In today’s modern world, with the increased population and urbanisation, noise pollution has also increased. The workplace and living spaces has also become more crowded. The main elements contributing to indoor noise problem involve both indoor and outdoor noise sources, affecting sleep habits and quality of life.
The use of equipment such as high – tech entertainment rooms, pinging computers, blaring stereos and ringing phones also contributes the cacophony of indoor noise.
Being exposed to high levels of noise affects everyone, a little differently. Children in general are more sensitive to excessive levels of noise, along with chronically ill or elderly people. Adults who work in especially noisy environments also experience higher level of stress and fatigue. Disturbed sleep patterns due to noise pollution can mean higher medical bills and more seriously for children, impaired childhood development.
WHO has list of recommended noise levels for different types of interior spaces. WHO recommends less than 30db (A) of noise for bedrooms and less than 35db (A) in classrooms to allow for good teaching and learning environments.
