Should a 50-inch LCD TV be making a humming noise?
Some of the larger TV's are DISH ready, meaning that they have the tuner inside for SAT TV. The SAT tuners often have an internal fan that makes a humming noise. If it sounds like something other than that, you might have a bad component in your sound circuit that allows 60 HZ hum through the speakers. If it is a rear projection LCG TV it has a fan in it to cool the bulb. You will hear the fan if you listen closely. It usually cannot be heard over the volume. i think the fluorencent bulb and electronics inside make humming sound naturally. Kinda like when you turn on a lamp, and some lamps make a low humming sound. Another thought. A low hum with no sound on in an LCD flat panel TV, if not a fan sound which you can hear the speed pick up as you turn it on, can be a transformer or coil hum that may be normal, but the level of the sound might indicate the panel itself is the cause. Too difficult to express the actual level that is not a concern. If it's anoyingly loud, have it checked by a professional. Hint, lower the following adjustments to aid in diagnosing. Brightness, contrast or Picture, and backlight, if it has that feature. Pick an unused port with no information showing to see if it is there too. This helps a tech to understand more. Also if noise is more noticeable on one side of the TV.
What happens to electricity pylons in the summer?
Usually in summers due to high temperatures conductors became lengthy due to it pylon has to sustain more pressure of conductor weight and hot windy conditions thus there will be more vibration and humming sound in pylon can be visible.
How do you produce electricity with the help of sound in a simple way at home?
The easiest way is by use of a microphone. Another way is with an electric guitar pickup.
What is digital sound?
Digital sound is a rather silly name. Digital refers to how the sound is stored, as a huge number of ones and zeros. Ths stream of ones and zeros can then be fed as instructions to something like a computer, or something that works like a computer, and the computer will understand the instructions and turn them into something called an analouge(or analog)electric signal which then can be turned into sound by a set of headphones or speakers. Sound, the "thing" that we hear, is never digital.
