Noise health effects are the physical and psychological health consequences of regular exposure to consistent elevated sound levels. Noise from traffic, in particular, is considered by the World Health Organization to be one of the worst environmental stressors for humans, second only to air pollution. [2]
Electric and hybrid vehicles could reduce noise pollution, but only if those vehicles make up a high proportion of total vehicles on the road; even if traffic in an urban area reached a makeup of fifty percent electric vehicles, the overall noise reduction achieved would only be a few decibels and would be barely noticeable.

Note: The complete anatomy of the human ear is extensive, and can be divided into the inner ear and outer ear. The remainder of this article mainly references the cochlea, outer hair cells, and organ of Corti. In general, structural damages to any anatomical part of the human ear can cause hearing-related problems.
Turning existing city infrastructure green by installing plants can filter out fine dust and noise, reduce urban heat island effects, and even reduce stress. All it takes is regreening 20 percent ...
Noise-cancelling headphones and sound-isolating earphones can help one avoid turning the volume up to overcome loud background noise. Sound measurement apps can help one find out how loud sounds are. If not measuring the sound levels, a good rule of thumb is that sounds are potentially hazardous if it is necessary to speak in a raised voice to ...
Lin et al., conducted an experiment in Taiwan that tested the effect of generation of reactive oxygen species on temporary threshold shift and noise-induced hearing loss. [11] [12] Subjects were employees at a steel manufacturing company and each one was assessed for personal noise exposure during work shifts. Statistical analysis yielded a ...
Noise pollution, or sound pollution, is the propagation of noise or sound with potential harmful effects on humans and animals. The source of outdoor noise worldwide is mainly caused by machines, transport and propagation systems.
Environmental noise is an accumulation of noise pollution that occurs outside. This noise can be caused by transport, industrial, and recreational activities. [1] Noise is frequently described as 'unwanted sound'. Within this context, environmental noise is generally present in some form in all areas of human, animal, or environmental activity.
