Are you worried about the buzzing sound of speakers? There is no need to worry because annoying buzzing from speakers is common nowadays. Fortunately, this sound issue is solvable. The buzzing sound issues may cause for several reasons. Some common reasons are as under:
- The electrical ground loop
- Frequency interference may lead to a buzzing sound problem.
It is impossible to ignore the output disturbances of audio. Moreover, hardware issues may result in the buzzing sound from speakers. Sometimes, corrupt drivers become the main culprit of software issues.
In numerous cases, it becomes hard to recognize the issue. You can try some solutions to troubleshoot this problem. Here are some possible solutions.
How To Stop Speakers From Buzzing?
Evaluate the Volume
Buzzing speakers become an actual nuisance. Sometimes, an issue can be minor and easy to solve. In the first step, you have to check the level of volume. It must be almost 75% of the maximum capacity of speakers. Make sure to adjust the volume of speakers and see if the issue is resolved.
Check Port and Audio Cable
The port or audio cable may be the reason for the buzzing problem. You can switch to a new cable or port to find out if the problem persists. With this procedure, you can identify the main culprit.
Troubleshoot Hardware Issue
The hardware problem is a possible reason behind buzzing sound in speakers. Make sure to evaluate the hardware issues and fix any possible issues. Turn the volume down and up to test the sound.
Evaluate the port and audio cable to find out if it is working appropriately. A buzzing sound will appear from a speaker if a signal cable has no connection to the ground. You can check a signal input line. Feel free to switch to a new audio port or cable to see if the problem is solved.
An unstable transformer can take your attention. If you are noticing something wrong with a transformer, consider changing it with a better transformer. You will need a new transformer with a similar output voltage.
Closely check the audio driver of your speaker because corrupt or faulty drivers can cause a buzzing sound. Sometimes, you can update drivers manually. This troubleshooting method may take more time. In this situation, you have to find out the right driver.
Updating drivers may be a delicate process. Installing or downloading an incorrect driver can be the reason of serious malfunctions. The wrong software may increase boot issues, lags, and crashes. To avoid these problems, carefully choose a driver.
You can use an integrated device manager tool. It will automate the procedure of updating an audio driver. Remember, this option is safe and allow your operating system to search for compatible drivers. In this way, you can decrease the danger of human mistakes.
Fix the Ground Loop
A ground loop can be the main reason for buzzing noise from speakers. Remember, a ground loop is about a clash of ground potentials of equipment or AC sources. It brings visual or audible hum.
In this case, you can buy a ground isolator. After resolving buzzing issues, it is possible to enjoy the best audio again. Remember, a ground loop is regular in entertainment equipment. It may occur if more than one piece of equipment is plugged in alternating current (AC) in different areas.
Different devices are connected through electrical signal cables, such as HDMI, RCA, and component and composite. The shielding may have a connection to the ground. In simple words, it may create one single-loop antenna that sucks in different types of noises through electromagnetic induction.
Any damage in the loop can remove the noise. The easy method to do this is to power everything through an AC socket. Plug all equipment in a power strip, power center, or surge protector and plug these things into a wall outlet.
Several multimedia setups may be handled by a 10-amp circuit and several household circuits. Sometimes, it can be challenging to reach a similar outlet with equipment. Subwoofers and self-powered speakers may be the main issue.
Pull the ground with the use of a three-prong and two-prong adapter. It may increase the chances of shock hazard. If you can’t use an extension cord, feel free to purchase a hum eliminator.
Avoid Frequency Interference
Nowadays, homes have modern gadgetry. People have different devices for dancing and singing. These things may be the reason for tenacious frequency intrusion issues. If you are facing this issue, turn off the devices and unplug any of them put in proximity of buzzing speakers.
Sometimes, removing these devices may help you to resolve the problem. Try to switch devices that are the main culprit of buzzing. Make sure to keep your speakers away from any device that can trigger the buzzing nuisance.
Tweak Audio Settings
If you are unable to solve the buzzing issue, you can try tweaking audio settings. Here are some easy instructions:
- Open the “Start menu” and move to “Control Panel”.
- Tap on “Hardware” and “Sound” section. Now click on “Sound”.
- Check the “Playback” tab and local speaker device.
- Now right-click on speaker device and choose properties.
- Navigate to the enhancements tab.
- You have to locate the “Disable” possible enhancement options. If this option is checked, it is essential to uncheck it.
- Finally, click on “Apply – OK” to save changes.
Noise in AC Line
Ground loops may not be the culprit of electrical noise. A device with a motor, such as blenders and hair dryers, can increase buzzing sound. Moreover, failing fluorescent fixtures and light dimmers may create this interference.
It is audible through audio equipment or visible on TV. If you want to become a part of some Benjamins, assure yourself for pristine AC without any ground-loop noise. Feel free to use an online UPS and an isolation transformer.
You can use a battery-backup system to engage between output AC and input AC. It needs electrical power for conversion between AC and DC. After transformation, you can notice a change in noise level. This procedure is known as double conversion.
How To Fix Buzzing Speakers?
If buzz or hum is coming from the speaker, here are some easy steps to follow. It is essential to discover the reason for buzz and cure it.
In the first step, you have to determine the type of hum. Two basic types include 60Hz hum because of poor shielding and 120Hz buzz by ground loops. Sometimes, reasons may be proximity to magnetic fields and cable problems.
Turn down and up the volume control. It will help you to manage the buzz in the speaker. Choose different inputs and find out if buzz goes away. Check it with different available inputs.
Disconnect different inputs and find out their effects. Remove all the cables connecting the power amplifier, device powering speakers, and receiver. The speaker cables, AC plug powering your unit and loudspeakers.
If the problem is not solved, you can check video feed, turntable, and CD players. These things may increase the chances of buzz. Remove these pieces from the amplifier and receiver. Removing all the inputs may eliminate the hum.
Ground loops may be expected if video equipment is connected. This problem is common with cable TV connections. Try to reconnect each source one by one again and listen to buzz to return. It will help you to find out offending equipment.
Sometimes, cable TV connection becomes the reason of humming. In this situation, you can contact a cable company to isolate the transformer from your cable. Feel free to purchase a TV isolation cable transformer. These are available at numerous stores.
Check for the power ground loop among two tools if cable TV is not the main reason for the problem. An AC (cheater) plug proves helpful to lift the ground of the third wire from the AC receptacle. Feel free to use ground isolator that is effective and safe. For safety reasons, you should not run your equipment underground.
You should not run power cables near or across video or audio signal cables to stop buzzing from speakers. Modern lines for signals are well protected. If you are getting the buzz from the speaker, it may not be a ground loop.
The cable running non-Wi-Fi (self-powered) speakers are audio signal cables instead of output cables. Moreover, three-wire balanced cables (two signals having inverted polarity) may be less susceptible to buzz in the power cable and other types of noises.
Sometimes, the equipment allows you to use balanced inputs or outputs. Speaker cables must not be affected audibly. For your safety, keep AC cords secluded. Moreover, you should not loop antenna signal cables that may induce the noise.
Electromagnetic induction can be a problem. The cable quality is essential to consider. Remember, poor cables may increase noise issues. There is a misconception that expensive metal can be a guarantee of high-quality cable. This concept is wrong because gold on connectors can’t oxidize.
Gold is better than chrome and nickel, but it may be worse than copper and silver. Copper wire and gold connectors may make a great combination but avoid overly-hyped cables.
