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.

    LR Exclusive A/C fan noise

    Hi, I have had my SR Excite for four years and have now bought a LR Exclusive. The LR has full A/C so can't compare to my SR but the fan when on full makes quite a noise is this normal?

    Light grinding/scraping noise (ZS EV Mk2)

    Went to go out for an hour this afternoon but the car seems to have developed a light grindy scraping sound when going forward, its worse at full lock and not present in reverse. Its not terribly loud, just a bit worried its running gear. Can't get to the dealer until mid May (!) Any ideas?

    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?

    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!

It's hard to pinpoint exactly where it's coming from but it happens when going over bumps or quickly steering left and right.

    MG ZS EV MK1 Wiper noise

    I have booked my 69 plate ZS into the dealer as the wipers seem to be making a noise under the scuttle panel like a knocking noise when they move. Anyone had anything similar and know if it will be fixed under warranty?

    Noise coming from MG4 Standard's Back

    Hello everyone! I have been a user of an MG4 Standard for 15 days, the car now has 450km. I have a question about a noise I notice, it comes from the back of the car, I would say the engine area. It is a very faint sound, it can be heard with everything turned off, neither music nor the air...

    Grinding noise on full lock

    I’ve had my new MGZS Hybrid Trophy since 20th November. Within a week or so of getting the car it started making a grinding noise when in full lock. I was told it was due to rust developing on brakes while standing outside prior to delivery. It then developed a rattling/vibration noise as well...

    Grating noise

    There's a slight grating noise between releasing the acceleration and freewheeling. It disappears when you apply gas again. As if it is switching from one mode to another? Anyone had the same noise. Seems to come from left hand side of the car.

    Horrendous noise!!

    Hi. Long time since I posted but thought I’d ask you experts 😊 Drove my car earlier today and it was making a horrendous grinding, whirring, banging noise, the sort of noise you’d expect if an exhaust was hanging off but obviously it doesn’t have one! It went on for about 5 minutes, people...

    Knocking/grinding noise on very gentle acceleration or feathering the throttle

    New issue - a rather disconcerting knocking/grinding from the front (possibly passenger) side when applying the lightest of acceleration. Disappears when you increase acceleration or decelerate. Got my first MOT in a few weeks, so has anyone else had this?
