Which of the following is NOT an effective way of reducing noise pollution in a city neighbourhood?
AIncreasing the volume of TV and music systems to mask outside noise
BPlanting trees along roads and around buildings
CConducting noisy operations away from residential areas
DInstalling silencing devices on industrial machines and home appliances
Answer & Solution
Correct answer: A. Increasing the volume of TV and music systems to mask outside noise
Raising indoor volume only ADDS to the overall noise and damages the listener's hearing. Effective measures attack the SOURCE: silencers, distance, and absorbing barriers (trees, walls) that dampen sound before it reaches people.
