~Music has a pleasing effect on mind and ears. Noise, on the other hand appears to be pretty irritating and is basically a nuisance.

~Music usually has a high frequency. It also exhibits a recognizable pattern of changes in amplitude as well as wavelength. Noise, on the other hand exhibits lower frequency, irregular wavelengths and also produces sudden changes in wavelength and amplitudes.

~Music is actually a combination of harmonics and frequencies. Noise on the other hand, has no such properties.

~Noise is considered “chaos” and music is harmony.

~Music is very soothing to listen to while noise is wild as well as untamed.

~Music can be considered to be some form of organized noise, a special category of noise. On the other hand, it can be said that noise is basically nothing but sounds in random having no order or rhythm.
