w Summary writing. Read the passage given in Q. 4 A) and write the ( Summary of it and suggest a suitble title for it. aThe planting of popular trees, like the casuarina, tamarind, banyan and neem, appears to give a

possible method of reducing noise pollution in towns. For , according to a study by a team of

doctors and technicians at the Institute of Oto-Reino Laryngology in Chennai Medical College,

these trees and certain other shrubs strongly reduce sound levels, particularly the din produced

by the continuous flow of automobiles.

Under a project of the Science and Technology Department of the Central Government, the

institute conducted investigation into the effect of noise pollution among workers in four cities

of Tamil Nadu and Kerala. It was found that exposure of these persons to traffic noise resulted

in a considerable loss of hearing capacity over a period of time. The study of trees and shrubs

for noise reduction was an off-shoot of this project.

Trees and shrubs appeared to act as good noise-prevention screens, even though they could not

eliminate the noise completely. The green leaves actively absorb noise and its reduction may

also be due to the physical blocking of sound waves by the stem and the bark. Perhaps it was

because of this capacity that neem trees were traditionally planted in the front yards of

residences, tamarind trees on roadsides, and banyan trees in temples.​
