Large vibrations produce what kind of sounds?

Sound waves are mechanical waves that propagate through a medium (such as air) as a series of compressions and rarefactions (stretching) of the medium. This is also known as vibration. The distance between two corresponding parts of the wave, for example two compressions, is the wavelength. The number of compressions that pass by the same point in one second is the frequency, expressed by the unit Hertz (Hz) which is cycles per second. Since all sound waves travel at the same speed in a given substance, for example air at a constant temperature and pressure, the shorter the wavelength the more compressions that will pass by in a given time frame. This relationship is expressed mathematically as 

speed= wavelength x frequency

so wavelength and frequency are inversely proportional. 

The pitch that a sound wave produces depends on the wavelength and therefore frequency. Lower pitch is produced by longer wavelength and lower frequency.

So now to get to your question:

If by large vibrations you mean longer wavelength then the pitch of the sound produced will be lower. If by large vibrations you mean higher frequency then the pitch will be higher. The frequency of some vibrations is too low or too high to be within the range of human hearing.
