Question

We
we can hear a whooshing sound when we
hold a spiral conch shell near our ear, what
is the most likely reason behind this?​

Answer 1

Answer:

Sound waves whirl around in the conch shell and into your ear

Explanation:

If you look at your ear, it looks strikingly like a funnel! "But why," you say, "Why don't I hear any whooshing?" Well, your middle ear straightens the waves out so you can hear properly. The conch shell doesn't have a middle ear or a inner ear, so it sends extremely bent waves that your ear can't completely straighten out.

I hope this helped!

Answer 2

Reason is explained below -

• On placing a spiral shell near your ear, you hear the pleasent sound.
• The reason behind is shell acts as an amplifier and resonator of the sound waves that enter the shell.
• The incoming sound bounces inside the shell due to it's spiral structure, and hence it resonates the air inside the shell.
• Thus the sound heard is a whooshing sound.
