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.

    MG5 2021 REAR SUSPENSION NOISE

    Some while ago I noticed a knock coming from the rear offside when driving away from cold. After a mile or so it disappeared. Recently it seems to be getting worse. Reported it at 10,000 mile service, told it was just the rear brakes releasing! not covinced. Done another 8,000 miles-still...

    Grinding Noise

    First an introduction - I’ve owned a pre-facelift MG5 LR Excite for about three weeks and have driven it about 650 miles so far. Until today, I’ve had no concerns, and have been enjoying driving it. This afternoon I drove to town, a short six mile journey, and parked in a multi-storey. As I did...

    Wing mirror noise

    Hi, given how quiet driving the MG4 is there is a very noticable wind noise coming from the area of the wing mirror. Its far more noticable than the noise from the front and as stupid as it sounds its worse on the drivers side. Has anyone seen and little trinkets to add on to improve that?

    Whistling noise from rear spoiler (merged)

    [ Moderator: If you have the whistling sound, it's likely to be the rear spoiler; fill the gap as shown in the photo in this post. If you have a rattle from the rear door latch, see these threads (which I may merge eventually): Creak in rear/boot Concerning creaking from the rear left ] Hi...

    Reverse noise?

    I was under the impression that it was good practice to have a reversing noise on EVs. My LR Trophy Connect doesn’t seem to have one. Is there one that I can switch on somewhere? Thanks

    MG5 EV Mysterious Driving Noise

    Hi all, I’ve got an 8 month old MG5 EV SR that I’ve owned for just over a month. Never owned an MG before and never owned an EV. When driving, it makes an odd noise every 5 to 10mins (not regular). It sounds a bit like you’re driving over a rumble strip (quietly) for about a second and I can...

    What is the "BOOP" noise?

    Yesterday, I drove my MG ZS EV for around four hours. Throughout the day, both moving and at a standstill, I kept hearing a "BOOP" sound, as if it was warning me of something. I cannot figure out what this noise is indicating. Any ideas? I've also been hearing a buzzing sound under the...

    MG ZS Aircon Noise

    Hi I’ve bought a second hand 2019 petrol auto MG ZS. I’m happy with it apart from the aircon. Every few seconds I get a hiss. Almost what sounds like an exhale of air or aerosol. It only happens when the aircon light is on. I’ve had the car degassed but it’s still making the noise. Has...

    "Oil canning" noise in the roof - MG5 EV

    Hi, I am having problems with my MC5EV. The roof panel is "oil canning". It clunks when ever the body is stressed - going over the merest bump in the road or even when making turns. MG UK came up with a fix of putting sound deadening foam behind the roof lining. This was done by the dealership...

  14. Engine noise

    Has anybody explored changing the fake engine noise the mg5 makes? Maybe with a box that allows for the noise to be selected.... like those cheap doorbells. Feels like a fun and very achievable little project.

    I'm experiencing a noise from steering column.

    I hear a clunk from the head of the steering column when turning corners or negotiating roundabouts, in fact when the car is stationary and I push or pull the steering wheel it will do it. I took it to a dealer who said that the mechanic couldn't find the root cause of the fault and yet...

    Knocking noise from rear suspension

    Sorry if this isn't a great explanation, but just noticed a loud 'knock' coming from the rear of the car when going over potholes, speed bumps etc. Never done it before. Not sure it would be picked up on a recording if I did one, so trying to explain here instead! It's almost like heaving a...

Speed limit sign on dash not entirely accurate. I had a 124mph display in a 30. We did a 150 round trip doing 65 to 70 mph...
