How to fix a buzzing speaker

Have you been sitting in your office and heard a strange noise coming from the speakers? It could be that they are buzzing! Here’s why and how to fix them. Speakers might buzz when the volume or bass is turned up too high. Sometimes speakers will also start to sound distorted. Nevertheless, let’s first try to understand why speakers buzz.

But why are my speakers buzzing?

There are multiple reasons why your speakers could be buzzing. The most common reason is when the volume or bass has been turned up too high and it’s putting a lot of pressure on the speaker. This can cause a sound loop to form, which will make your speakers buzz.

This problem might also happen if you’ve used an audio cable with low-quality shielding in between the speaker and the audio device. This can cause a ground loop to form, which will make your speakers buzz.

This problem might also happen if you’ve used an extension cable that is longer than necessary or has faulty wiring inside of it. The wire acts as an antenna for outside noise – this can lead to interference with the signal going into your computer from your sound card (or vice versa) and create a buzzing sound!

What do I do now?

If you think any of these problems may be happening in your sound system then there are a few things you should try doing before reaching out to customer service.

1. Troubleshoot by checking the speakers, knobs, cables, etc.

This is the first thing you should do be testing before anything else. Sometimes it’s just as simple as turning the volume down and your speakers will stop buzzing. Other times you may need to go through a few more steps before it stops buzzing.

If disconnecting and connecting all cables from the speaker doesn’t seem to solve the problem then we can start troubleshooting by checking if there are any loose connections on the back of your sound system’s input panel. These could be between either your computer cable (if you’re using a laptop) or the audio device’s connection with its other devices like power cord, amp, etc…

After this make sure no one has (accidentally) adjusted any equalizer knobs that control bass levels or trebles since the last time they were used – these adjustments might have caused distortion and increased pressure in our speakers which could have caused them to start buzzing.

2. You might have an electrical ground loop

An electrical ground loop is when two paths share at least one point where current can flow – this includes power cords for laptops as well as extension cords used to extend their reach! This will make your speakers buzz and it’s a recurring problem.

If you think this is the problem then try unplugging and plugging in any cords that feel loose, removing extension cables entirely from your system, or switching to a new cord for an audio device. You can also use an electrical ground loop breaker – these are often found at hardware stores like Home Depot band are also available at Amazon for a few bucks!

This Hum X ground isolator does the job:

You might find it helpful to do this while listening to music on headphones as well. If the hum stops when you’re using headphones but continues when you’re not then we know there’s probably a grounding issue going on with our computer’s sound card or amp outputting signal back into itself through its power supply (and vice versa).

3. Stop using cheap cables

It’s important to note that a lot of cables and cords for speakers are cheaply priced. This isn’t necessarily because they’re poorly made – but oftentimes these products will have thinner wires which can lead to interference with the signal going into our computer from its sound card (or vice versa).

If you find this is happening then your best bet is switching over to higher-quality audio cables, including HDMI or optical cables, AC cords, etc. which are shielded or have ferrite bread to eliminate interference.

If none of these steps work, continue reading.

4. Avoid frequency interference

This might be a more advanced troubleshooting step but if you’ve tried everything else and your speakers still seem to buzz then something may be interfering with the frequency of our audio signal.

The most common sources of interference are caused by sound waves coming from power lines or a nearby radio station, however, in a house, there can be multiple electronic devices such as WiFi signals, Bluetooth devices, cellphones appliances like refrigerators, or microwaves, and other sources of interference. Many Bluetooth devices such as computer peripherals or the famous Apple AirPods suffer from this problem.

You’ll need to do some investigating here if you’re not sure how your sound system is being affected by outside noise – try turning off all electronic devices in the same room as your speakers for a while and see if that solves the problem! If this isn’t enough then it might be time to contact an electrician who can help with more advanced grounding solutions.

5. Speakers still buzzing? You could have a blown speaker

Sometimes speakers will start buzzing because they’ve been blown out – this could be caused by a defect, an overload on the speaker, or even just too much time playing at high volumes.

If you think that’s the case then it might be best to contact your local electronics store and see if they offer repairs for your particular speaker model. You can also try shopping online for new ones!

Bottom Line

There you have it – some solutions for fixing a speaker that buzzes. Now you can enjoy your favorite song or podcast without worrying about an annoying buzzing sound!

Is your speaker making buzzing sound? Don’t worry. Many people have resolved the computer speakers buzzing issue with the solutions below. So before taking it to the repair store, read on…

Why are my speakers buzzing?

There are many causes for the speakers humming sound issue. One of the common reasons is the electrical ground loop. While frequency interference is also likely to lead to the buzzing sound issue, you can’t ignore the audio output disturbances. Apart from that, the hardware issue can result in the buzzing sound from the speakers, such as your speaker faulty. In addition, the software issue, such as driver corruption probably causes the issue.

Sometimes it’s hard to identify the issue. But you can still try to troubleshoot the problem and fix it by following the solutions below.

How to stop speaker from buzzing sound

You can try these solutions to fix buzzing sound from speakers.

Fix 1: Troubleshoot the hardware problem

As mentioned above, the hardware issue is one of the possible reasons to cause buzzing sound in speakers, so you should check the hardware problem and fix any hardware issue found.

1. Turn the volume control up and down

while connected, turn the volume up and down to test if the sound works properly.

2. Check the audio cable and ports

Check the audio cable and port to see if they work properly.

When the signal cable is disconnected from the ground, an buzzing sound appears from your speaker. Please check your signal input line.

You can switch to another audio cable and port to see if the buzzing sound is disappeared.

3. Check the transformer

The unstable transformer should also arise your attention. If there’s something wrong with the transformer, you can consider change to a better transformer with the same output voltage.

Fix 2: Break the electrical ground loop

One of the possible causes for buzzing sound is the electrical ground loop, so you should break the loop to fix the problem.

You can try to power everything through a single AC socket.

You can remove the cables connecting the receiver or device powering your speakers, and only connect your speakers to have a try.

Fix 3: Avoid frequency interference

It’s common to have many devices near together, but the frequency between different devices can be interfered with each other, such as cordless cellphones, microwave oven and Bluetooth speaker. Therefore, you can check these devices to see if it’s where the problem lies in.

1) Turn off those devices, and unplug the power source.

2) Remove these device close to your speaker.

3) Try your speaker again to see if it works properly now.

In addition, to avoid the electro magnetic pulse, you should keep your speaker far away from strong electrical devices, and wind the wire in the insulation to prevent something like that happening again.

This should solve your buzzing sound issue. If not, don’t worry. We have other solutions for you.
