I get the classic "woodpecker" sound when I connect my noise-cancelling
headset to my phone. What can I do to kill that noise? Ferrite beads or
rings? Tinfoil around the electronics blob on the cable?
How do you connect the headphones to your telephone? Are the impedances
reasonably matched? Is thre any acoustic feedback from the headphones into
the microphone of the telephone?
I assume a mini-headphone jack plugged into the headphone outlet on the
phone is the right way to do it, and the impedance is probably
reasonably too. :-)
I am not talking about using the headset for "phoning", only for
listening to podcast/music while commuting publicly, so the microphone
on the telephone are not in business.
Sounds like a cell phone, and you're posting from a .dk domain
The problem is probably the rediculous pulses GSM phones send out.
This not a problem with the properly designed CDMA system.
Is this the sound you're hearing?
