Quick Answer

Several characteristics define sound, including frequency, pitch, loudness, wavelength and period. Sound travels in waves and is caused by vibrations. Sound travels fastest through solids, slowest in gases and at an intermediate speed through liquids.

Full Answer

Bats and insects use a sound detection system known as echolocation to navigate their way through their environments. Echolocation is an example of a specialized sound detection system. During echolocation, a bat sends out high-frequency sound waves. An echo is returned and detected by the bat's auditory system. This method allows a bat to "see" in the dark, especially when it is looking for food.

  • Q:

    What determines the pitch of sound?

    A:

    Pitch is determined by the frequency of a wave, and frequency is the combination of wavelength and speed at which the wave is traveling. Sound has a constant speed of 343 meters per second, so wavelength dictates pitch. The longer a sound's wavelength, the lower the pitch of that sound.

  • Q:

    What does the frequency of a sound wave determine?

    A:

    The frequency of a sound wave determines what people hear as pitch. A higher frequency has a higher pitch, and a lower frequency is heard as a lower pitch. The frequencies that humans can hear range from 20 to 20,000 Hertz.
