Q:

How far can sound travel?

A:

The distance that sound can travel depends on what medium the sound wave has to go through. The speed of the wave affects the distance that it can travel. Temperature and atmospheric pressure also can directly affect the amount of distance a sound wave can cover.

Changes in materials, temperature and air pressure can speed up or slow down a traveling sound wave. The distance that a sound wave travels can be figured by multiplying the speed of the sound (approximately 345 meters per second under normal atmospheric conditions at a temperature of 20 degrees Celsius) by the time it takes for a person to hear it once the sound is initiated.

  • Q:

    How does sound travel?

    A:

    Sound travels through a medium as a mechanical wave. It cannot travel in a vacuum because it travels by vibrating the particles of the medium to transfer energy from one place to another.

  • Q:

    How does sound travel through a medium?

    A:

    Sound travels as a back-and-forth vibration of the particles of its medium. It is a longitudinal mechanical pressure wave that varies greatly in its speed of travel and the distance it remains coherent, dependent upon the medium. Sound in air travels relatively slowly and for a short distance, while sound in a solid, such as the primary waves of an earthquake, travel extremely quickly and to great distances.

  • Q:

    Can sound travel through a vacuum?

    A:

    Sound cannot travel through a vacuum, because sound requires a medium to form and travel. Despite what science fiction movies show, there is no sound in space.

  • Q:

    What are the characteristics of sound waves?

    A:

    The most basic characteristics of a sound wave are pitch, loudness and tone. A sound wave's frequency is experienced as the wave's pitch. The amplitude determines loudness or volume. The tone of a sound wave can be recognized by the regularity of its vibration.
