As you know, we are not equally sensitive to sounds of all frequencies so perceived loudness of a tone in fact depends on frequency as well as intensity. Two sounds can have the same physical sound pressure levels but if they are of different frequencies, they are often perceived as having different loudness.

Loudness of sound is proportional to the square of the amplitude of the vibration producing the sound. For example, if the amplitude becomes twice, the loudness increases by a factor of 4. The loudness is expressed in a unit called decibel (dB).

amplitude

Besides the pitch of a musical note, perhaps the most noticeable feature in how loud the note is. The loudness of a sound wave is determined from its amplitude. While loudness is only associated with sound waves, all types of waves have an amplitude. The farther away the smaller the amplitude.

Difference between Pitch and Loudness The pitch of a sound is our ear’s response to the frequency of sound. Whereas loudness depends on the energy of the wave. The pitch of a sound depends on the frequency while loudness of a sound depends on the amplitude of sound waves.

Shrillness is a word used to describe the quality of sounds that have a high-pitched, strident, raucous, screeching or harsh character, such as those produced by a trumpet or piccolo, but it can also be used to describe a widely recognised and puzzling phenomenon whereby certain sounds are perceived as psychologically …

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

First, let’s think about why sound does not travel forever. Sound cannot travel through empty space; it is carried by vibrations in a material, or medium (like air, steel, water, wood, etc). So, the sound wave gets smaller and smaller until it disappears

Sound travels at one of the fastest rates through aluminum, at 6,320 meters per second

In fact, sound waves travel over 17 times faster through steel than through air. Sound waves travel over four times faster in water than it would in air

Sound waves travel faster in denser substances because neighboring particles will more easily bump into one another. Take water, for example. There are about 800 times more particles in a bottle of water than there are in the same bottle filled with air. Thus sound waves travel much faster in water than they do in air

Sound waves actually travel five times faster in water than in air. Underwater those sound waves don’t vibrate the ossicles bones in your inner ear. They go straight to the skull bones, vibrating that heavy bone you can touch just behind your ear. Because of that, you can hear higher frequencies underwater

If a caller sounds like they are underwater, the network is likely unable to supply enough Internet speed, or there is faulty networking equipment or a loose connection. Common symptoms of muffled audio include: Inbound audio sounds muffled or like the caller is in a tunnel. Inbound or outbound audio cuts out.

There is no atmosphere on the surface of the Moon. Sound cannot travel without a medium. Hence, there is no sound on the Moon.

Therefore, the fart will not be smelled by the astronaut, although they may marinate in it for a time. 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

No, space is a virtual vacuum. The only way you could hear yourself scream in space is if you were in a spacesuit with an available oxygen supply since sound waves require a medium to travel through. You’d feel your vocal chords vibrating though.

Spaceflight influences biology in dramatic ways, and people in space appear to experience the effects of aging faster than people on Earth. The health effects associated with spaceflight have several similarities to aging-related disorders, such as cancer and osteoporosis

Sound is a mecanical wave, which means that it needs substance to travel through, such as air or water. In space, there is no air, so sound has nothing to travel through. If someone were to scream in space, the sound wouldn’t even leave their mouths

If you do die in space, your body will not decompose in the normal way, since there is no oxygen. If you were near a source of heat, your body would mummify; if you were not, it would freeze. If your body was sealed in a space suit, it would decompose, but only for as long as the oxygen lasted
