sound, n.Trivia

A whip must be travelling faster than the speed of sound at the tip in order to crack. It is literally a tiny sonic boom

Submarine sonar is no a “ping” like movies and games, but actually extremely loud and can kill people and sea life

Sound is able to travel 15 times faster through steel than air

Sound travels quicker through solids owing to the fact that molecules in a solid medium are much closer together

Blue whales are able to produce the loudest sound of any animal. At 188 decibels, the noise can be detected over 800 kilometers away

The intensity of sound is measured in decibels (dB), the decibel scale is logarithmic. Basically a 40dB sound is not twice as loud as 20dB, but a 100 times louder. Also 1 alarm clock ringing at 70dB, 2 alarm clocks ringing together don’t hit 140dB on scale but measure 73dB.

Sound is able to travels 4.3 times faster through water than in air

The loudest sound in recorded history was the Krakatoa volcanic eruption in 1883. The sound was so loud that it ruptured the ear drums of people 40 miles away, traveled around the world 4 times, and was clearly heard 3,000 miles away

Space is completely silent

Elephants communicate in sound waves below the frequency that humans can hear

Fresh snow absorbs sound, lowering ambient noise over a landscape because the trapped air between snowflakes attenuate vibration.

Pistol shrimp can make a noise loud enough to break glass.

If sound could travel through empty space, the sun would be louder than a train horn about one meter away (125 decibels)

Sound is able to travel up to 15 times faster through steel than air, at speeds up to 19,000 feet per second

Cats are able to hear ultrasound

Sound is able to travel quicker in water than in air

Sound is able to travels 10 times faster through granite than air
