Noise Feedback in car.

I plug set it up in my car, plays fine except I can here feedback noise. Kind of a high pitched noise that changes with RPM.
Troubleshooting:
1. The noise is still there if I unplug the antenna with the unit on. (excludes the antenna)
2. The noise stops if I turn the unit off (excludes my amp)
3. The noise is not there if I use another source such as my iPod with the same cord into the aux input.
ideas?

I had the same problem. I tried everything. I got a ground loop isolator that goes from you stereo to your satelite. Works like a charm! You can get one at radio shack for 16$.

Your picking up electronic engine noise. Is this an older car or new car? If it's an older car it may just need servicing. Due you have electronic fuel injection? When was the last time your plug wires or your rotor and cap been replaced?

Here is a simple test when it's pitch dark out. Open your hood and start up the engine. Look for electrical sparks or blue colored electrical current near and around any spark plug wires.

Do not touch the wires or it will knock you on your ***!

Cassette deck high pitched noise when playing


Sometimes this is caused by the record circuit being activated due to some kind of faulty switch. At other times it's caused by a fault on the pre-amp circuit. Possibly in the power supply to it. Perhaps a faulty capacitor?

Loud high pitch feedback when audio plays


I can only think of tree possibilities:


1. Feedback created by a dry join on a circuit board
2. Feedback from a cooling fan that has malfunctioned
3. Feedback from a microphone that has malfunctioned

I would try disabling or fiddling with the settings on the microphone first, if that's the problem, I recommend you disable it and if you use a microphone regularly, the external alternative is quite a cheap way of replacing it, if its a cooling fan, and you have the knowledge to disassemble the laptop, try disconnecting it for a short time, if the feedback stops when you disconnect the fan, you need only replace the fan, if these two methods don't solve the problem, I would recommend you have a professional look at it for you, dry joins are quite hard to find and require special equipment to fix, and if that's not the issue, the professional should be able to find the problem anyway.

Good luck

High pitched noise in speaker


Could be an alternator problem. Bad ground wire or just old bad wiring.
If you have an amp then the power wire is to close to the speaker wire.

Hi, when I press the left eatcup close to my ear, there is this very loud high pitch noise that comes from it and is unbareable. I have to removed them inmediately. What can I do, and what those this...


The design of these headphones includes a microphone on the outside and on the inside of each earcup. The outside microphone detects outside noise. The inside microphone monitors what you are hearing and when it detects that the outside noise is present inside, the active noise-canceling circuits remove that noise. This happens fast enough that you perceive a siginficant reduction in the outside noise getting to your ears.

The airspace inside the earcup is a tuned chamber defined by the foam in the ear cushion. This is important because with the inside microphone in close proximity, but at a 90-degree angle to the speaker, the circuit must be designed to eliminate the normal feedback that occurs. When you press the earcup close to your ear, you are changing the size and shape of the air chamber inside of the earcup thus directing more of the speaker sound toward the microphone than the design can compensate for causing audio feedback to occur. You are hearing that feedback. Removing your hand from the earcup should restore the shape of the air chamber allowing the circuits to return to normal operation.

If the feedback occurs too easily when you are NOT pressing on the earcup, then the foam may have weakened/deteriorated and it may be time to replace the ear cushion.

On my QC-3 headphones, I can cause the feedback squeal in both earcups, with the left earcup being more sensitive to the shape change than the right.

Feedback noise when overdrive is on


it could be your guitar pickups. try using another guitar or getting your pickups waxed at your local music store. also if your playing in a small room kind of loud, or if your using single coil pickups (like fender statocaster pickups) you will definitely get a feedback noise. if that does not work let me know.
