Can a poorly made electrical cable cause noise?
As to the quality of cables: A poorly made cable can cause noise issues, but there’s no real advantage to spending a fortune on them. A common misconception is that the more expensive the metal, the better the cable. Wrong. Gold is used on connectors because it doesn’t oxidize, not because it’s the best conductor of electricity.
What kind of interference is caused by noise?
Few words about interference… Noise, or interference, can be defined as undesirable electrical signals, which distort or interfere with an original (or desired) signal. Noise could be transient (temporary) or constant. Unpredictable transient noise is caused, for example, by lightning.
Why is there noise in my audio system?
Other systems such as air conditioning, navigation systems, lights, turn signals, cell phones, and other components can cause noise in the audio system. If any of these is causing the noise, you may need to reroute the wires in the back of the receiver to move them away from the source of the noise.
What causes interference in a loudspeaker amplifier?
Usually it’s the electronic engineering of the amplifier that is responsible for causing loudspeaker interference. When the hissing is so loud that it effects the listening experience then something’s has to be done.

What should I do if my audio system is making a low hiss?
If you have an external amplifier in your system, the first thing to do is to quiet any system noise, which sounds like a constant, low hiss. First, check for system noise with the engine off. Insert a CD and put your CD player on pause. Listen to the system with the volume way down, then way up.
What should I do if I hear a hissing sound from my amplifier?
If you hear a hissing sound, turn down the gain on the amplifier and turn up the volume on the receiver. Adjust these two settings to minimize the hiss. Make sure the patch cables between the amplifier and the receiver are not running near other power wires (including the wire providing power to the amplifier).
Can a hearing aid completely eliminate background noise?
Although hearing aids may not completely eliminate background noise, they do have very sophisticated noise processing circuitry, which means the sound quality is more natural, even with background noise present.
