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.
Much of noise pollution comes from transportation — including traffic, highways and railways — or industrial and manufacturing plants, experts say, but it can come from many sources. How is ...
Example of transportation noise and how it affects the community. 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 ...
Highway noise is today less affected by motor type, since the effects in higher speed are aerodynamic and tire noise related. Other contributions to the reduction of noise at the source are: improved tire tread designs for trucks in the 1970s, better shielding of diesel stacks in the 1980s, and local vehicle regulation of unmuffled vehicles.

Occupational noise is the amount of acoustic energy received by an employee's auditory system when they are working in the industry. Occupational noise, or industrial noise, is often a term used in occupational safety and health , as sustained exposure can cause permanent hearing damage.
Roadway noise is the most prevalent form of environmental noise.Pictured: São Paulo, Brazil. Roadway noise is the collective sound energy emanating from motor vehicles.It consists chiefly of road surface, tire, engine/transmission, aerodynamic, and braking elements.
