Sharing a problem that seems to be quite common with ANR headsets:
I can hear all the time a background white noise on the intercom.
The intensity of the background noise depends on the other pilot's headset type. (Sennheisers seem to cause the worst noise, don't know why!)
ps: boeing 738
Are you aware of any intercom "squelch" or "auto mute" portable accessory for the flight deck?
Something that would only allow me to listen to the intercom if the other pilot is actually talking!
I found this:
PS Engineering :intercoms
and this:
Pilot USA Portable 2-Station VOX Minicom - MyPilotStore.com
But I am not sure if they work and don't want to waste money!
Thanks in advance!
