Why are my Computer Speakers Humming?

Humming sound coming from speakers is a common problem that many people have to deal with. The hum of the computer speakers can happen for a variety of reasons. It is important to understand the cause of the humming before you take any action. Here we have listed the most important following reasons. This helps you to sort out the problem and fix it easily.

Improper Plugging of Speaker Cable

This is one of the common mistakes people do with their speakers. They don’t plug in the speaker cable to the PC properly.

The cable has rings and sleeves which act as a conductor and transfer the audio data from the source. If the cable is not inserted properly, you might hear the buzzing sound.

Sometimes, you can see that only one of the speakers is working properly. This is also due to improper plugging of the speaker cable into the input jack.

High Volume

Either by mistake or knowingly people may set the volume too high. When the volume is set very high, it will lead to excess sound pressure in the diaphragm. You can experience this even if you aren’t playing anything. The speaker keeps on humming without any file being played. 

This is due to the excess of electrical signals entering the speaker circuit due to the volume set being very high. Also, while playing with high volume, you might hear constant noise from the speaker.

Corrupt Audio File

When there are chances for the problem to reside in the speakers, it is also highly possible that the file you are playing might be corrupt.

A corrupt audio file may transfer corrupt digital signal which is then converted into electrical signals for the speaker to reproduce. This corrupt signal might be a humming or buzzing sound. Sometimes, it might even play the audio in bits and pieces. 

Damaged Sound Card

Hardware issue in the PC is also a major reason for the speakers to behave in such a manner. The sound card in the PC is responsible for transferring the audio signals to the external device connected to the computer system.

When there is an issue with the sound card, such humming and buzzing are very common. There are times when the sound card might be broken and may cause the issue.

Without a proper sound card, you will not be able to hear the desired audio from the PC. The improper signals transferred from the sound card may cause the humming.

Faulty Motherboard Circuit

The problem with the sound card may also arise due to circuit issues with the motherboard. Due to power surges or fluctuations, the motherboard might have some issues with the circuits and cause damage to the sound card.

There is a possibility where the sound card is good but the pins connecting them have some damages. You can easily remove the card and check the pins if you suspect an issue with the motherboard.

Damaged Speaker Hardware

The speakers have different electrical and mechanical parts inside them. Either there is an issue with the coil circuit or the moving parts in the speakers might have been damaged.

This type of damage will also cause humming. Especially if the speaker cones that are housed inside them are cracked or torn, the humming or buzzing is possible.

Frequency Interference

This is quite unusual but a potential cause for humming. If you have other electronic devices such as a mic or other heavy electricals in the proximity of the speaker, it may be the reason for humming.

Sometimes, when a high voltage cable is near the speaker cable, there might be a heavy interference that causes the humming. Microphones, Heavy Bass speakers near your normal PC speakers might affect its output and produce a humming sound.

Another major cause of this interference is the electrical ground loop. When you have connected too many or heavy devices in the same socket this usually happens.
