Part 4: What’s the difference concerning closed headsets and noise cancelling headsets?

That’s one of our most commonly asked inquiries, we get it much of the time and, frankly, we’re sick of sending the identical standard reply over and over again. So, we chose to resolve it once and for all.

Now, before we go to any extent further, I’m off to draft the stock email that directs you to this article, back in any minute…….You still here? Good. I stopped off to obtain a vitamin drink including a cup of tea as well, sorry.

OK. To state it plainly, there are two varieties of noise reduction, active and passive.

Passive noise cancellation/reduction is usually a by-product of wearing the headphones in the 1st place. If a headphone covers your ears up, it fundamentally has the same noise cancellation effect as a set of earmuffs. The sound has to work that much harder to travel to your ear if it must firstly go through a solid surface. Passive noise reduction arrives largely from blocking, or covering your ears and playing a louder sound in closer proximity. In case your friend is trying to speak with you and you can’t listen to them due to the headphones, then that’s passive noise cancellation.

Active noise cancellation/reduction is a bit more mechanical. Earphones that actively cancel external noise achieve this by producing a low field of white noise around your ear, this effectively masks outside noise is a purpose in and of itself, from the sound reproduction performance of the speakers.

To be truthful, anything you place in or about your ear carries a passive noise reduction effect, but only headphones pre-loaded with noise reducing functions will generate a masking white sound. This sound will not interfere with the working of your headphones, but it will cover the noise from wind, rain, road works and other train passengers and their noisy smart phone conversations.

Noise cancellation/reduction headsets will do a far better job of drowning out the noise pollution generated by barking dogs, train announcements, bad street buskers and those charity trolls who stop you in the street.

Joking aside, it’s much a frequently asked question because it is a good one to pose. Noise reduction functions significantly add to the cost of the headsets and it is absolutely worth knowing what you’re purchasing before you set your hard earned down onto the counter.
