Relative motion does it. If an observer (listener) and a source of sound are moving toward or away from each other, Doppler effect will kick in. That's where any wave appears higher in frequency as distance between observer and source shrinks, or lower in frequency as that distance expands. There are numerous video "enactments" of the effect on YouTube and in other locations. A brief clip of a locomotive coming at the camera, passing it and then retreating down the track demonstrates Doppler effect. A clip of an F1 car approaching, passing and disappearing down the straight on a race course may be even more dramatic. The pitch of the sound is higher on approach, "levels out" as the source passes, and then decreases in pitch as the source moves away. It may be possible to alter the source of the sound to get an increase in pitch. But this may not be "simple" as asked, depending on the source.
What else can I help you with?
What will be the effect on wave length of a sound if the pitch of sound is increased?
If the pitch of a sound is increased, the frequency of the sound waves also increases. Since the speed of sound remains constant in a given medium, an increase in frequency results in a decrease in wavelength. Thus, a higher pitch corresponds to a shorter wavelength.
What would happen if a sound signal patterns pitch was increased but the volume stayed the same?
Increasing the pitch of a sound signal without changing the volume would result in a higher frequency of the sound waves. The sound would be perceived as higher in pitch, but the overall loudness would remain consistent. This change in pitch would not affect the perceived volume of the sound.
How does pitch affect sound?
A high pitch (> 2 kHz) of a pure tone will be perceived to be getting higher if its loudness is increased, whereas a low pitch (< 2 kHz) will be perceived to be going lower with increased loudness. Sometimes called "Stevens's rule" after an early investigator, this psychoacoustic effect has been extensively investigated Scroll down to related links and look at "Effect of Loudness Changes on Perceived Pitch".
Why pitch of sound increased when a person inhale helium?
It displaces oxygen/air in your lungs because H is heavier then oxygen/air. Therefore changing the characteristics in how you sound.
What happens when frequency is increased?
When frequency is increased, the number of complete wave cycles that pass a point in a given time increases. This results in a shorter wavelength and higher energy for electromagnetic waves. In terms of sound, higher frequency corresponds to higher pitch.
What happens to the pitch of a note when the frequency is increased?
If the frequency of a sound is increased, the pitch goes higher.

What happens to a sound if the frequency is increased?
If the frequency of a sound wave is increased, the pitch of the sound also increases, making it sound higher. This means that the number of complete cycles of the wave occurring in a second is increased.
What happens to the eardrum if the pitch is increased?
When the pitch is increased, the frequency of sound waves also increases, causing the eardrum to vibrate at a higher rate. This increased vibration can lead to increased pressure on the eardrum, potentially causing discomfort or even damage if the sound level is too high.

Increasing the pitch of a sound signal without changing the volume would result in a higher frequency of the sound waves. The sound would be perceived as higher in pitch, but the overall loudness would remain consistent. This change in pitch would not affect the perceived volume of the sound.

What would happen to the sound produced by a stretched string if you increased it's tautness?
The pitch would increase, getting higher.
Why does inhaling helium increase voice pitch?
Because Helium is lighter than air so when you breath it it makes your vocal chords move faster giving you an increased voice pitch
For a stationary observer when the source of a sound is moving its?
When the source of a sound is moving towards a stationary observer, the pitch of the sound will appear higher (increased frequency). When the source is moving away from the observer, the pitch will appear lower (decreased frequency). This phenomenon is known as the Doppler effect.
The pitch of the sound is increased. What difference will this make to the way the ear drum vibrates?
it does not do any thing :)
Why pitch of sound increased when a person inhale helium?
It displaces oxygen/air in your lungs because H is heavier then oxygen/air. Therefore changing the characteristics in how you sound.
How are frequency and sound related?
The frequency of a sound wave affects the pitch of a sound. A higher frequency sound wave produces a higher pitch sound. On a piano, the pitch A4 (A above "middle C") will produce a soundwave with a frequency of 440 Hz. The pitch A3 (A an octave below A4) will have a frequency of 220 Hz. The frequency of A5 (A an octave above A4) is 880Hz. "Midde C," or C4, has a frequency of approximately 262 Hz.
