The shape of seashells just happens to make them great amplifiers of ambient noise. Any air that makes its way into a shell’s cavity gets bounced around by its hard, curved inner surfaces. The resonating air produces sound. The pitch of the sound depends on the size of the shell.
Is Whistlin Susie a real bomb?

Why do bombs whistle when they fall?
The change in the pitch of sound was due to the Doppler effect. When the bomb is dropped from the airplane, the velocity of the bomb goes on increasing due to gravity until it reaches its terminal velocity. As the bomb approaches towards the ground, the pitch increases and thus the “kooouuuueeee” sound.
Why did America nuke Japan?

The short answer: “shadowing out” of high frequencies and passive resonance. The detailed answer: The hands act as “low-pass” filters (they block out the higher frequencies). Almost everywhere has some form of background sound, but we tune it out. We notice changes in noise level and/or frequency.

Why does it sound like something is falling from the sky?
There are what astronomers call “electrophonic meteors.” Basically, the explanation is that these meteors give off very low frequency (VLF) radio waves, which travel at the speed of light. … The radio waves cause a sound, which our ears might interpret as the sizzle of a meteor shooting by.
Did US warn Japan of atomic bomb?
