Noise pollution health effects – UGC NET Question

Chronic exposure to loud noise can damage the delicate structures of the inner ear, leading to partial or permanent hearing loss. It can also trigger physiological stress responses, elevate blood pressure and interfere with normal sleep patterns and cognitive performance. These combined effects make noise pollution a serious public health issue, particularly in urban and occupational settings.

Option A:
Option A is incorrect because long-term noise exposure tends to reduce concentration and disturb sleep rather than improve them.

Option B:
Option B is correct because it lists well-documented health impacts of noise, including hearing impairment, stress and sleep disturbances.

Option C:
Option C is incorrect because high noise levels often hinder clear communication and may lead to social irritation or conflict instead of enhancing interaction.

Option D:
Option D is incorrect since noise exposure does not confer immunity from cardiovascular diseases; in fact, it is associated with increased cardiovascular risk through stress mechanisms.
