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. :)

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 adistance s such that s=340xts. On solving the two equations witht1=3.2, we get s=46 m.
because if you was def and u had a dog the dog will bark or pick up the phone and give it to the def person. also the dog might see the flashing light on phone and start barking. there are things in your ear that make you hear.
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 and of course theprocess requires the help of the brain to translate every sound wehear.
What you refer to is called Echolocation and is used by such creatures as Whales, dolphins, bats, some birds and shrews.
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 b…ecause 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.
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 for example.
The vibration from sounds hit the tympanic membrane (ear drum), which in turns causes the ossicles (malleus, incus, and stapes) to amplify and send the signals to the cochlear (inner ear). The cochlear processes the sounds and sends the information through the Vestibulocochlear nerve to the brain.
We hear sound by using our ears,one of the most important part of the ear is the eardrum, it helps us to communicate on telephones, conversations, or we can even use it as what we call 'peripheral instincts'.
You may have a hearing problem. If you have been wearing ear buds and turning up to the highest volume you may have lost some hearing. Go get your hearing checked.
A dangerous sound level is defined as above 85db to cause hearingdamage. Long term exposure to 80 db can also damage hearing.
Although Sound velocity is maximum in solid then why two people in two sides of the wall are not able to hear each other?
Although sound does travel faster through solid media than gaseous, many walls are filled with materials or structures designed to absorb sound energy instead of transmitting it.. In addition to this, sound gives up some energy as heat whenever it travels from one medium to another, so going from t…he air to the wall's surface to the inside of the wall to the wall's other surface to the air on the other side does a great deal to dampen the sound.. The combination of these effects is often enough to lower the intensity of the sound past the threshold for human hearing. (MORE)

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.
Sound vibrations hit the eardrum and consequently produce vibrations in the ear-drum, thence the ossicles (tiny bone levers) in the middle-ear that transmit the vibrations onwards to the cochlea. The cochlea is the transducer, containing fluid that oscillates in the organ in reponse to the imposed …vibrations. In turn the fluid's movement excites thousands of minute hair-cells linked to the auditory-nerve bundle that sends the resulting electrical impulses to the brain for processing. (MORE)
Infrasonic. 'Subsonic' and 'infrasonic' both define sound too low (in frequency or pitch) to be heard by humans without assistance. However, as 'subsonic' can also mean something traveling slower than the speed of sound, and 'infrasonic' only means frequencies below the audible range, 'infrasonic'… is the better answer. (MORE)
Not to low, to high. Like a high pitched sound that only dogs care hear, like a dog whistle.
If one is not deaf one typically has the ability to hear sounds ranging from 20Hz to 20,000Hz. Hearing (or audition) is one of the traditional five senses. It is the ability to perceive sound by detecting vibrations via an organ such as the ear. The inability to hear is called deafness. In humans a…nd other vertebrates, hearing is performed primarily by the auditory system: vibrations are detected by the ear and transduced into nerve impulses that are perceived by the brain (primarily in the temporal lobe). Like touch, audition requires sensitivity to the movement of molecules in the world outside the organism. Both hearing and touch are types of mechanosensation. The answer to this question is not as obvious as it once was. Until a few hundred years ago, the definition of sound was "what we hear". Common sense allowed a little latitude, and allowance was made for distance and deafness, but we all knew what sound was. And then the scientists stuck their oar in once again. Any builder of a church organ knew that if a pipe was made too long the noise started to sound like rapid bumps rather than a musical note, and if it was made too short nothing was heard. The physicists quickly realised that sound was variations in pressure in the air, and that the pitch of a note was simply determined by how many vibrations there were in each second. Too low and it wasn't musical; too high and it could be heard only by children, then dogs and then bats. The scientists wrote papers, then engineers and inventors got in on the act. Now we generate ultrasonic waves at such a high pitch that no creature can hear them; when a pregnant woman has an ultrasound scan she sees her baby, but the only sound she hears is speech from the radiologist.

On a railroad, a pin drops whenever cars couple together. Sometimes, if the engineer was moving carefully enough, he could hear the pin drop from hundreds of feet away.
the vibrations of a sound transmit into the ear then the eardrum turns it into sound THEN it processes it to the brain then you hear it all this happens in about three milliseconds you can hear sound the music and drams
the echoes of the feet from outside, symbolizing the people who are soon to come into their lives.
Generally, most humans are incapable of hearing sounds above 22 kHz. This varies with age, and most people 19 and older can not hear 20 kHz or above. More information (and audio clips) are available in the related link source below. (In order to play the audio clips you must have a computer, amplifi…er, and speakers capable of playing very high-pitched sounds). There are no sounds above 22 kHz on this site because that is (almost) the highest pitched sound that can be represented in MP3 or CD audio format. (MORE)
I heard people who study linguistics are able to identify where you are from by hearing someone talk is this true?
Different dialects have unique features that distinguish them from each other. If you learn those features and know where the dialect originated, you can make an educated guess as to where the speaker comes from.
Yes their is. When you get older, your ears start to degrade. If someone plays a very high pitch tone, their is a good chance you will not hear it.
People who hear a humming, a ringing, or a pulsation may have tinnitus or an ear infection.
I do know that there's at least one picture of Superman somewhere in each episode, and I believe in some seasons there's a Superman magnet on his fridge, but in some seasons it's blank. That's all I know.

Big Ben chimes every 15 minutes but because of traffic noise you would have to be quite close to hear it.
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 potential to pick up sound waves. Examples of eardrums being damaged would be exposures to loud sounds such as ipods, heavy metal…, and so on. (MORE)
When i am playing any high notes above middle C on my clarinet insted of hearing a clear note i can hear a hoarse blowing sound too what im I doing wrong and what can I do to make it stop?
If you want it to be clear, try keeping your tongue higher in your mouth and make sure that when you blow out, blow fast, cold air. Hope I helped !!
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.
sound is a form of energy that can travel from one place to another .sounds are made when something vibrates.
Africa. If you need more specific, mainly South Africa but I don't think it's restricted to that area.
(Not sure if this means 'How do people hear and how do they understand the frequency of sound' or 'How do people hear the frequency of sound and understand it' so I'm answering both.) The ear can be split into three basic parts: outer, middle and inner. At the outer ear, sound waves pass thro…ugh the ear canal and hit the ear drum, causing the eardrum to vibrate at the frequency of the sound waves hitting it . In the middle ear, the ossicles (the 'hammer, anvil and stirrup' bones) transmit the vibrations from the eardrum to the oval window (a membrane linking the middle ear to the inner ear). The middle ear is filled with air, whereas the inner ear is filled with fluid. When sound passes between media of different densities, some of the sound is reflected and lost rather than transmitted. The ossicles help to transmit sound energy from air to fluid with as little reflection as possible. This is called impedance matching, fyi. Additionally, the way the ossicles are arranged allows for a mechanical advantage of about 1.5. This means the forces of the vibrations at the oval window are increased by half. Furthermore, the area of the oval window is around 15 times smaller than the area of the ear drum. Since pressure = force/area, this fact as well as the mechanical advantage of 1.5 means that there is a greater pressure on the oval window due to the vibrations. Essentially, the amplitude of the vibration is increased between the outer ear and middle ear. In the inner ear or cochlea, there is an organ called the Organ of Corti, in which these vibrations are turned into electrical signals and sent to the brain. Within the Organ of Corti there is the basilar membrane, which is what distinguishes the frequencies of sound. The basilar membrane is a stiff structure that is tapered on one end and is lined with hair cells . It is stiffer on one end (nearer to the oval window) and floppier on the far end. When vibrations pass through the fluid in the inner ear, the differing levels of stiffness along the basilar membrane cause different areas of the membrane to resonate at different frequencies. Higher frequency sounds cause maximum vibration (due to resonance) at the narrower, stiffer end of the basilar membrane. Lower frequency sounds resonate at the wider, floppier end of the membrane . There are more than 2000 hair cells along the basilar membrane and they are very sensitive to movement. The vibration of the membrane causes the hair cells to be displaced, and this causes pulses in nerve fibers which translates them into electrical signals that are sent to the brain. (MORE)
Can sounds from past be heard some people say sound never dies because its energy so is it possible to hear maria malibran in future?
No, it is impossible to hear sounds from the distant past. Sound travels in a wave through the molecules of air or water (or any other "medium"). As it travels, it eventually disperses energy to the point that it is indistinguishable from the natural vibration of atoms. It IS possible to hear unint…ended recordings of sound from the distant past (MORE)

Why can't you hear whoosh sound when you open the jar of pickle or peanuts at the second time or can you hear the sound at the second time?
Jars of peanuts, pickles, spaghetti sauce and others, are vacuum sealed at the manufacturing plant. That means that all the air is sucked out of the jar at the moment that the lid is screwed on. This is done to prevent bacterial growth. the whoosh sound we hear is the outside air rushing back into t…he jar when we open it for the first time. When we close the jar, there is always some air that stays trapped in the empty space under the lid. Since air is already present in the jar when we open it again, no air needs to rush in and no whoosh sound is produced. (MORE)
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.
Because your ears have been damaged and the hairlike structures in your ears are compacted back almost.

Bats. They are blind and use echolocation to navigate when they are flying. They emit high pitched sounds humans ears are unable to hear. The sound frequency in a human voice is too low pitched for them to hear.
If you're not under the influence of any drugs/alcohol than you would know if you hit a person, it would be pretty loud even if you were going 10mph.
