Can sounds travel through space?
Sound waves are travelling vibrations of particles in media such as air, water or metal.
So it stands to reason that they cannot travel through empty space, where there are no atoms or molecules to vibrate..
What is the loudest thing in the universe?
As far as I’m aware, the Perseus galaxy cluster is the current record holder for the loudest sound discovered in the Universe. Generating sound requires two conditions. First, there must be a medium that the sound waves can travel through, like air or some other gas.
How loud can a human yell?
Human screams can be quite loud, possibly exceeding 100 dB (as of March 2019, the world record is 129 dB!) —but you probably want to avoid that because screams that loud can hurt your ears! You should also have found sound levels drop off quickly as you get farther from the source.
Why is 194 dB the loudest sound possible?
The loudest a sustained sound can possibly be on Earth’s surface is 194 dB—which is when the amplitude of the sound wave is so intense that the low pressure part is a perfect vacuum (the wave alternates between double the normal atmospheric pressure and no air at all—not something you want to be present for).
Does higher dB mean louder?
The intensity of energy that these sound waves produce is measured in units called decibels (dB). The lowest hearing decibel level is 0 dB, which indicates nearly total silence and is the softest sound that the human ear can hear. Generally speaking, the louder the sound, the higher the decibel number.
Do sound waves travel forever?
Sound waves do not live forever. … As the energy of the sound is transferred to more and more molecules of air, they vibrate less and less until the effect is lost in the constant random jostle of air molecules. The sound is gone.
What if space had sound?
If space were replaced with air and we could hear the Sun, it would be incredibly noisy – the output of the Sun is equivalent to 10 million keys, or notes, of a piano. … Sound intensity decreases with distance, which means that the Sun would deliver a much smaller 125 decibels to the surface of our planet.
What would happen if sound would travel through vacuum?
Sound is nothing but waves and wave needs medium to pass through. … Originally Answered: What would happen when sound is forced into a vacuum? Sound requires air particles or molecules for the movement of vibrations produced by an object but there in no air inside a vacuum so nothing will happen.
Can you hear an explosion in space?
Sound needs a medium to travel (such as air), but space generally doesn’t have it. Therefore, sound can’t really propagate in space. So you can’t hear an explosion or any other sound in space.
Can sound kill you?
The general consensus is that a loud enough sound could cause an air embolism in your lungs, which then travels to your heart and kills you. Alternatively, your lungs might simply burst from the increased air pressure. … High-intensity ultrasonic sound (generally anything above 20KHz) can cause physical damage.
Can a sperm whale kill you with sound?
Sperm whales are so loud that their clicks are capable of killing a human within their vicinity, says one science and adventure journalist. … “These clicks are so powerful in the water that they can blow out your eardrums easily, and they can actually vibrate a human body to death,” he said.
What can sound not travel through?
We know light can travel through a vacuum because sunlight has to race through the vacuum of space to reach us on Earth. Sound, however, cannot travel through a vacuum: it always has to have something to travel through (known as a medium), such as air, water, glass, or metal.
