Buzz
Are your TV speakers causing excessive vibration or buzzing noise? This can be quite bothersome and unpleasant to hear. There could be various reasons behind this issue, but fortunately, there are several steps you can take to resolve it. This Mytour article provides guidance on troubleshooting and resolving excessive TV sound vibration.
Essential Information
- Ensure that your TV and speakers are placed on a solid, stable surface, away from walls, electronic devices, or any sources of vibration.
- Use high-quality cables and wires, ensuring they are securely connected and free from wear, fraying, or damage.
- Adjust your sound settings to ensure that the bass level is not too high. Also, maintain a reasonable volume level.
Procedures
Give your TV and sound system a restart.
If the issue has just arisen, a quick restart might fix it. Turn off both your TV and audio receiver or soundbar, unplug them for approximately 20 seconds, then plug them back in and check if the problem persists.
Review the positioning of your speakers.
Ensure that your TV, speakers, or soundbar are positioned several inches away from the wall. Left and right speakers should be equidistantly placed from the TV on both sides. The center speaker should be directly above or below the TV at its midpoint. Any rear speakers should also be positioned away from the walls. Subwoofers should be placed on the floor approximately 12 inches away from the wall.
Inspect the shelving, stand, or wall mounts for your speakers.
When assessing speaker placement, inspect the supporting structures for your speakers or TV. Ensure that if the speakers are placed on a shelf, there are no nearby objects causing vibration.
- Many wooden shelves feature a cardboard back panel that can vibrate due to noise. Move the speakers away from the back of the shelf.
- If using a subwoofer, ensure neither the speaker nor the airflow vent is directed towards anything prone to vibration.
- Ensure the structural integrity of your shelving, stands, or wall mounts. Confirm they are stable and that all screws, nuts, and bolts are tightly secured.
- If your shelving or stands are unstable, consider using blu-tack or felt pads under the legs to stabilize and reduce sound vibrations.
Position a rug beneath your TV or stand.
This is particularly beneficial for rooms with hardwood floors. Place a rug underneath your television, stand, or shelves to absorb sound vibrations.
Lower the bass level.
Excessive bass can induce speaker vibrations, particularly noticeable with low-quality speakers. Built-in television speakers are typically ill-equipped to handle substantial bass. Adjust your television's sound settings to ensure the bass level is below 50%. If issues persist, further reduce the bass level.
- If bass is essential, consider investing in a quality soundbar or speaker system equipped with a robust subwoofer.
Lower the volume.
High volume levels can strain any speaker system. This is particularly relevant for television speakers, often of subpar quality. As a rule of thumb, aim to keep the volume below 75%. If you find it difficult to hear your TV at lower volumes, consider muting other noise-producing devices in the vicinity, such as fans, air conditioning units, or household appliances.
- If even at low volumes, you struggle to hear your television, consider upgrading to a higher-quality sound system with additional speakers.
Implement soundproofing in the room.
If your walls vibrate or sound travels to adjacent rooms, install soundproof panels behind your TV or speakers. In the absence of proper soundproofing materials, carpets, acoustic caulking, rugs, and thick blankets can help mitigate sound transmission. Additionally, consider placing bass traps in the corners of the room.
Reduce the TV brightness.
Many modern flatscreen TVs utilize a set of backlights to illuminate the screen. Excessive brightness on the TV can lead to capacitor overload, resulting in a whining noise. Access your TV settings and ensure that the brightness level is set below 50%.
Inspect for electrical interference.
Interference from other electrical devices can induce speaker vibrations. This may include household appliances, lighting fixtures, and other electronic gadgets. Try relocating or unplugging nearby electronic devices to determine if the issue persists.
Ensure all cables and wires are securely fastened.
Verify that gaming consoles, streaming devices, and external peripherals are properly connected to the appropriate ports on your TV. Experiment with different HDMI ports and cables to troubleshoot. If utilizing external speakers, ensure the speaker wires are firmly attached at both the receiver and speaker ends.
Opt for higher-quality cables.
Inferior cables often lack sufficient shielding and are prone to rapid deterioration. This can lead to increased electronic interference. Check your cables for signs of wear, fraying, or damage. Consider replacing them with higher-quality alternatives to see if this resolves the issue.
Eliminate moisture from your TV screen.
Excessive moisture levels in the environment may contribute to TV sound vibration. Try removing the rear panel of your TV and allowing it to air out for some time. Alternatively, use a dehumidifier to reduce excess moisture levels. Reattach the TV panel and observe if the issue persists.
Contemplate upgrading your speakers.
If you've exhausted all options and your speakers continue to vibrate, it might be time for an upgrade. Fortunately, you can easily upgrade your speakers with a budget-friendly soundbar or speaker system.
- If you observe vibrations even when the volume is muted, it's typically indicative of speaker malfunction.
