All sources of noise are natural. Noise is otherwise defined as soundwaves, which vibrate through matter until they reach your eardrums and the energy used to cause the vibrations is translated into noise by your brain -the pitch is determined by the frequency of the vibrations-. Anyway, it does not matter how the soundwaves are created, it is all natural. You cannot create synthetic noises as far as the physics are concerned.

The difference between natural and artificial sources of light is that natural sources are produced by the sun while artificial light sources illuminate using energy from other sources and include incandescent bulbs.

The word 'Noise' in communication theory is a barrier to communication that may weaken or destroy a message that is trying to be relayed There are a number of ways to classify noise. It can be subdivided according to type, source, effect, or relation to the receiver, depending on circumstances. In order to make the classification more compact, noise sources can be divided into two main groups: • Noise whose sources are external to the receiver (External Noise) and • Noise source created within the receiver itself (Internal Noise). types include: Shot noise; Johnson noise; Partition noise and White noise
