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.
How to stop/cure the high pitched noise bathroom sink that stops when water turned on but then starts again shortly ( time varies ) after water has been turned off. Do not know if relevant but I noticed if I turn on the cold water only, there is first a entirely different lower like noise for...
There is a noise coming from my neighbour's house through the party wall. Sounds like a pump of some sort. They have had a new ensuite installed recently and also a pipe from first to ground floor was leaking and they had it repaired. The noise comes and goes every couple of days. When it is on...
Has anyone tried lining joist notches with a low friction, high temperature resistant material to prevent the bangs when a pipe expands and momentarily sticks on the joist?
Hello, when our hot water comes on in the morning and evening there is a deep grinding noise which lasts less than 5 minutes and then stops. After that, all is well. We have a combi boiler.
Thanks.

Hi All: I have always appreciated your comments and troubleshooting recommendations. If I may ask for your thoughts on the following:
I have and older Orbit WaterMaster valve. Please see attached photo. I have 4 of these valves in the manifold. I have replaced the diaphragm on all 4...
Hello
I have no experience in this industry. A few years ago our home was completely stripped apart, remodelled and extended. This required new hot and cold water pipes all over the house, a larger boiler, larger tank and so on - see attached. We wanted the water tank to go into the loft but...
Hi, we're having an issue with our toilet in which only for the past few weeks a slight hissing sound happens 24/7. It sounds something is running through the pipes although there's no clear signs in the cistern or with the water meter etc. It isn't that loud, but certainly noticeable with no...
When I turn on my hot water taps anywhere in the house, after about half a minute there is a humming noise all around the house. When I turn on the cold tap, the noise stops. Any ideas what is causing this humming noise?? Thanks Michael.
A constant ‘hum’ noise has started and I’ve traced it back to the water meter in the street in front of the house. The noise internally can be heard from the stopcock and you can feel a bit of vibration in the pipe work around the stopcock. The dials on the water meter are dead still when there...
Hi. First time poster.
I've just had a new bathroom fitted in my loft and am having an issue with noisy taps - modern mono mixer. Not water hammer, but when they are half on they make a noise that I find unacceptable, yet my plumber insists this is just the way it is. However, my other taps...
Hot water system making a very high pitched squeal. Very loud when using the bath upstairs, not as loud in the downstairs kitchen but water pressure has dropped. My step dad (not a plumber) has changed the combination valve but no luck. Any suggestions? Thanks! Attached are videos of the noise...
Hi, We live in a bungalow. We are awaiting a plumber to check for water hammer but not sure if there are other things that may be causing the noises in our property. There is a booming noise about every 10 seconds followed by an echo. It starts at random times during the day and continues well...
I have moved into a house with a Joule Cyclone CY200L indirect cylinder in my loft. Recently it seems to continuously be making a noise, as if it's filling up or heating up, I'm not sure which.
The thermostat on the side is set to 55, when I turn it below 50 there is a click and then the noise...
I have an intermitent buzzing noise that is coming from my boiler. The sound is coming from behind the door panel in the vicinity of where the flame occurs. The only other electronics in this area is the gas control valve and the main control panel module. The sounds seems like it may be coming...
We have a Grant condensing oil fired boiler in good condition and four years old.
Sometimes after a period of use when the central heating has been on, we can hear a rhythmic sound from the pipes and the boiler is not firing up as it should Leave it for a while and turn up thermostat and it...
Hi,
When I turn on the central heating, the boiler makes a loud strange pulsating noise. It doesnt happen when the hot water is turned on, just the central heating. It sounds quite dangerous, like its going to explode. It doesnt always happen as soon as the central heating is turn on, sometimes...
I wanted to start a new more dedicated thread as I am on about 3 just now in one way or another trying to get up to speed with my problem. The issue is that my Gledhill Stainless Lite indirect unvented cylinder makes loud noises when heating - this is a bit random, but that noise is loud enough...
