If you hear a crackling noise coming from your speakers, you are listening to static interference. The problem is most commonly associated with computer speakers, but it can happen to any speaker. It is caused by a number of things, including magnetic interference and incorrectly installed cables. The static can be eliminated as long as you troubleshoot the problem and find the source of the static. Once you find the source, make the necessary adjustments and say goodbye to static once and for all.
Check the cable connections. Unplug each cable and wipe the jacks with a clean cloth. Dirty jacks may interfere with the connection between the cable and the speaker, which may cause static. Plug the cables in properly, so each jack is fully inserted into the ports. Check for breaks in the wires. If the wires are broken, purchase new ones.
Purchase shielded speakers. There are two types of speakers; shielded and unshielded. Speakers contain magnets which may interfere with electronic equipment, including computers. Shielded speakers prevent the magnet from interfering with other equipment. If you are using unshielded speakers, the magnet may be causing static interference.
Adjust the volume level of the speakers. When volume settings are at their maximum, distortion and static may be heard. Lower the volume of the speakers to reduce static.
Reinstall the driver for the computer's sound card if you are troubleshooting computer speakers. The static may be caused by computer or software error. Updating the driver from the computer manufacturer's website may fix the static issue.
