Ultrasonic sounds
If the high frequency sound is within hearing range, you can hear it as a high-pitched sound. If it's out of the hearing range you can't hear it, of course.
Within the normal range of hearing, the higher the frequency (number of vibrations per second) the higher the perceived pitch. Frequency is a physical characteristic and pitch is a psychological characteristic.
The ability to perceive sound varies with pitch in that higher pitch sounds have higher frequencies, which can be more difficult to detect than lower pitch sounds with lower frequencies. Our ability to perceive sound also depends on factors like age, hearing health, and environmental noise levels. Generally, human ears are most sensitive to sounds in the frequency range of 2,000-5,000 Hz.
Sound waves with frequencies above the normal human range of hearing are called ultrasoundUltrasoundUltrasonic for frequencies higher than a human can hear, and infrasonic for those frequencies below the human threshold of hearing.

It is the frequency of a sound that determines its pitch. The higher the frequency, the higher the pitch.
I am very sorry to tell you that it just makes the sounds louder. It would take a lot of technology to make it a higher pitch. I even tried it by myself and it didn't work.
They vibrate over a wide range of rates. The faster the vibrations, the higher the pitch of the sound.
What we consider a "high pitched frequency" is the upper end of our normal hearing range. The normal hearing range of human beings is roughly 10 hertz to 25,000 hertz. Sound is transmitted from point to point by series of compressions of air. The number of these compression packs in any given second is a hertz (also referred to as cycles per second). Low frequencies (pitches) take more power to produce compared to higher frequencies. An interesting phenomenon in humans is that as we age we lose the ability to sense the upper range of our hearing. There are now phone ring tones that only young people can hear, because us old folks have lost the ability to hear the sound.
There are two parameters regarding hearing ranges. One is frequency range, and the range of hearing is measured in Hertz, which is cycles per second. Another variable is the threshold of hearing. In other words, how loud does a sound at a given frequency have to be to be heard. That sound level is measured in decibels with respect to a reference level. The threshold level will vary with the pitch (frequency) of the sound, as you might have guessed.
The one with highest frequency. The limit of human hearing is 20khz. Sounds can be made at much higher frequencies.
Whenever there's something vibrating, in the upper range of human hearing, there may be a high pitch sound.
