noise
Noise is unwanted sound considered unpleasant, loud or disruptive to hearing. From a physics standpoint, there is no distinction between noise and desired sound, as both are vibrations through a medium, such as air or water. The difference arises when the brain receives and perceives a sound.Acoustic noise is any sound in the acoustic domain, either deliberate (e.g., music or speech) or unintended. In contrast, noise in electronics may not be audible to the human ear and may require instruments for detection.In audio engineering, noise can refer to the unwanted residual electronic noise signal that gives rise to acoustic noise heard as a hiss. This signal noise is commonly measured using A-weighting or ITU-R 468 weighting.In experimental sciences, noise can refer to any random fluctuations of data that hinders perception of a signal.
Good morning all,
I have a Cambridge Audio 851W power amp which makes a random clicking sound - Just wanted to see if anyone knows this is normal or a sign that something could be wrong.
The noise is similar to the noise that happens when you first turn on any of the components (power amp, pre...
Hi, my amp (a Yamaha RX-A3050) appears to have an issue. It was working fine until earlier today, when after being on for maybe 2-3 hours, it suddenly switched itself off and gave a loud popping noise. I tried switching it back on again, only to have the same thing happen immediately.
The...
Long story short. We have an open air pub quite close to us. Shortly after they opened they started playing music which just got louder and louder. It was unbearable. Eventually the council slapped a noise abatement order on them and the situation improved. After a while they closed down and put...
I have an old Optoma HD67n that has been sitting dormant for a while. I had an idea to use it outdoors but upon testing it, discovered that it is making a right old racket. When first started it is quiet, the menu screen, again quiet. As soon as a source is detected, in this case a Sky mini...

Hello. New to the forum.
Just purchased a Sony A80K 65" after my 12-year old plasma finally quit. Loving the TV so far. Wall mounted with simple Sanus VESA tilt mount. Used the included Sony wall mount attachment hardware. All is good...

Hi. I recently (3 days ago time of the writing) purchased an Hisense 32A5KQ. It's a QLED Smart tv running VIDAA.
First day it arrived, I unpacked it, fit it's feet (I think it is really a nonsense this kind of arrangement, I would prefer every tv to have a metallic central stand-off and use the...
Having replaced my PS 4 pro because at times it was like having a heavy duty fan running I've noticed the fan on my PS5 is annoying me as it seems to run all the time, any suggestions as to what I can do to silence it?
Hi all
Am about upgrading my Sony5000 to 7000 and worry about the noise, although 5000 is not very quiet, I can live with it but I hope 7000 is not noisier if not more quiet , as projectors are almost above seating and most of the time I'm watching moderate volume its very important...
Hi, I have a question re bass noise coming from a subwoofer. My upstairs neighbour has subwoofer on a wooden table on a wooden floor. Although the volume is low I can hear the bumping bass noise through the ceiling.
I was wondering if there is a cheap solution that can reduce the bass...
Everywhere I go I hear the same bird noise outside the window. Obviously it's hard to describe in text but it follows the same pattern - ooo ooo, ooo, ooo ooo, ooo (two ooo's, a break then one ooo repeated). Anyone know what it is?
