A shepherd's tone. It's an auditory illusion.
There's a video of how to make it happen at the related link below. Note: "Shepherd" was misspelled in the title of the link.
Sounds get higher in pitch as they get closer, due to the sounds waves getting packed closer together. (Which IS higher-pitched) Sounds get lower in pitch as they go away, due to the sound waves being pulled farther apart than normal. (Which IS lower-pitched). This is called the Doppler effect, and works with light, also.
Doppler effect.
because the pitch is higher
the different tautness helps make different sounds like a guitar. tighter strings = higher sound
The pitch would increase, getting higher.
Pitch- How high or low it sounds. The higher the pitch, the higher the frequency.Frequency- The number of wavelengths in an area. The shorter the wavelength, the higher the frequency.
Higher frequency, higher pitch.
It will it have a higher pitch.
the pitch; the smaller it is, the higher it sounds; the bigger it is, the lower it sounds
Pitch represents the perceived fundamental frequency of a sound. It is one of the three major auditory attributes of sounds along with loudness and timbre.
Pitch tone refers to the perceived frequency of a sound. It is how high or low a sound is perceived to be by the human ear. Sounds with higher frequencies are perceived as higher in pitch, while sounds with lower frequencies are perceived as lower in pitch.
