Have you ever noticed an odd sound emanating from the speakers while in your office? They could be buzzing, after all! Here are the causes and solutions. When the volume or bass is turned up too loud, speakers may buzz. Additionally, speakers might occasionally begin to sound distorted.
It can be annoying to listen to music if your speakers are constantly buzzing or producing static. Electrical ground loops can sometimes be the source of buzzing noises. Another potential reason for the buzzing is a blown speaker. The majority of the time, a blown speaker is actually a fairly small issue that you can easily resolve on your own without the need for professional assistance.
Let’s try to figure out why speakers buzz first.

Why are my speakers buzzing?
The issue with the speakers’ humming sound can have a variety of sources. The electrical ground loop is one of the frequently cited causes. You can’t ignore the audio output problems, even though frequency interference is also probably to blame for the buzzing sound problem. A hardware problem, such as a defective speaker, might also cause the buzzing sound coming from the speakers. Additionally, the problem is likely brought on by a software problem, like corrupt drivers.
Your speakers may be buzzing for a variety of reasons. The most frequent cause is when the bass or volume are pushed up too much, which puts a lot of strain on the speaker. Your speakers may begin to buzz as a result of a possible sound loop. The use of a subpar shielded audio connection between the speaker and the audio device may also contribute to this issue. Your speakers may buzz as a result of a potential ground loop that could result from this.
This issue could potentially arise if the extension cable you utilized was too lengthy or had bad wiring inside of it. The wire serves as an antenna for ambient noise, which may interfere with the sound card’s signal entering your computer or vice versa and cause a buzzing sound.
How to stop speakers from buzzing?
1. Troubleshoot the hardware
Prior to anything else, you should conduct this test first. Sometimes all it takes to stop your speakers from buzzing is lowering the volume. Sometimes you need to take a few more steps before the buzzing stops. We can begin troubleshooting by looking for any loose connections on the rear of your sound system’s input panel if detaching and reconnecting all of the speaker’s cords doesn’t seem to resolve the issue. If you’re using a laptop, these could be between the computer cable and the audio device, or between the audio equipment and its power cable, amplifier, etc.
After that, check to make sure no one has (unintentionally) changed any equalizer knobs that regulate the bass or treble levels while they were last in use. These modifications may have caused distortion and increased pressure in our speakers, which may have led to them buzzing.
2. Electrical ground loop
When two pathways share at least one place where current can flow, it creates an electrical ground loop; this includes extension cords used to expand the reach of laptops. Your speakers will buzz as a result of the audio ground loop isolator, and this is a persistent issue. If you believe this to be the issue, consider disconnecting and replugging any wires that seem flimsy, getting rid of all extension cords from your setup, or using a new cord for an audio device. You can also utilize an electrical ground loop breaker; these can be purchased on Amazon for a few dollars and are frequently found at hardware stores like Home Depot.
It might be beneficial for you to carry out this action while wearing headphones to listen to music. If the hum disappears when you use headphones but returns when you remove them, there is likely a grounding issue with the sound card or amplifier of our computer that is re-amplifying signal into itself through the power supply (and vice versa).
3. Change the cables
It’s crucial to remember that many speaker cables and cords are reasonably priced. These goods frequently have smaller wires, which can cause interference with the signal entering our computer through its sound card. This isn’t necessarily a hint that they’re badly manufactured (or vice versa). The best course of action is to switch to higher-quality audio cables, such as shielded or ferrite-braided HDMI or optical cables, AC cords, etc., if you notice that this is happening.
4. Avoid frequency interference
If you’ve done everything else and your speakers still seem to buzz, it’s possible that something is interfering with the frequency of our audio stream. This may be a more sophisticated troubleshooting step. The most frequent causes of interference are sound waves from power lines or a neighboring radio station, but there are many other potential sources of interference in a home, including WiFi signals, Bluetooth devices, telephones, and appliances like refrigerators or microwaves. This issue affects a lot of Bluetooth gadgets, including popular Apple AirPods and PC accessories.
If you’re unsure how outside noise affects your sound system, you’ll need to do some research. Try shutting off all electronics in your speakers’ space for a bit to see if that fixes the issue. If this is insufficient, it may be necessary to get in touch with an electrician who may offer assistance with more sophisticated grounding options.
5. Blown Speaker
Sometimes speakers will begin buzzing because they have been blown out; this can be brought on by a flaw, an overload on the speaker, or even just from playing music at high volumes for an extended period of time. If you believe that to be the case, it may be wise to get in touch with your neighborhood electronics shop and inquire as to whether they do repairs for your specific speaker type.
