Noise affects you as a professional, office worker, teacher, and student. It impairs your ability to read and write effectively, remember what you have learned, and do math. Everyday noise can cause a performance loss of 50 percent or more. This is easily the difference between an A and an F. Luckily there are some smart ways to block out and mask noise so it doesn’t disrupt you.
A good 18 months ago, I was sitting on my balcony watching an online lecture on my computer. My balcony is facing a small aisle, but the traffic noise from a nearby road is still very noticeable. I was wearing decent earbuds, so the noise wasn’t bothering me – or so I thought.
Just out of curiosity, I put on a pair of earmuffs, which I had purchased earlier to block out noises that often startle me during my early-afternoon naps.
Well, they did a hell of a job with the traffic noise: I was sitting there, and all the honking, squeaking and rumbling had receded into the background. It wasn’t completely quiet, but everything was so faint. That’s very nice indeed, I thought.
Why not try continuing the lecture with my earbuds underneath the earmuffs?
The first thing I noticed was that the voice of the lecturer was now way too loud. Annoyingly loud.
I had to turn down the volume from 10 to 3 to make it comfortable again. I also noticed that I could hear the finer nuances of the lecturer’s voice. I could even understand other students’ questions. These students weren’t equipped with microphones as this was a normal computer science lecture recorded at MIT in a big lecture hall (part of MIT’s Open Courseware program).
Wow – it was so much easier to follow the lecture and take in the whole experience. One of the great advantages of watching a recorded lecture is that you can stop it and re-listen to parts you couldn’t comprehend the first time. After putting on the earmuffs, this became almost completely unnecessary. Not only was I able to listen at a much lower volume and make out previously unheard details, I was also comprehending faster!
Bolstered by that experience, I experienced with earmuffs in other learning and reading situations as well
