Study the same and answer the questions that follow: Given below is a representation of a kind of pollution (a scene showing heavy traffic, horns and loudspeakers). Study the same and answer the questions that follow:
Mention three harmful effects of this pollution on human health.
Topic: Effects of noise pollution
Answer
- It interrupts CONCENTRATION and disturbs peace of mind, causing irritability and mental stress.
- It disturbs SLEEP and leads to nervous irritability, headache and hypertension.
- It lowers the EFFICIENCY OF WORK, and prolonged exposure to loud noise damages the hair cells of the organ of Corti, causing partial or permanent DEAFNESS.
THREE effects, and they should differ in kind — mental, physiological and on hearing.
THE DEAFNESS POINT is the most specifically biological and worth including: the damage is SENSORINEURAL, since the hair cells of the organ of Corti do NOT regenerate. Unlike a torn eardrum, the loss is PERMANENT — which is exactly what the 2026 paper examines through its quarry worker.
The damage ACCUMULATES over years above about 80 decibels, which is why industrial deafness develops gradually rather than suddenly, and why the person often does not notice until it is irreversible.
