# What Makes Sound Travel?

## 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..

## Will sound travel in a 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.

## What is sound caused by?

Sound is caused by the simple but rapid mechanical vibrations of various elastic bodies. These when moved or struck so as to vibrate, communicate the same kind of vibrations to the auditory nerve of the ear, and are then appreciated by the mind.

## Does the sun make sound?

The surface of the Sun produces sound waves because the surface is convecting and this produces pressure waves that travel into the inner corona. … But yes, the surface does produce sound waves, but they have very low wavelengths measures in hundreds of miles!

## What is sound short answer?

Sound is defined as vibrations that travel through the air or another medium as an audible mechanical wave. … around it to vibrate thus producing sound. Answered By. toppr. How satisfied are you with the answer?

## What are the 5 characteristics of sound?

Sound wave can be described by five characteristics: Wavelength, Amplitude, Time-Period, Frequency and Velocity or Speed.

## How fast do sound waves travel?

approximately 332 metres per secondThe speed of sound in air Sound can travel in air at approximately 332 metres per second. This is fast but not nearly as fast as light which travels at 300 000 kilometres per second. This difference in speeds enables us to appreciate that sound does take time to travel.

## Why is 194 dB the loudest sound possible?

Strictly speaking, the loudest possible sound in air, is 194 dB. The “loudness” of the sound is dictated by how large the amplitude of the waves is compared to ambient air pressure. … Essentially, at 194 dB, the waves are creating a complete vacuum between themselves.

## 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.

## 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.

## How does a sound wave travel through air?

Sound waves in air (and any fluid medium) are longitudinal waves because particles of the medium through which the sound is transported vibrate parallel to the direction that the sound wave moves. A vibrating string can create longitudinal waves as depicted in the animation below.

## What is the loudest sound in the universe?

The sound made by the Krakatoa volcanic eruption in 1883 was so loud it ruptured eardrums of people 40 miles away, travelled around the world four times, and was clearly heard 5,000 kilometers away. This is hailed as the loudest noise ever – and reported in.

## Why can sound not travel in space?

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.

## What makes a sound louder?

Changing the amplitude of a sound wave changes its loudness or intensity. … A string plucked with force has greater amplitude, and greater amplitude makes the sound louder when it reaches your ear. Volume depends on amplitude. Greater amplitude produces louder sounds.

## What frequency do humans vibrate at?

The important parts of the human body vibration frequency are generally located in about 3 Hz–17 Hz. According to the International Standard ISO 2631 in the vertical vibration of the human body, the sensitive range is located in 6 Hz–8 Hz.

## How does the sound travel?

Sound waves travel at 343 m/s through the air and faster through liquids and solids. The waves transfer energy from the source of the sound, e.g. a drum, to its surroundings. Your ear detects sound waves when vibrating air particles cause your ear drum to vibrate. The bigger the vibrations the louder the sound.

## Is Om the sound of universe?

The Om sound is the primordial sound and is called the Shabda-Brahman (Brahman as sound). In Hinduism, Om is one of the most important spiritual sounds. Om refers to Atman (soul, self within) and Brahman (ultimate reality, entirety of the universe, truth, divine, supreme spirit, cosmic principles, knowledge).

## Why is the sun so loud?

The answer might surprise you, as solar physicists estimate that the solar surface noise would be approximately 100dB by the time it reaches Earth! The enormity of the sun’s surface paired with its capability of generating of tens of thousands of watts of sound energy per meter makes the sun astronomically loud.

## What can sound not travel through?

vacuumSound cannot travel through a vacuum. A vacuum is an area without any air, like space. So sound cannot travel through space because there is no matter for the vibrations to work in.

## What is the loudest animal in the world?

## Why is Echo weaker than the original sound?

An echo is weaker than the original sound because it’s produced by a sound wave which travels through the air and then hits another surface, after…
