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.

    Squeaky rear suspension over speed humps - returns!

    During last winter, a loud rubberised squeak/knock emanated from the rear suspension on the driver's side, in particular when going over speed humps. When the warmer weather arrived, the noise completely disappeared. Except on ONE single occasion, mid July, when I'd driven for miles and miles in...

    A thumping sound heard when OPD is active

    When the OPD is active, a dull knocking sound is heard from underneath, proportional to the rotation speed, when stopping and starting slowly. It is not heard at normal speeds, nor is it heard in normal regen modes. Is this normal when the OPD is active, or is there a problem? The vehicle is...

    Curious about turn-off noises

    A quick question purely out of curiosity . When I pick up my grandkids from school, I park-up and sometimes turn the car OFF from the pulldown menu. After a few minutes there's a series of chunks, clicks, and whirring sounds from under the bonnet, and sounds of fluids being purged. This can go...

    Transmission Whine

    We've had our GT model for nearly 3 months and covered about 1200 miles. I've become irritated by what I'd describe as a 'transmission whine' towards the rear which is obvious when gently coming off the accelerator between 25 to 30 MPH. I'm not sure if it's getting worse, but I'm certainly...

    Noisy Acorns

    Having driven solid German engineering for the last 20-odd years, I was really surprised today to hear the noise of being hit by (what I assume were multiple) acorns. The first time it happened, I happened to be passing an artic in the opposite direction, and I thought he had taken my...

So today I was driving back from work and the rear axle / brakes or something was making a really loud metallic scraping noise - this continued for about 2 miles, I was going over speed humps to try...

    Soundproofing strips for MG?

    Saw these soundproofing strips on Temu & wondered if anyone had tried them, I hear a fair bit of noise on motorways, I know it’s not the same as deadening material but it might help seal some of the wind noise, you have to be careful to not cover door drain holes but the rest looks...

It's developed a clunking noise from the rear passenger wheel when either accelerating (forward or reverse) or when applying the brakes to slow down.

    Grinding/ Scraping Noise from MG5 LR

    Afternoon all. I've just had the most horrendous grinding/ scraping noise coming from my MG5 LR. It appears to be coming from the wheel area so possibly brake discs? The car is nearly 4 years old and had no real problems with it so far, fast wearing tyres aside. It started out of nowhere...

    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.

  17. Transmission/ Front wheels noise below 15mph EV mode
