effect on health and well-being of people working or living in noisy spaces. Severe and prolonged exposure to noise may also lead to loss of hearing. The solution to treat noise is through use of acoustic/absorptive materials.
