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. :)

with your ear
Sound can be heard up to the vibration frequency of 16000 Hertz.
The humans hear sounds using their ears. When sound waves enter the ear they go through a process making the sound waves translated from vibrations to meaningful explanati…ons and of course the process requires the help of the brain to translate every sound we hear.
Why do you hear sound produced by the humming bees while the sound of vibrations of pendulum is not heard?
this is because humans have a specific range of hearing that is 2ohz to 20000hz, sound having a lower frequency than 20hz is not audible. The frequency of the vibration of the… wings of a bee is much higher than the oscillations of a pendulum that's why we r not able to hear the sound of a pendulum.
Sound waves too high for humans to hear are called: ultrasonic
If you drop a rock off a cliff and it takes you 3.2 seconds to hear it how high was the cliff the speed of sound is 340ms?
The height is given by s=0.5x9.8xt1. The same height travels a distance s such that s=340xts. On solving the two equations with t1=3.2, we get s=46 m.
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
By ear because sound keep on vibrating until it reaches our ear
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.
Yes. If people can find the differences in other people's voices, then you could indicate the difference in coins. If listened to closely, then you could tell.
Depending on who they were, generally Okonkwo's voice, although sometimes his grunts, his snoring, his advice, or his rage. Rarely, his gun.
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.
Repeated sound waves collide with the membrane of the eardrum, and as repeated procedures go on, the membrane loses its layers, thus reducing the effects of the eardrum's pote…ntial to pick up sound waves. Examples of eardrums being damaged would be exposures to loud sounds such as ipods, heavy metal, and so on.
The second sound Scrooge hears is sound of heavy chains on wood floors. This is in respect of the appearance of Jacob Marley
