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.

    Clicking Noise

    Hello, We are due to pick up our new MG5 #teamblue, this Saturday. Dealer rang to say they are preparing the car and they are having issues trying to charge it. It is making a clicking noise when they try to trickle charge it. Any idea what the problem might be? Thanks in advance.

    Whining- Motor/gearbox noise

    Do any of you technical people know exactly what causes the light whining noise (which is normal) on our cars? Is it the electric motor bearings? Is it the transfer gears within the electric drive transmission system? I know that a lot of electric motors these days are near silent.

    Low speed wind noise - roof bars?

    Does anyone get wind noise at low speed (up to about 30mph) from the roof area? I’m guessing it’s the roof bars? It seems worse on some days than on others.

    Creaking noise from Steering Column

    Forgive me, but I think there was an earlier thread suggesting this, but at that stage, it didn't affect me. But now, at just over 8,000 miles, I've developed a really annoying creaking noise from the Steering Column. The strange thing is when I switch the car off and turn the column left and...
