Noise-cancelling technology is becoming increasingly popular, but what is it and what benefits does it bring to the professional environment?

What does noise-cancelling mean?

Noise-cancelling technology cancels out or reduces unwanted background noise.

When wearing a noise-cancelling headset, you will only hear the sounds that you want to hear from your earphones rather than background noise, which is often distracting. Similarly, a noise-cancelling microphone will filter out background noise and only deliver the desired vocal sound.

How does it work?noise-cancelling technology diagram

Active noise-cancelling technology erases lower-frequency sound waves by mimicking the sound wave, which causes both to cancel each other out. This is different to passive technology which reduces ambient noise by way of design, for example, ear cups that fit closely over the ear.

When do I need it?

Noise-cancelling technology was originally developed for aviation in order to cancel the noise in helicopter and aircraft cockpits. However, nowadays they’re available for everyday use, for example, for people working in call centres, or for hearing protection on construction sites. If your work environment can be noisy, choosing to use noise-cancelling headsets can increase productivity, as well as reducing the likelihood of suffering from hearing damage.

Benefits in the officeoffice benefits of noise-cancelling technology

There are several reasons why you should choose noise-cancelling technology for your work environment.

  1. It blocks out background noise without you needing to turn up the volume, so there is less of a chance of damage to your ear
  2. The immersive listening experience means better call quality, and therefore better customer satisfaction
  3. The “silence” you get with noise-cancelling headsets will help you focus and consequently you can be more productive

Types of noise-cancelling products


Noise-cancelling headsets block unwanted background noise. In order to get the most out of your noise-cancelling headsets, we recommend the binaural wearing style.


Noise-cancelling microphones are designed to filter out unwanted ambient noise from your speech. Almost always a noise-cancelling headset includes both a noise-cancelling microphone as well as earphones.

Hearing protection

In some industries, employees need heavy duty hearing protection in order to protect themselves from damage. Some headsets have built in hearing protection or helmets, so that not only is the user’s hearing and head protected, but they can also communicate using a two-way radio in challenging, noisy environments. If you need more information about buying heavy duty hearing protection to use alongside your telecommunication equipment, have a look at our buying Ear Defenders guide.
