I am using this as a central page to share educational info on noise pollution caused by human actions and activities. Noise hurts sky, land, and underwater habitats of all species on Earth including humans.

I support environmental and community sound levels quiet enough to protect species at risk and protect human rights to communication and hearing health. I define noise objectively as sound levels higher than recommended World Health Organization internationally recommended guidelines.

Public Health Noise Limit Guidelines

< 40 dBA
Day-Night: Natural quiet with no amplified or manufactured sound sources, habitat conservation, sleep, rest, recovery, preschools, classrooms, hospital rooms
40 – 55 dBA
Day-Night: Risk of speech interference and/or discomfort for people with hearing health disabilities or quiet communication needs, e.g. tinnitus, hyperacusis, speech-in-noise loss, hearing loss, cognitive delays or declines, autism, hyperactivity, post concussion or head-injury, post-traumatic stress disorder, dementia.
Night: Increased risk of chronic mental and physical health conditions: e.g. low birth weight, delayed learning, delayed language, delayed reading, cognitive delays, autism, anxiety, depression, high blood pressure, heart attacks, strokes, obesity, Type 2 diabetes, dementia, early death
55 – 70 dBA
Day-Night: All of the above + speech interference for people with normal hearing.
> 70 dBA
Day-Night: All of the above + hearing health risk, e.g. hidden hearing loss, speech-in-noise loss, tinnitus, hyperacusis, temporary or permanent sensorineural hearing loss, accelerated age-related sensorineural hearing loss
