Explanation

Noise pollution acts mainly through hearing and stress pathways rather than through the lungs.

Statement 1: loud background sound masks conversation, causing speech interference.

Statement 2: prolonged exposure damages the inner ear, causing hearing loss.

Statement 3 and Statement 5: chronic noise raises blood pressure and disturbs sleep, giving hypertension and insomnia.

Statement 4: respiratory disease is not a recognised effect of noise, so it is excluded.

India sets permissible noise limits by zone under the Noise Pollution Rules.
