This section is divided into three parts. In the first part we shall take a look at how the human ear transforms sound waves into an electrical signal which is then interpreted by the brain. In the second part we'll be analysing how the brain perceives sounds. In this case it makes sense to use the word perceive in that the latter is infact a subjective interpretation by the hearing apparatus rather than the real nature of sound. To reinforce this point, the third part of this section shall reveal some of the mechanisms that modify sound perception when certain parameters are varied, like the position of the sound source in relation to the listener for example.
