Active Noise Cancelling

David Clark and many others are suitable for conversion to Active Noise Cancelling. This provides the pilot with a much improved listening enviroment. Engine noise is significantly reduced as is also listening fatigue that becomes apparent on long flights, damaging concentration.


The system works by the inclusion of a miniture microphone in each earcup. The signals from this microphone are fed to an amplifier circuit that then inverts the phase of the signal by 180 degrees. the two signals are then combined and the initially picked up background noise is thus cancelled out.

The cost of fitting the kit depends on the present specification of your headset. Gell ear seals are mandatory for best performance so if you already have a good pair you can save this expense. Also you can opt for a new cable that combines all signals and power in one feed, this is much tidier. Please call with details of your headset and we will explain all that is required and the costs involved. We never do any costly work without getting your permission first.

Cost of Noise Cancelling Upgrade

The cost of the ANR Upgrade varies depending on the current build of your headset. Also there are various options that improove the upgrade, for example you can opt for a combined Comm and Power cable that makes for a much tidier installation and is reccommended as it does not alter the appearance of the original build. 

A lot of headset's already have Gell ear seals so you may not need the addition of these, however they are mandatory for good ANR operation.

The average cost to upgrade with the Full kit on a standard David Clark  H10 13.4 that has gells is £315 including return postage.

You can save £50 if you fit the kit yourself and a further £25 if you do not have the combined comm cable.

If you are unsure please call me and i will explain the details for your individual requirement.
