UGC NET Questions (Paper – 1)

The auditory system,which includes the ear and related neural pathways,is directly affected by continuous exposure to high noise levels. Such exposure can lead to temporary or permanent hearing loss,tinnitus and other auditory disorders. The stem explicitly mentions damage from environmental noise,so the auditory system is the correct answer. Therefore Option C is appropriate.

Option A:
Digestive problems can sometimes be indirectly influenced by stress but are not the primary health outcome of noise exposure. The main clinical concern with noise pollution is hearing impairment rather than digestive system disorders,so Option A is not accurate here.

Option B:
The skeletal system involves bones and joints and is generally not affected by noise levels in the environment. Noise does not directly weaken or damage bones,so this option does not match the primary impact described in the question.

Option C:
The auditory system is highly sensitive to sound pressure levels and duration of exposure. Occupational and urban noise regulations are designed specifically to protect this system from long term damage. This explanation fits the content of the stem.

Option D:
The reproductive system is not directly harmed by typical environmental noise levels,although extreme stress can influence many body systems. However,this is not the main issue addressed in noise pollution studies,so Option D is not the best choice.
