The most common manifestations are a loud buzz or hum coming through the speakers, or scrolling bands on a TV screen. It could also be a much quieter, yet equally annoying buzz or hum that you only hear when the room is otherwise quiet.<\/p>\n<p>A ground loop typically occurs when one or more pieces of your entertainment system are plugged into your home\u2019s AC (alternating current) supply at different locations, and then connected together by electrical (versus optical) signal cables. RCA, HDMI, composite, component, and similar cables have shielding that\u2019s connected to your home\u2019s ground line. In the simplest terms, this creates a single-loop antenna that just loves to suck in various types of noise via electromagnetic induction. The illustration below shows how a ground loop can be created:<\/p>\n<div class=\"extendedBlock-wrapper block-coreImage undefined\">\n<figure data-wp-context=\"{\" imageid\":\"6920619e84d3c\"}\"=\"\" data-wp-interactive=\"core\/image\" class=\"wp-block-image wp-lightbox-container\"><a class=\"zoom\" href=\"https:\/\/go.redirectingat.com\/?id=111346X1569484&amp;url=https:\/\/legacy-us-images.foundryco.app\/images\/article\/2017\/07\/ground-loop-100729278-orig.jpg&amp;sref=https:\/\/www.techhive.com\/article\/582313\/how-to-get-rid-of-hum-and-eliminate-other-noises-from-your-audio-and-video-systems.html&amp;xcust=3-1-582313-1-0-0-0-0\" rel=\"nofollow\" data-subtag=\"3-1-582313-1-0-0-0-0\" data-domain-name=\"foundryco\" target=\"_blank\"><img decoding=\"async\" data-wp-class--hide=\"state.isContentHidden\" data-wp-class--show=\"state.isContentVisible\" data-wp-init=\"callbacks.setButtonStyles\" data-wp-on-async--click=\"actions.showLightbox\" data-wp-on-async--load=\"callbacks.setButtonStyles\" data-wp-on-async-window--resize=\"callbacks.setButtonStyles\" src=\"https:\/\/legacy-us-images.foundryco.app\/images\/article\/2017\/07\/ground-loop-100729278-large.jpg\" alt=\"ground loop\" loading=\"lazy\"\/><button class=\"lightbox-trigger\" type=\"button\" aria-haspopup=\"dialog\" aria-label=\"Enlarge\" data-wp-init=\"callbacks.initTriggerButton\" data-wp-on-async--click=\"actions.showLightbox\" data-wp-style--right=\"state.imageButtonRight\" data-wp-style--top=\"state.imageButtonTop\"><br \/>\n\t\t\t\t<svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"12\" height=\"12\" fill=\"none\" viewbox=\"0 0 12 12\">\n\t\t\t\t\t<path fill=\"#fff\" d=\"M2 0a2 2 0 0 0-2 2v2h1.5V2a.5.5 0 0 1 .5-.5h2V0H2Zm2 10.5H2a.5.5 0 0 1-.5-.5V8H0v2a2 2 0 0 0 2 2h2v-1.5ZM8 12v-1.5h2a.5.5 0 0 0 .5-.5V8H12v2a2 2 0 0 1-2 2H8Zm2-12a2 2 0 0 1 2 2v2h-1.5V2a.5.5 0 0 0-.5-.5H8V0h2Z\"\/>\n\t\t\t\t<\/svg><br \/>\n\t\t\t<\/button><\/a><figcaption class=\"wp-element-caption\">When you power inter-connected equipment from different AC outlets, you\u2019re apt to create a ground loop: The ground will travel through the shielding of the signal cables.<\/figcaption><\/figure>\n<\/div>\n<p>Anything that breaks the loop will remove the noise, and the easiest way to do it is to power everything through a single AC socket.

It might be audible through your audio equipment or visible on your TV, or it might not. The obvious solution for this type of noise is to not use those types of devices while you\u2019re watching TV or listening to music.

A line interactive UPS is a battery-backup system with a battery that\u2019s always engaged between the input AC and the output AC.

Tripp Lite sent me its model SU1000XLCD UPS to clean up the super-dirty AC in my apartment. That device was selling for nearly $900 when I updated this article. It\u2019s also heavy, about the size of a small dehumidifier, and it has some features (such as USB monitoring, so that it can gracefully shut down an attached computer in the event of a power failure) that have nothing to do with noise elimination. But darn if it isn\u2019t 100 percent effective at providing protection against power surges and outages. The Tripp Lite IS1000HG isolation transformer I mentioned earlier will also clean up AC line noise. It costs several hundred dollars less, but doesn\u2019t provide battery backup power.<\/p>\n<p><span class=\"cta_btn_heading cta_btn_heading_\"\/><\/p>\n<p>It\u2019s also much less-expensive than one of those high-end power conditioners you see marketed to gullible audiophiles.

Tripplite sent me one of these as well: the excellent 1000-watt IS1000HG (Hospital Grade) with four outlets. It\u2019s about $500, but you can easily get away with a lower wattage (500 or 250) model for less than $250.

Poor or loose shielding and other factors can actually turn physical shocks into audio signal. I\u2019m not kidding. I\u2019ve experienced this only once in my life with component-connecting cables and that was for a turntable. But if you\u2019re noticing odd noises that seem to be in time with the bass or vibrations, give the signal cables a hard tap with a finger (with the equipment powered on) to see if this is a problem.<\/p>\n<p>One more wire issue: size. While larger gauge wire can actually help an amp work a little easier and cooler when driving speakers by lowering cable impedance (resistivity), the impact on signal cables is negligible. That is, it\u2019s inaudible to anyone who didn\u2019t pay a lot for a fat wire and needs to hear a difference.<\/p>\n<h2 class=\"wp-block-heading\" id=\"common-noise-problem-4-rf-interference\">Common noise problem 4: RF interference<\/h2>\n<p>Ever wonder why the walls of your stereo receiver and other electronic devices are metal, when it seems like everything else in the world is made of plastic?
