How far away can sound travel?

How far away can sound travel?

As you can see, the speed of sound changes depending on the temperature and the humidity; but if you want a round number, then something like 350 meters per second and 1,200 feet per second are reasonable numbers to use. So sound travels 1 kilometer in roughly 3 seconds and 1 mile in roughly 5 seconds.

How far does sound travel in a year?

Since the speed of sound at the Earth’s surface is 331 m/s and there are 31.558 million seconds in a year, one would, in principle, travel nearly 10.5 million kilometres, or 260 times round the Earth.

Is there sound on the moon?

No, you cannot hear any sounds in near-empty regions of space. Sound travels through the vibration of atoms and molecules in a medium (such as air or water). In space, where there is no air, sound has no way to travel.

Is sound louder in water?

Sound travels faster in water compared with air because water particles are packed in more densely. Thus, the energy the sound waves carry is transported faster. This should make the sound appear louder.

Can sound waves travel in vacuum?

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.

Can you see a fart in space?

When astronauts are not in the space suit and floating about, the fart smell is exaggerated by the lack of airflow from the recycled air used and its inability to mask any smell. As per your second question on the ability to thrust about in space from a fart, this is very near impossible.

Why can’t we hear any sound on the Moon?

The air here on Earth allows sound waves to move from one point to another (sound can also move through water, steel, earth, etc… it just requires that particles/atoms/molecules are touching one another). Thus there is no sound on the Moon.

What is the loudest noise in the world?

The loudest sound in recorded history came from the volcanic eruption on the Indonesian island Krakatoa at 10.02 a.m. on August 27, 1883. The explosion caused two thirds of the island to collapse and formed tsunami waves as high as 46 m (151 ft) rocking ships as far away as South Africa.

Can humans hear underwater?

Sound that’s generated underwater stays underwater; very little sound passes from water to air. When your head is out of the water and you listen to a sound made underwater, you don’t hear much. But when you’re under water, the sound travels so fast that it reaches both ears at almost the same time.

Why does sound not travel in vacuum?

Sound does not travel at all in space. The vacuum of outer space has essentially zero air. Because sound is just vibrating air, space has no air to vibrate and therefore no sound. Radio is a form of electromagnetic radiation just like light and can therefore travel through the vacuum of space just fine.

Why it is that sound Cannot travel in vacuum?

Sound is formed by the vibration of the particles in the medium like air, water etc through which the waves travel. Therefore sound cannot travel through vacuum where there is no molecule or atom to induce vibrations.

What determines how far a sound will travel?

Water temperature and pressure determine how far sound travels in the ocean. While sound moves at a much faster speed in the water than in air, the distance that sound waves travel is primarily dependent upon ocean temperature and pressure.

How fast can sound travel?

We know that sound travels. How fast does it travel? Sound travels about 1500 meters per second in seawater. That’s approximately 15 football fields end-to-end in one second. Sound travels much more slowly in air, at about 340 meters per second , only 3 football fields a second. Jan 28 2019

How many feet do sound waves travel per second?

Sound travels through air at ” the speed of sound .” Officially, the speed of sound is 331.3 meters per second (1,087 feet per second) in dry air at 0 degrees Celsius (32 degrees Fahrenheit). At a temperature like 28 degrees C (82 degrees F), the speed is 346 meters per second.

How far does sound wave travel in miles?

The speed of sound is the distance travelled per unit of time by a sound wave as it propagates through an elastic medium. At 20 °C (68 °F), the speed of sound in air is about 343 metres per second (1,235 km/h; 1,125 ft/s; 767 mph; 667 kn), or a kilometre in 2.9 s or a mile in 4.7 s.
