Traffic noise, particularly from vehicles, is the major contributor to noise pollution in urban environments.

Long-term exposure to noise pollution has been linked to hearing loss, cardiovascular diseases, and sleep disturbances, but it does not improve cognitive function.

Noise levels are typically measured in decibels (dB), which represent the relative loudness of a sound compared to a reference level.

Physical measures to control noise pollution include the use of noise barriers, such as soundproofing materials, walls, or vegetation, to block or absorb noise.

Noise pollution refers to the presence of unwanted or excessive sound that causes annoyance or harm to humans or wildlife.

Traffic noise is typically not a common source of noise pollution in industrial areas, where noise is primarily generated by industrial activities, machinery operation, and construction work.

Noise standards are established to define acceptable or tolerable noise levels in different environments, such as residential, commercial, or industrial areas.

Noise pollution can negatively impact wildlife by causing hearing loss, habitat displacement, and increased stress levels, but it does not typically improve communication among animals.

Noise zoning regulations aim to reduce noise levels in residential areas by restricting certain activities or land uses that generate excessive noise.

Non-physical measures to control noise pollution include education and awareness campaigns to promote responsible behavior and encourage the use of quieter technologies.

Noise annoyance refers to the subjective perception of noise as unpleasant or annoying, which can vary among individuals and contexts.

Traffic noise is typically not a major source of noise pollution in construction sites, where noise is primarily generated by machinery operation, blasting activities, and demolition work.

Noise control refers to the process of reducing or eliminating unwanted noise through various measures, such as physical barriers, soundproofing, and operational changes.

Occupational noise exposure can lead to hearing loss, tinnitus, and hypertension, but it does not typically improve sleep quality.

Noise limits are established to define the maximum permissible noise level allowed in a given environment or situation, beyond which noise pollution is considered harmful.
