What is the marble dropping sound you hear in your walls or from the apartment above you this is the second DC apartment you have heard it in and apparently people in Singapore hear this too?
Water hammer occurs when water flow is shut off suddenly like when the toilet is flushed. This change in pressure rattles the piping and create 'clanging'sounds, which may sound like marbles dropping after distortion through concrete walls. :)

Sound can be heard up to the vibration frequency of 16000 Hertz.
The humans hear sounds using their ears. When sound waves enter theear they go through a process making the sound waves translatedfrom vibrations to meaningful explanations an…d of course theprocess requires the help of the brain to translate every sound wehear.
your ear hears sounds through a wall because of basic physics. when a noise is made, the air particles move. the particles then transfer the engery they received onto another …particle. this process continues till you can hear the sound (till the particles reach your ear) you can hear though a wall because the particles in the wall absorb the motion and transfer that motion onto other particles passing the sound through.
If you drop a quarter dime nickel and penny using the scence of hearing bliknd folded can yolu tell them apart?
dont awenser these questions their lies i dislike this website dont go on here
I live in a third floor apartment and I hear something moving in the walls do rats climb up to the third floor or do they mainly stay in the basement?
norvigien rats can swim very well while regular tree rats climb very well. both can end up in the walls of a 3rd floor apartment
No. There is a frequency range in which people can hear. Very high frequency or low frequency sounds are inaudible to us, but can be heard by some other creatures, like dogs f…or example.
Sound waves hit the eardrum and cause it to vibrate, those vibrations travel through the inner ear through a series of small bones and nerve endings that send those signals to… the brain.
Not to low, to high. Like a high pitched sound that only dogs care hear, like a dog whistle.
yes. like a dog whistle
infrasonic because they are below the range of human hearing (below 20 Hz)
I have no idea who answered this question I don't know who would search for it. But I'll tell the answer anyways even though everybody knows is by their ear.
S=ut+0.5*a*t 2 s=displacement u=intial velocity=0m/s t=time=7seconds a=9.81m/s 2 s=0*7+0.5*9.81*7 2 s=240.345m
12hz -20000 hz.
Not usually, 15-22 kHz is the upper limit in normal hearing.
