What determines the frequency and amplitude of the sound produced by a vibrating object? i need to write this as a hypothesis.

At the point when a substance vibrates, it produces sound. The greater the vibrations, the more amplitude and the louder the sound.  

Sound waves can be broke down regarding their amplitude and frequency. The loudness of a sound compares to the amplitude of the wave and is estimated in decibels. The frequency of a sound wave influences the pitch of the sound we hear. Most melodic sounds are made out of a superposition of numerous frequencies called partial tones, or essentially partials.

it is a negative acceleration
