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.

    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!

    Knocking noise in the rear

    Hi All, I've noticed a knocking noise coming from the rear of the car. It's hard to pinpoint exactly where it's coming from but it happens when going over bumps or quickly steering left and right. I have removed everything from the boot of the car (including puncture kit and foam), the parcel...

    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?

    MG4 Ticking/Rattling Noise Coming From Behind The Steering Wheel

    Hello, my car is an MG4 Luxury with 21,000 km on it. At 20,000 km, a ticking noise started coming from behind the steering wheel. The noise appears at around 15 km/h and becomes inaudible at 60 km/h. It is definitely not a trim noise; it's a mechanical sound, but I haven't been able to figure...

    My MG5 LR 2021 has been making a rumbling noise from the front of the car.

    MG Basildon have seen my car and heard the noise and believe it to be the reduction gears. I bought the car new from them and it has just had its 3rd service with them. A week ago they informed MG about the problem but have not received any communication from MG about the next move which I...

    Cable snapping under the dashboard ?

    Hello Since I got the car in July, everything was pretty silent and calm in the cabin. But since 1 or 2 month a new noise has come. It's like one or more cables making a "tac tac" noise under the dashboard, located somewhere near the part where the windscreen and dash join together. It also...
