Not many people like unexpected sounds coming from their TVs, but unfortunately for some, it’s not just more than an occasional thing. Some people can only find relief when they completely disconnect the audio system from the TV.

In this article:

We will explain the common reasons behind tv sound vibration, and easy things you can do to fix it.

TV Sound Vibration – Is It a Problem For You?

TV Sound Vibration (TV Buzz) is a phenomenon that occurs when your TV emits sounds like snaps, crackles, and pops. This can be extremely irritating and distracting when you’re watching your favourite show.

While most people find this phenomenon annoying, others don’t notice it at all. And while some vibration sounds are normal, abnormal noise usually means something is wrong with your television set

It is thought that the cause of the problem could be related to the way that sound vibrations are transmitted through the air. Some TVs have a built-in vibrating mechanism in the speakers to improve their overall performance, but if this is broken, it can lead to the TV sound vibrations being transferred into its casing.

Tv sound vibration is caused by the internal speaker unit inside your telly. The speaker unit is attached to a subwoofer magnetically, and when this magnet breaks down it can create a buzzing noise through your television set.

The power supply for your TV generates an electromagnetic field. This field can weaken over time and, when it does, it can affect your television’s ability to produce clear, crisp sound. This can also lead to TV sound vibrations and buzzing noise through your telly, as well as affecting its colour picture quality too.

Reasons Behind TV Audio Vibration

Vibration while watching TV is usually caused by faulty equipment, wiring or installation. Before you go out and buy a new TV, check to see if the problem is in the audio source or your TV’s speakers.

1. Bad Speaker Placement

The speakers on your TV should be placed away from the wall, on either side of the screen. The centre speaker should be located directly above or below the screen. The rear speakers should also be placed at a distance from the wall, with nothing blocking their output.

If any of these speakers are too close to a wall or other object, you will feel sound vibrations as well as hear them through the TV’s speakers.

2. Faulty Wiring

If the cables connecting your audio system to your television are loose, you could experience vibrations from poor electrical connections.

To fix this problem, tighten all of the cable ends that connect to your home theatre system and then test it again for sound vibration.

3. Excess Bass Causing Vibration

TV audio becomes distorted due to excess bass (low frequencies). It is not uncommon for the cause of this to be poor installation, or poor selection of speakers by the consumer when they purchased the TV originally.

The solution here is to use a sound equalizer to reduce the amount of low frequency reaching the speakers.

4. Electrical Interference

Electrical interference from other devices in your home can cause a vibrating sound from your TV speakers. The interference may come from an appliance, another electronic device, or even a cellular phone. To find out if something else in your home is causing this problem, unplug all electrical devices and see if the sound goes away.

If it does, plug each device back into a power outlet one at a time until you find out which device is causing the problem. If you find that the sound disappears after you unplug one of your appliances, then contact the manufacturer or service provider of that device to see if there are any updates available to address this problem.

5. Worn-Out Cables

Another possible cause of excessive vibration is cables that are frayed or twisted too tightly at one end (typically at the TV or receiver end). This can lead to signal degradation and/or poor performance in both audio and video departments.

Try re-arranging your cables and/or replacing them if necessary. This may require running new cables, so plan ahead for this possibility during initial installation!

6. Faulty Equipment

You might not have a problem with your speakers or wires, but with your amplifier instead. If you’ve recently had your home theatre system updated or repaired, this could be causing vibrations as well. Test out all your equipment before replacing any part.

7. Moisture in the Vents

This seems to be a common cause of TV sound vibration. It can also cause the volume control to lose its effectiveness. The fix is simple — dry out the vents. First, remove the back panel on your TV and let it sit for an hour or two with the power off.

Then use a dehumidifier (or simply give it time) so that all the moisture has evaporated from inside. Afterward, turn the TV on and test it for sound vibration. If it’s still vibrating, move on to the next step

Troubleshooting TV Sound Vibration Issues

Checking for loose wires and screws is an easy way to troubleshoot an audio problem. Start by removing any cover on top of the TV where you can access any screws. Begin by tightening any screws that are loose or that you notice are not in place properly.

Next, check for loose wires. If you notice that any wires are not connected properly, use a flat head screwdriver to tighten them back into place.

If you’ve tightened all your screws and checked all your wires and they are still loose, you may have to replace them altogether. To avoid having to replace parts unnecessarily, try tightening them one more time before replacing them.

With a bit of luck, this will solve your problem and your sound will no longer vibrate excessively or make other noises causing it to sound distorted.

7 Practical Ways to Stop Vibration From Your TV

The good news is that there are several remedies for excessive TV sound vibrations. They’re simple, inexpensive, and easy to use – just follow these tips to get rid of any annoying buzzing:

1. Clear Surrounding Area

Ensure that there are no objects close to your TV that could vibrate and transfer their vibration to the TV. For example, do not place the TV on a wobbly table or stand; also do not put it on an uneven floor surface or near other devices that might cause vibrations.

2. Use Soundproof Panels (or Similar)

If you still find the sound from your TV too loud or irritating, then consider using acoustic panels or distributed subwoofers around the room. These will help absorb much of the sound produced by your TV and make it less noticeable to other people in the room. Read more about sound diffusers.

3. Bookshelf Assemblies

The easiest way to reduce vibrations is to add a shelf assembly between the wall and the TV. This will not only help to deaden the sound but will also help prevent the TV from falling off the wall if someone bumps into it.

4. Soundproofing

If adding a shelf is not possible, another option is to install soundproofing in the space behind your TV. You can use numerous materials, such as soundproof panels, bass traps, or even an hang a soundproof curtain.

5. Floor Protection

If your TV sits on a wooden floor, this can be another source of unwanted noise. Putting down an area rug under the TV could help, but you may want to consider isolating the floor with either a layer of rubber or one made of thin wood panels that easily fit together.

6. Place Blu-Tack Underneath

Blu-Tack is a sticky adhesive that is safe for use inside your TV, computer, and other electronic devices. Simply apply a small amount underneath each leg of your TV and soundbar to prevent it from vibrating against your surface. It’s not the most glamorous solution, but could get the job done.

7. Place Felt Pads Underneath Each Leg

Felt pads are another great way to stop vibrations from below. They work especially well if you use them together with Blu-Tack for double protection (as shown in the image above).

Cut out 4 squares of the felt pad and place them underneath each of the 4 legs (or 3 if you have a smaller soundbar).

Also, try putting some felt pads on top of the Blu-Tack for extra protection if needed. You can buy felt pads at any hardware store or online store such as Amazon.

Takeaway

The biggest factor contributing to sound vibrations is volume, but the source might come from elsewhere. To solve the problem, focusing on what’s happening can stop TV sound vibration.

Essentially, the only way to stop a TV sound vibration is to stop the source of the vibration. If you can do this, you will have successfully conquered TV-induced sonic wrath.
