Question

Sound is heard more clear at night. Why?

Answer 1

Explanation:

because at the night there is no noise of machine and other so noise cannot collide by each noise other so we can hear sound more clearly at night

Answer 2

The transmission of sound in night is clear than the day time.

• It is because of the fact that propagation of the sound in air in day time due to the hotter weather, there will be multiple refraction of sound.
• As the multiple refraction of sound this cause decrease in the hearing
• But during the night, it is bit cold so there will be not so much refraction of sound and that leads to the more clear hearing of sound
