Question

Birds avoid migrating to places where noise level is above ______.

Options

• 100 dB

• 90 dB

• 150 dB

• 140 dB

Answer 1

Birds avoid migrating to places where noise level is above 100 dB.

Explanation:

Birds avoid migrating to places where the noise level is above 100 dB because loud sounds interfere with their ability to communicate, navigate, and detect predators. High noise levels can cause stress and disrupt essential behaviors, such as mating calls or foraging. As a result, they tend to avoid areas with excessive noise to ensure their survival and proper migration.
