The wound wiring found in the speaker cord is very similar to the windings of an antenna. Very similar to electrical feedback, wireless systems can also interfere with sound systems. In fact, this type of feedback has been known to cause damage to the driver. Because the interfering signal is not related to the original sound source, the volume of the static noise is often independent of the system volume, meaning the noise you hear could be much louder than the intended sound. If a power cable is placed directly in line with or on top of a speaker wire, it could result in loud popping, crackling, and static. This energy is typically minuscule and is barely detectable, however, in certain conditions, these emissions could interfere with the signals being transmitted through sound system components and cable sets.

Power cords and power cables emit electromagnetic radiation at specific frequencies. However, outside influences can cause feedback that manifests as static in the speakers. In some cases, there is no problem with the sound system itself.
