#HearingFactFriday: The momma bear of noise levels is 70 dB

Looking for trivia grist for your Zoom ice-breaker, group text thread, or family dinner conversation? Our Hearing Fact Fridays never disappoint.


In a 2017 Harvard Business Review article titled, “Why you can focus in a coffee shop but not in your open office,” author David Burkas referred to a study that examined how various background noise levels impact people’s creativity.


The randomized study exposed groups of participants to background noise ranging from total silence, to 50, 70 and 85 decibels (the level where hearing loss can start).


Interestingly, the difference between all levels was “statistically insignificant,” except for the 70 dB level, which is similar to the background noise level in a coffee shop. Participants in that group “significantly outperformed the other groups” while taking a Remote Associates Test, a test that judges creative thinking.


The study, and Burkas, conclude that optimal creative thinking happens with a right level of noise: not too loud, but not in total silence either. And 70 dB seems to be just right.


Not sure how loud your surroundings are? Our free SoundCheck app lets you check the decibel level of any environment you're in.
