sounds

In physics, sound is a vibration that propagates as an acoustic wave, through a transmission medium such as a gas, liquid or solid.
In human physiology and psychology, sound is the reception of such waves and their perception by the brain. Only acoustic waves that have frequencies lying between about 20 Hz and 20 kHz, the audio frequency range, elicit an auditory percept in humans. In air at atmospheric pressure, these represent sound waves with wavelengths of 17 meters (56 ft) to 1.7 centimetres (0.67 in). Sound waves above 20 kHz are known as ultrasound and are not audible to humans. Sound waves below 20 Hz are known as infrasound. Different animal species have varying hearing ranges.

    Boiler making banging sounds and pressure fluctuates

    Hi, We recently moved into a new rental property and have had issues with the heating. The house has a Baxi boiler, and when we moved in it wasn't working, with an E119 error, but this was easily fixed with topping up the water. However, about twice a week I need to do a top-up, so there must...

    Unvented cylinder constantly sounds ‘on’

    Hi, I have an unvented cylinder and lately even without the boiler central heating or hot water ‘on’, the system sounds like it’s constantly ‘on’. All through the night, it used to be silent except when running, but now it can sound like it’s ‘on’ constantly for days at a time. Surely this...

    My central heating sounds like it is on when it isn’t

    I have a conventional heating system. Had boiler replaced last August and since then my heating has made a humming noise - even when it is off. Had British Gas come go look at it but couldn’t hear it. I asked if it may be something to do with tanks in loft, but he said no and wouldn’t even go...

    Leaks and odd sounds (or lack thereof...)

    Hi folks, I apologise that what I ask might be very uninformed and silly, but I have to admit to having virtually no DIY skills or understanding of plumbing systems whatsoever! The other day the radiator in my kitchen began to make a hissing sound that did not cease when the radiator was bled. A...

    Need advice around these clicking sounds. I posted last week, but I didn’t get much luck. This I have recorded the sounds. The sound appear to be around my toilet, but I don’t think the toilet is the issue but something behind toilet - in the wall and probably a pipe. Hope you can help me...
