How to block sound waves from coming through computer speakers?

I have a neighbor that talks on a ham/CB radio. He has about a 40ft antena and is able to talk to people states away. His broadcast comes through on my computer speakers. It used to come through one of our older TV's aswell. I have not found away to stop this, nor does the local electronic stores have a device that will stop this. I have been unsuccessful finding a device on line. Didnt know if anyone would have an idea.

Information on sound system for computer:
computer is not equiped with internal speakers. I have a surround sound style hook up. This was purchased from my computer manufacturer. All speakers are linked together. Three are your basic speakers for computer systems, one bass speaker and one high.

I was able to make it more tolerable by the speaker settings-I have manual volume control on the speakers very low, and the settings on the equilizer very high. This makes his broadcast lower in volume, and the sounds from the computer are higher in volume. TY
I thought of that, guy at the electronics store said that would not work-someone had tried that before, did not work because it was coming through by waves.

Also this condition is only active when the power to the speaker is on. If the speaker is off-no sound. That is why I thought of the filter before. But I took the guys word for it, base on his previous experience from other customers. TY
I have tried the metal shielding. No luck. I have not tried the wires. I have looked for alternate wiring, but with the system set up the way it is. Only the primary wire from the cpu to the first speaker is replaceable. I just havent taken the time to take apart everything and rewire it. Thanks for the answers.

flapjack said ¨report over modulation to the FCC. If you informed him of the issue and won't take care of it, they will.¨

What a stoopid bit of advice that is. ! ! !
It is MOST likely that the ham station is complying with ALL of the laws set out by the government.

Just because of the flood of NON compliant audio equipment (phones , tv's , sterio's and computer products) that is no reason to blame a nearby radio amateur for the interference.
In fact the radio amateur is not under any obligation to fix YOUR interference issue from poor equipment.

BUT -- fortunately most hams are good guys and if you go and see them and ask for interference reduction advice he is more than likely to help you out.

Older tv's were built to lower standards regarding strong signal rejection - so there may not be a lot that can be done with that.

Amplified computer speakers are often housed in plastic boxes and run unshielded (or poorly shielded) cable between the computer and the speakers.

This allows radio frequency energy to enter those parts and make the interference.
It is a problem with those parts and not the radio ham.
It can be helped by adding metal shielding inside the plastic speaker boxes and running new high quality cable from the amplified speakers to the sound card outlet.

Go ask the ham , he probably will like the challenge to fix your problem.

If he is a CB'er and has that sort of range he probably is running illegal power levels which is against the law.
Find out what and who he is first.

So - If he's a ham , work it out with him .. if he's a CB'er , probably call the FCC.

How can I Hook up an external subwoofer and still have my computer speakers playing?

Shawn Nutl

Just a regular computer speaker system minus the speakers, just the subwoofer. So the subwoofer plugs in and plays fine into the headphone jack and everything, but i would like to know how to play the subwoofer and my laptop speakers at the same time? I am using windows seven premium, and i am assuming i have to go to device manager and delete a file, but what file? or is it something completely different?!

Answer
Its something completely different

Its built into the sound driver to cut off your laptop speakers when you are using an external speaker system. You'd have to write a whole new driver.
