When we refer to ‘noise’, we are talking about the hum of office equipment, chattering colleagues, traffic noise, ringing telephones, and notifications and meeting reminders from various apps.
WHAT IS NOISE CANCELLING?
Noise cancellation is a method for reducing these types of unwanted noise. There are two types of noise cancellation: active and passive. Passive noise cancellation consists of nothing more than an effective seal, such as that provided by ear plugs.
In contrast, active noise cancellation is much more advanced. Completely contrary to intuition, adding sound to the headset cancels disruptive background noise.
Noise cancelling technology is always located in the microphone of your headset. Therefore, it is very important you wear your headset correctly.
HOW DOES ACTIVE NOISE CANCELLING (ANC) WORK?
Sound consists of vibrating air that moves in waves. Headphones with ANC are fitted with a microphone that registers the environmental noise and technology that ‘reverses’ these sound waves. These reversed sound waves are then added to the sound emitted by the headphone’s speakers et voilà: the background noise is eliminated for the user.
HOW TO WEAR A HEADSET?
Fig. 1 Adjusting the headband and receivers
To adjust the headband, lengthen or shorten the band until it fits comfortably. The click-stop feature keeps the headband securely adjusted.
Position the headset receivers so that the foam cushions sit comfortably over the centre of your ears.
Fig. 2 On models with only one receiver
Position the stabiliser T-bar above your ear.
Fig. 3 Voice tube models
Hold the receiver securely against your ear with one hand. With the other hand, adjust the click-stop mounting and the voice tube so that the tip sits two finger-widths from the corner of your mouth. (To prevent breath noise, avoid putting the voice tube in front of your mouth).

If your noise-cancelling headset has a bendable boom. Carefully shape boom with both hands as shown. Do not bend or twist the boom within 50mm of the microphone.
Positioning the click-stop mounting and boom so that the microphone is two finger-widths from the corner of your mouth. Make sure that the front of the microphone faces your mouth. If necessary, carefully rotate the microphone into the proper position.
