Phone noise in noise canceling headphone

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.

If I do, will the phone still make the noise when trying to connect to
a carrier on another continent? I'm in Denmark. Europe, you know :)

I am not familiar with the "classic woodpecker" sound, can you please describe it?
I am assuming that if you just listen to the music on the telephone instrument you do not get any noise?? When you are listening just on the telephone, is it live - being downloaded as you listen, or is it music that you have previously downloaded to the telephone?

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?

You are right. I can on my phone select
* GSM/WCDMA (automatically)
* GSM only
* WCDMA only

I'll try WCDMA only next time.

It is the GSM noise cydrome references:

I do not get the noise when listening on the cellphobes speakers (But
my fellow commuters would probably complain).

I only gets the noise on the headphones when the active noise-canceling
electronics is turned on, not when it is turned off and it is working
like a regular headset.

I get that noise over CDs I rip onto iTunes on my MacBook Pro. It comes and goes as the recording is progressing. It is incredibly annoying when you record 20-30 CDs and then have to listen IN REAL TIME to all of them to see which are affected to re-record them and hope the clicking doesn't recur!

It should be possible to design a noise detection system similar to the SAE impulse noise reduction system which recognises scratches on LPs but a better way should be to figure out which bit of the computer needs better shielding. I don't get the noise when I record the CD with the phone AWAY from the computer, eg charging in another room.

(sorry if this is a bit OT: I have a half dozen pairs of noise reduction cans and have never had this problem with any of them)

As every Part 15 advisory on every thing with an oscillator in it says,
if problems are encountered increase the distance between the devices.
