Lastly, the right amount of background noise, not too quiet and not too loud, can also help you to think in a more abstract way enhancing creative thinking. Music tends to be more rhythmic and unpredictable and if it contains lyrics, it will easily mess with your concentration and shift your focus to the lyrics instead of the task at hand. This is also why music with lyrics can bring us easily out of focus, especially when having to deal with tasks that involve writing or reading. Therefore, additional noises are blended in and you don’t perceive them as disturbing as you normally would. Noisli is a free website that offers relaxing sound clips to help listeners be more productive, relax, or reduce stress. While listening to such background sounds, every additional noise adds to the sounds you’re already hearing and doesn’t stand out so much anymore. Moreover, due to the high amount of different frequencies contained, background sounds have great masking abilities, reducing the negative impact of sudden spikes in external noise in our environment. Background noise on the other hand is a sound that doesn’t contain spikes in volume, that is very constant and rather predictable keeping therefore our inner alarm systems calm. It is the opposite of what we need when we want to focus or relax.

Silence and loud noises are usually associated with danger, thus making us alert.
