Why do I hear marbles dropping in my house?
In other words, water floods through a pipe, compressing the trapped air inside the pipe and creating the initial ‘dropped marble’ sound. As the water flows away or air dissipates, the sound resonates more loudly before fading away, imitating the sound of a dropped marble bouncing on the floor, then rolling across it.
What is the sound of marbles dropping?
Water hammer occurs when water flow is shut off suddenly like when the toilet is flushed. This change in pressure rattles the piping and creates “clanging” sounds, which may sound like marbles dropping after distortion through concrete walls.
Why do I always hear marbles dropping at night?
According to Answers.com, the sound could be created by the change in pressure in toilet pipes. This causes a vibration in the pipes and creates the sound of marbles dropping. A sudden change in water flow mixed with soapy bubbles will create air pockets that burst and echo through the pipes.
What does it mean when you hear a bouncing ball?
There’s no sound, but most people who see it hear a “thudding” in their head each time the bouncing structure hits the ground. This illusion is an example of synesthesia, or when the senses — like hearing and sight — get crossed in the brain, he explained in an email to The Verge.
Why do I hear noises upstairs?
As we mentioned, sound waves from impact and airborne noises bounce in the hollow space between your ceiling and your upstairs neighbor’s floor. These sound waves escape through the ceiling and wall connections and light fixture gaps, letting sound into your apartment.
Why do I hear banging in my walls?
Banging Noises in the Walls The knocking or banging noise you hear coming from your walls usually occurs when air pressure builds in your water pipes. This pressure builds up and causes your pipes to vibrate once the pressure is released (when your faucets are turned on or your toilet is flushed).
Why can I hear the GIF?
Scientists have discovered why a ‘visual ear’ phenomenon lets some people ‘hear’ silent gif images such as the famous ‘skipping pylon’ animation. A new study has suggested the remarkable ‘synaesthesia-like effect’ is caused by interference between areas of the brain responsible for processing sight and sound.
Why does my ear sound like a rubber band?
Joint noise occurs if the cartilage disc is stretched out of its normal position, moves abnormally during jaw movement and then snaps back into position; rather like the sound of a rubber band being stretched and released. The noise sounds louder to the patient as the joint is just in front of the ear.
Why can I hear my neighbors in the bathroom?
Fill up your bathroom If you can hear your neighbors flush the toilet, they can probably hear you, right? That’s because open spaces with tile and hard surfaces, such as a bathroom, amplify sound. “The more you cover your walls, the greater the barrier to sound created.”

Why do HDB flats make noise when water is turned off?
1) When water flow is shut off suddenly, the change in pressure rattles the pipes, which may sound like marbles dropping after distortion through walls. 2) Some pre-fabricated floors used in HDB flats have an embedded high-strength steel cable which can give off creaking sounds when they contract.
Why does my toilet sound like marbles are dropping?
According to Answers.com, the sound could be created by the change in pressure in toilet pipes. This causes a vibration in the pipes and creates the sound of marbles dropping. 2. Water bubbles in sanitary pipes
