Marbles Going Through Pipes Sound

This phenomenon has been in the news lately.

Marbles going through pipes sound.

It all started when the straits times forum published a letter by bank executive joseph wong who kept hearing the sound of falling marbles in his flat. A sudden change in water flow mixed with soapy bubbles will create air pockets that burst and echo through the pipes. This causes a vibration in the pipes and creates the sound of marbles dropping. Building experts told us that it s due to the pipes mosquito traps or vibrations that go through the walls.

They say the sound comes from water trickling through pvc pipes which gets distorted through concrete before emerging as the sound of falling marbles. The pipe bounces back up falls back into place the sound occurs and the cycle repeats a couple of times though there is less force each time. You ll build a roller coaster track for marbles using foam pipe insulation and masking tape and see how much of an initial drop is required to get the marble to loop the loop. The sound it creates is similar to that of marbles dropping.

However this usually produces a single sound. If the sound alters as it moves through a building it means actual marbles and pins can t be the root cause. Soon after a few cycles the force is too small. Pipes making sounds that sound so much like marbles.

Can you find a correlation. Then again think about this. Plumbing is a good. But this makes pinpointing the origin even more challenging.

Air can get trapped in the network of pipes as water passes through them and the force can cause the pipes to jostle and disperse the air pocket creating a sound like marbles rolling. The sounds are primarily coming from the pipes in most cases. This change in pressure rattles the pipes and creates clanging sounds which will sound like marbles dropping as the sounds pass through concrete walls.
