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 electrical signals which are then interpreted by the brain. In the second part we'll be analysing how the brain perceives sounds. We will use the word "perceive" here since sound perception is a subjective interpretation by the hearing apparatus. To reinforce this point, the third part of this section shall reveal some of the mechanisms that modify sound perception when certain parameters change, such as for example the position of the sound source in relation to the listener.
