Any electromagnetic wave in vacuum is about 881,000 times faster than any sound in air.
Ultrasonic means 'faster than sound'. This means no sound wave can be faster than sound.
A radio wave travels about 874,000 times as fast as a sound wave,plus it doesn't need any material to move through, as sound does.
The sound at 700 Hz vibrates faster, but both sounds travel from place to place through air at the same speed.
The speed is almost the same, for different frequencies.

The relationship between vibration and the frequency of a sound wave is that the frequency of a sound wave is directly related to the rate of vibration of the sound source. In other words, the higher the frequency of a sound wave, the faster the source of the sound is vibrating.
One can learn information about this year's Sound Wave event from: Wikipedia, Sound Wave, Festival, Faster Louder, The Music, Connected Events, Sound Wave Croatia, Sound Wave AZ, The Age, to name a few.
When a sound wave is absorbed, its sound energy is typically converted to heat energy. The vibrations of the sound wave cause the molecules of the absorbing material to increase in kinetic energy, resulting in a rise in temperature.
If the pitch of the sound increases, the frequency of the sound wave also increases. This means that the sound wave is oscillating at a faster rate, creating a higher pitch.
