| Amplitude of Sound | Frequency of Sound |
| It is maximum displacement of a vibrating object from its central location | Number of Vibrations made in one second is called frequency of sound |
| It determines size of waves | It measures number of waves per second |
| It is measured in metre. | It is measured in Hertz |
| It measures how loud a sound is | It determines shrillness or pitch of sound |
| Higher the amplitude,more loud the sound | Higher the frequency, more shrill or high pitched is the sound |
