Speakers are meant to produce groovy and punchy sounds to the ears of the listeners. But when a speaker starts to give sudden bursts of random noise or crackle, it gets unpleasant and creates a problem for the listeners.
HOW TO FIX STATIC NOISE FROM SPEAKERS
Static noise is interference on a speaker commonly caused by atmospheric or environmental disturbances heard as crackles or loud hum in a speaker.
Static noise can easily ruin the listening experience of the listener, and the bursts can even cause damage to the speaker, by pushing them past their designated limits.
What can actually cause this static noise in the speakers? Well, the most common causes for any static noise coming out of the speakers goes thus;
DAMAGED WIRES AND OTHER PARTS
Damage wires are the most frequent cause of static sounds in speakers. When the wires that connect the speaker with the amplifier are cut or damaged, the speaker gets to produce static noise.
LOOSE SPEAKER WIRES
Speaker wires or cables are the most important part of the connection of any speaker. When the wires are loose, there would not be a firm connection to the amplifier thereby making the speaker produce static sounds or noise which needs to be get rid of.
OTHER POSSIBLE INTERFERENCE
Another possible cause of static sounds in the speaker is interference from the ground loop and other electrical devices. The ground loop basically creates a loud hum or buzz in the speaker which can affect the speaker when different devices are connected but powered by different AC outlets. For instance, plugging the amplifier into one AC outlet and the TV into another outlet. This can cause a ground loop hum in the speaker.
Static noise in the speaker can be fixed through the following options:
CHECK THE CABLES AND CONNECTORS
Make sure to check the connection of the wires thoroughly because loose or bad connections of wires are the major cause of the static and cracky noise in the speaker. There are RCA connectors, banana connectors, or bare speaker wires which are types and means of connecting the speaker to an amplifier or receiver.
For bare speakers, you can gently rotate or wiggle the speaker wires or cables used for connection while the audio is playing to see if they are loose or damaged to be sure about where exactly the static noise comes from. The speaker wires can become loose due to the frequent change of position of the speaker.
To fix it, remove the wires to ensure that enough of the wires are exposed beyond the shielding to maintain a solid connection. If the ends are gnarled, you can use a wire stripper to remove some inches of shielding in order to expose the wire more.
For the banana connectors, you can buy a new set of RCA audio cables to fit into the ports of the speaker properly in order to get rid of the static noise. The RCA cables should be firm in their appropriate speaker ports to avoid a bad connection bringing static noise.
Each solution depends solely on the type of speakers and connectors involved, just make sure that the connectors are vividly positioned and not loosen in the speaker’s ports and the amplifier.
CHECK THE CONE OF THE SPEAKER
A typical speaker is powered by a paper cone, a strong magnet that vibrates and creates sounds in the speaker. If there is a wear or tear in the cone, it can cause the speaker to produce a variety of static sounds, inconsistent humming, and constant hiss.
Remove the cover from the speaker and take a good look at the cone. If you have discovered a weary cone with a puncture and fallen ring, you should try and replace it with a similar cone or make your speaker go through a re-coned process by finding a bare speaker that is the same as the damaged one in size, wattage, and impedance to replace them.
You only need to remove the enclosure and cut the positive and negative wires running to the circuit board with the audio inputs and solder wires to the new speaker and then screw it in place. To avoid mistakes or cause more damage you can have your speaker repaired by a professional audio technician.
SEPARATE YOUR SPEAKERS AND AUDIO EQUIPMENT
Static sounds may also be caused by interference of speakers and audio devices. Electrical signals from other cables can easily cause a static sound when the speaker wires cross.
It is most common with speaker wire with a thin shielding. Proper cable management helps to get rid of potential sources of interference. Isolate the speakers and rearrange the cable so that they do not cross paths to cause interference.
If this option is not tenable for you due to the space or arrangement of your room, you can cover the speaker wires with a cable sleeve or better still hide them on the wall with an on-wall cable concealer.
To get rid of interference, you can also move away from your electrical devices like printers, mobile phones, and unnecessary devices from your speaker so as not to have an implication on the speaker.
CHECK IF THERE IS A GROUND LOOP
A ground loop that creates a loud hum or buzz in the speaker is another possible cause of interference giving a static sound. It is created when multiple devices are connected at the same time but powered by different AC outlets.
If this is the actual cause of the static sounds of your speaker, try to plug all your media and audio equipment into just a single surge protector power strip to get rid of the ground loop. If you do all these, the ground looping gets eliminated by keeping the ground from traveling through the other cables.
CHECK THE VOLUME SETTING
If the volume of the speaker is too high, it can cause static sounds or noise. Loud noise can freeze up the audio temporarily until it is returned to normal volume. In order to get rid of this static noise, you will have to lower the volume of the speaker a little bit to check for any changes possible.
Additionally, if your speaker is connected to a PC, you can check the speaker setting and fix it by following these simple steps:
Right-click the volume icon at the bottom right corner on your PC and select playback devices.
Also right-click your default speaker and choose “configure speakers”
Choose your audio channels as 5.1 Surround then click on Test.
When you see that the static sound keeps coming out from the speaker, you will now set your audio channels back to Stereo.
Generally, a good speaker wires for connections, audio equipment, and avoidance of any form of interference determines how well a speaker works to delivers good sounds without producing static noise.
