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.

    First year done.

    First year of ownership and first service completed, 5313 miles. No problems, save getting the wheel alignment sorted and that creaking noise over speed bumps when the temperature is low. Still very happy with the car, which over the past 3 months has averaged 58.5mpg.

    Noise rear + Mirrors on rear wheels

    Good morning, I bought my Cyberster yesterday, and with the hood closed, I hear a noise as if something's loose in the back. It's not from the trunk; I've already checked. I can't hear anything with the hood open. Is this happening to you? I also wanted to add, is it possible for the mirrors to...

    MG5 Motor whine between 37-40mph plus other issues

    I have another strange noise with my LR Exclusive Which I bought at the beginning of April. When you get to 37mph you start to hear a motor whistle which stops when you reach 40pmh. If you slow down it comes back. If you sit between 37-40mph accelerating and slowing down the frequency changes...

    Hi all, I've read many posts around noisy Air Conditioning with the MG4 when it is turned on, in my X-Power I have the reverse of this. Drive the car and as speed increases a loud flapping noise begins, like a loose air vent cover or alike in the bonnet area. This continues if I turn on the...

    Help: MG ZS EV Cabin Noise

    Hi everyone, I drive a 2021 MG ZS EV Deluxe. Recently I have noticed that the car has a low frequency buffering/vibration noise that really made an almost vibrating noise in my ears. To be honest it’s hard to describe, but it seems similar to the sound wind buffering makes when the window is...

    Air conditioning noise

    I have a noise of plastic vibration from the air conditioning unit next to the driver. If I hit the dashboard, there is loose plastic. I think it comes from the air conditioning key. Has anyone disassembled it? Pictures?

    Drumming / Vibration noise on bad road surfaces

    On poor road surfaces ( more so at low speeds ) there is a drumming /vibration noises from the rear which I had put down to the suspension not being able to cope with the higher frequency jolting and transferring non- damped vibrations into the chassis. Today whilst washing the car , I aimed...

    Weird noise

    My MG5 has started making a strange pulsating droning noise from about 35 mph upwards but seems to disappear at around 70 mph. The MG garage suggested I needed a new set of tires but that has made no difference. I’ve had the wheels tracked the noise still there? Has anybody else experience this...

    Clicking noise from front of car

    We’ve had our MG trophy nearly a week now and are still finding out about the car. Went to get some touch up paint from Halfords 15 mile round trip getting home I noticed a clicking noise from the front . It sounds like a diaphragm type pump maybe for battery cooling? Is this normal?

    Front Suspension Bushings

    Hey So my car has been making a creaking noise going over speedbumps the past few weeks. Got a mechanic to confirm it's the front suspension bushings that are on their way out. Anyone know where to get replacements? Apparently they're a bit hard to find for non-MG garages? Thanks all!
