Indeed, the researchers found that face-to-face interactions and conversations affect the creative process, and yet a coworking space or a coffee shop provides a certain level of noise while also providing freedom from interruptions.

The differences between most of the groups were statistically insignificant; however, the participants in the 70 decibels group—those exposed to a level of noise similar to background chatter in a coffee shop—significantly outperformed the other groups.

The level of noise we hear also depends on the Angle and distance of the shell from the ear.
