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 PFL squeaking noise from suspension

    Hello. I've been noticing a squeaking noise every time I drive over a bump. I took the car to the garage, and they confirmed that the suspension is solid. However, they couldn't identify the source of the noise. Has anyone else experienced a similar issue? Any insights would be appreciated.

    "Boing" noise from left rear suspension when turning into a driveway

    I have a Phase 2 Excite 51 (SR) RHD (Australia) and I've noticed that on rare occasions, when I'm turning left over a bump (for example, left turning into a shopping centre car park), there's quite a loud "boing" noise from the back left of the car. It's a pretty comical sounding noise. If...

    Grinding noise at full lock

    Well this isn’t good. 5700 or so miles and 3.5 months into owning and I’ve got a disconcerting noise from the front end (I’m assuming there as it feels like it and it happens at full lock (either direction)) when I corner hard (at slow speed obvs), happens just before full lock and fades in...

    XPower rattle/clanking noice

    I've had my XPower for less than a week and driven just over 400mls. Yesterday out of the blue when driving off from a charge station I experienced what sounded like a wheelie bin filled with empty coke tins being towed along side the car. I stopped and looked all around the car but nothing was...

    New noise - interesting

    The 51kwh ZS went for its first year service at an independent dealer a few days ago (lease company decision, not mine). Interesting, they decided to change the brake fluid, and change the cabin air filter despite that not being the first service schedule. When it came back, I have a new...

    Noise comming from tablier

    Please take a moment to watch the video below. I've been experiencing this issue consistently, and it seems to occur more frequently during rainy or cold weather. I've noticed that applying pressure to the tablier makes the noise stop. Has anyone else encountered a similar problem? If so...

    Wind noise on the driver and passenger side when you get higher speeds?

    Hello, Just be curious if anyone has the same "problem" on their MG4, when I drive more than 80 km/h, it's like the window is not completely closed and I hear some wind noise... Is there a well-known fix @ the dealer for this situation?

    Occasional loud noise when changing gears or (dis)engaging P

    I don't actually know if they're called "gears" in an EV, but anyway. We've had our new MG5 EV (MY2022) for 10 days now. Only about 900 km on the odometer. My only issue so far is that sometimes when I switch between P/R/N/D, it makes quite a loud noise. It doesn't happen every time. Sometimes...

    My car does make some noise

    In contrast to thread Your car should make some noise, my MG4 does make a distinct noise when driving, particularly when accelerating or under regenerative braking. It sounded to me slightly different to the speaker-generated pedestrian alert, more a whine, coming from the rear. It is quiet but...

    Random noise

    Our new MG ZS ev occasionally makes a clicking noise when driving. This sounds like a relay moving, door locking or a shutter operating. It seems to come from the dashboard and happens randomly. The dealer advise us this is the Road Angel taking a picture as a result of a bump on the road or...

    Knocking noise coming from the front sorted.

    I've noticed a knocking noise coming from the front of my MG4 It is more obvious on bumpier roads. Today I decided to investigate having removed everything from the cabin to eliminate stuff. On opening the bonnet I happened to touch things that may be causing said knock and found that the...

    SE SR Under Bonnet Noise suppression

    I saw this mentioned in another thread but can't find it now. I have an early SE SR . There is no suppression material under the bonnet . I'm sure I saw a pic of another MG4 with this material in place . I'm not that bothered because the car is so quiet anyway. But I would like it fitted if it...

    MG HS PHEV - Loud clicking car noise coming from motor - Battery dead

    My brand new 3 month old MG HS PHEV makes a loud clicking noise and then loses all its charge in its 12v battery. Then it won't start again unless jump started. I spoke to a fellow MG owner and he seemed to think that the clicking noise sounds like a starter motor and questioned if the cars'...

    Wind noise over approx 55mph

    As per the title, my MG5 seems to suffer from wind noise - either from the pillar or maybe even from the roof bars. The noise increases on higher speeds, and is silent under 50mph ish. I don't think that it's a problem with the seals, as I can't feel any draught at all. Does anyone else have...
