The human sub-conscious is constantly ignoring sound that doesn't excite a reaction but that we are wholly surrounded by during daily routines. Driving is just one routine that is an example of this concept. If humans were to carefully listen to and identify all the sounds that surround us from all the different environments we encounter, our brains would become confused. Hence, we unnoticeably process through the sounds we hear and determine which ones we should listen out for as different sounds come with distinctive reactionary attachments. For example when we hear onomatopoeias' such as a 'pitter-patter' sound we have a memory reaction that reminds us that this sound means that it's raining. In 'Routine Sounds' a car horn and the radio can be heard. As purposefully designed, these are not the only loud and domineering sounds that can be heard in this recording from within the car. Although, these are two of the most common noises that humans hear within the car because they hold connections with particular emotional and physical reactions. The other noises are just as noticeable within the field recording, but without the attached reaction, in the everyday, we don't realise that they are there, they just are. In light of this statement, that we just assume that these noises will be there, these ignored sounds significance are heightened. If these noises were to completely disappear we would notice and begin to panic in the absence of normality. This highlights that although we ignore these sounds in the forefront of our minds, they are important in making sure our routine takes place as usual.
