I have begun my investigation into how our brain deals with sound in ways that dictate the information on what we need (What we hear) and what we dont need. The cocktail effect is a particular phenomenon that manifested my interest in this concept. The cocktail effect is the phenomenon that occurs when we are listening and absorbing information of one conversation in a room full of separate conversations at the same volume. Although, physically all the sound waves of these conversations are reaching our eardrums, or brain filters them out, so we here them as background noise, almost subconsciously quieter than the conversation that has our attention.
Another phenomenon that has begun to interest me is binaural beats. These are sound artifacts that induce a physical response and can improve brain function. Also when played in constant repetition they have the ability to subconsciously remove themselves from your auditory senses enabling you to concentrate on listening to something else. To experiment with this phenomenon i wrote the first half of this blog post with this binaural beat playing. I was able to compose and type the first paragraph in under 2 minutes. For this current paragraph i have been listing to this, a synthesizer producing randomly pitched notes. I have watched the five minute video twice and only got this far through the paragraph. What you can begin to conclude is that the ability to concentrate can be changed by what the auditory sense is engaging in.
