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.

∙ 15y agoI will answer your general question with a general answer. There is a direct coloration between the density of the medium and the speed of the sound (high density means faster speed of sound through it). If you want to increase volume in air, you need to direct the waves toward the desired point, sort of like a megaphone, speakers, etc. Keeping the sound from dispersing will make it "louder".

What would happen if a sound signal patterns pitch was increased but the volume stayed the same?
The sound would sound "higher" to you, but not any louder or softer.
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".
What happens when frequency is increased?
The cycles per second go up. If it's audible sound the pitch goes up.
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 is a sound that has a definite pitch?
A sound that has a definite pitch is a note.
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.

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 :)

What would happen to the sound produced by a stretched string if you increased it's tautness?
The pitch would increase, getting higher.
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.
What properties of sound determine the pitch of sound?
The pitch is determined by how high the sound is.
What property of sound determines the pitch of a sound?
It is the frequency of a sound that determines its pitch. The higher the frequency, the higher the pitch.
Pitch describes the loudness of a sound?
Pitch describes the frequency of a sound.
What is a sound that has a definite pitch?
A sound that has a definite pitch is a note.
