What is the high pitched humming sound often heard in an otherwise empty and silent room?
its just your brain increasing its sensitivity to noises. it could almost be considered a noise floor, or possibly the blood vessels in your ear. as red blood cells pass through the capillaries, they bump the walls a bit, causing minuscule vibrations to the eardrum.

When I drive my 97 Honda Civic it makes a metallic high-pitched scraping sound much like the sound often heard when buses or trains stop. The noise stops as soon as I hit the brake pedal. Brakes?
Answer . This is most certainly your brake pads. On Honda brake pads there is what is called a squealer, a small metal piece that causes that sound you are hearing when your pads get too low. Your best bet is to take your car into a Honda dealer and have them replace your pads and check your rot…ors. Do not take your car into a midas or gateway because their pads will continue to squeal due to the metals they put in their pads. Also a Honda dealer will replace your pads if they start to squeal within their warranty period. (MORE)
There are many high pitched sounds. Some of these include breakinga glass, a young child screaming, as well as a bird singing.
What causes a high pitch humming noise similar to blowing across the top of an empty beer bottle when turning right on a 05 Grand Caravan especially accellerating through the turn?
\n. \nmy 2003 g/c sport 3.3 makes a whinning noise similar to your "high pitch humming" and both may be the alternator whirring. It seems worse when cold, but there are no other associated problems, although the sound comes and goes.\n. \n. \n. \ncould be low power steering fluid or air in steer…ing system, check fluid level if full turn steering wheel all the way to stop in both directions(do not hold at stop)this should push air back to reservoir (MORE)
High pitched sounds are caused when sound vibrations vibrate at ahigh frequency. High pitched sounds can come from instruments suchas guitar.
If the high frequency sound is within hearing range, you can hear it as a high-pitched sound. If it's out of the hearing range you can't hear it, of course.
2005 trailblazer makes a high pitched noise harder i push the gas higher the noise heard it could be the alternator because its a high output type sound right?
Just had the same issue.....it is quite possible your water pump. try this look at the fan located near the belts. If it moves when you tug it, then it is definetly your water pump.But before you dive in to replace the water pump or the alternator, first remove the serpentine belt idler located unde…r the alternator. Find an auto parts store that carries bearings (About $13.00 to $15.00) and have them press a new bearing into the idler housing. Re-install and test engine for high-pitched noise. If noise is gone, you just saved yourself a lot of time and money. A replacement alternator would have cost about $200.00 from a parts store and maybe $300.00 from a dealer. If you try to buy a replacement bearing from a dealer they will offer you a complete idler assembly for around $50.00 and you have to remove the alternator to replace the idler assembly. Of course if the noise doesn't go away, then you are out only $13.00 and have to replace the water pump or alternator anyway. Personally, I would replace the alternator next because it's easier to get to than the water pump. If that doesn't get rid of the noise, you can take it back and get the water pump. I just went through this with my 05 TB. The idler was the problem. (MORE)
This is called the Doppler effect. A sound-producing object coming closer will sound louder than a sound-producing object moving away. The speed of this moving object effects how much this is noticeable. See link in the discussion area.
Because the rate of change in the pressure in the air differs: high pitch has a rapid vibration, low pitch a slow vibration. Humans can usually hear from a low of 20 Hz (cycles per second) to 20,000 Hz. I'm so old that I do not hear much above 12,000 Hz any more.
High pitch = high frequency = short waves = comes from something moving fast Low pitch = low frequency = long waves = comes from something moving slower
Shorter wavelengths, higher frequencies makes high pitched sounds. Take a rubber band and cut part of it; hold it between your fingers and stretch it slightly; strum it. You will hear a low sound. Pull it tighter, and strum it. It moves faster, and the sound is higher. Low frequencies sounds …low. Thus the slower movement of the rubber band. Higher frequencies are faster. ^v^v^v^v^v^v^v (MORE)
quite a number of routers either have this fault straight out the box or develop it after some time. I have seen it in all major brands of warying types and function. It varies in intensity from barely audible to quite loud in some cases, and is usually ranges from between 8-20khz. It may vary in t…one and volume with load or traffic, or it may be constant. Most people believe it is the power supply unit (adaptor) or induction coil that has come lose, but this is actually inaccurate. Most of the time this is a semiconductor problem that cannot be cured. Your main options are 1.) if it is a new device, return it and get it replaced. 2.) If it is an older device out of warranty you could relocate it to another room, or cupboard under the stairs (or similar) where it won't be such an issue. 3.) you could replace the unit. (expensive yes) but quite often these high pitched noises cause irritation, distress and headaches sometimes without the user even realising the router is the cause. 4.) you could enclose it in a ventilated sound dampened enclosure, though I reiterate it must be ventilated uless you're happy of running the risk of setting your home on fire. 5.) smash it with a sledgehammer for satisfaction, especially if (as in option 3) you have been distressed by the noise. Most of the components that cause the issue are surface mounted and not easily replacable. I have seen too many people guessing/speculating about the cause of this problem but RARELY is it a power supply or induction coil or any other component that a standard electronic serice engineer would be prepared to fix.

If you are signing in an (otherwise) empty room the sound will echo around you and will possibly sound high-pitched. If you are signing in an empty room then the room isn't empty.
It all has to do with the shape of a room. A famous example of this is a room where someone could whisper at one side of a room and be heard by someone at the other end.
Hypertension is called the silent killer because most people do not realize they have hypertension, resulting in many serious complications without any early symptoms. This is why it is important to have regular checkups with your physician, among other reasons.
Could be a slipping belt. You don't say the make, so difficult to tell. If you know how to access the belt, change it .
Frequency of sound has no impact on the speed of sound (which is ~343 m/s in the air at STP). Consider sound to be waves (as is the correct assumption). When one hears a low frequency sound, fewer sound waves are passing by the listener in a finite period of time than are passing by when a high f…requency sound is heard. Think of the high frequency sound as being "more compressed" rather than "faster." Best of luck! (MORE)
You know how on a piano, middle C sounds like it's in between the low and high notes? Well, that's because it is. The notes below middle C have low pitched sounds just as the higher notes above middle C, become higher pitched. Same goes for the harp. The high notes come from the strings above mid…dle C. They're shorter and thinner so they sound higher and don't resonate as long. (MORE)
One possibility is small hole in the muffler. I had that happen once, and it whistled under accelaration.
Sound is made when air is forced through the vocal chords at the top of the larnyx. The chords sit atop the trachea. When they are constricted, you make a squeeky sound. When they are relaxed, you make a lower pitch sound. This is done subconscienously.
Pitch is determined by vibration frequency. A guitar string vibrating at 440 times a second will product a perfectly tuned "A" note. A string vibrating any faster than this will produce a higher pitch, and any slower will produce a lower pitch.
If you listen to a lot of music of have loud surrounding, the little hairs/nerves in your eardrum can die. The high pitch noise can mean one of those nerves is dying. i listen to a lot of music n my ears buzz sometimes... its so annoying
Yes, on a clear day, if the air quality is crystal clear, and your hearing is incredible. But the folks closer to the actual sound - it's not always pleasant!
Yes. The frequency of the sound determines its pitch. The two are directly correlated. For example, the higher you go on a row of piano keys, the higher the frequency and the higher the pitch. Yes. It is simply understood by the relation that frequency is directly proportional to pitch Yes.
There's no connection between loudness and pitch of a sound. High-pitched sounds and low-pitched sounds can all be either loud or soft.
it depends on how loud the pitch is some pitches are not harmful but they are so high we can hear them i think these type of sounds at a pitch very high are called infrared sound?
High pitch = high frequency = short wave Low pitch = low frequency = long wave
A trombone is a bass instrument, playing in the bass clef, making it a relatively low- pitched instrument..
Whenever there's something vibrating, in the upper range of human hearing, there may be a high pitch sound.
Low pitch = low frequency = long waves. High pitch = high frequency = short waves.
-- the siren on a fire truck, police car, or ambulance -- the fire alarm on any floor in any hotel -- a note in high register, with fermata, played sostenuto and fortissimo by an experienced piccolo player
By definition, matter is required for sound to exist. Sound waves are transferred by vibration of molecules, which is why sound does not exist within the vacuum of space. In space nobody really can hear you scream.
A flute is a small instrument with a small diameter. The smaller the instrument the higher the pitch.
Yes! All sound waves, regardless of pitch move at the same speed provided they are in the same medium. Differences in frequency cause the sound to be perceived as higher or lower. A high pitched sound has a higher frequency and shorter wavelength while low pitched sounds have lower frequencies and …longer wavelengths (MORE)
Current flowing along the wire sets up a magnetic field. Thecurrent in the next wire, in the field of the first wire, causes aforce. The current changes direction, cycling 50 or 60 times persecond, and that is the hum you hear - it's all the wires vibratingslightly.
Vampires, being entirely fictional, are sensitive or not to whatever the author wishes them to be.
The bassoon has a large range, and can play in about 3 octaves. Depending on which part of its range, yes the bassoon can have a high pitched sound
The frequency. Think of it like this. Imagine you two waves like this: __ __ (A) l l__l l__l _ _ (B)l l_l l_l Wave A would be lower than wave B because wave A has a lower frequency, and thus is lower.
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.
Sounds echo when there is nothing else to absorb the sound. So in an empty room, there would only be the walls to absorb the sound, but walls don't absorb sound. They bounce it back. So, when you are in an empty room or a cave, nothing absorbs the sound and it is bounced back. However, if you w…ere to put a couch in the room, it would no longer echo, because the couch soaks up the sound. (MORE)
When you generate a high frequency sound, through earphones or a speaker, you hear it as a high pitched sound. Higher frequency ==> higher pitch. Higher-frequency sounds have shorter wavelengths, and sounds of all frequencies have the same speed, as long as they're all moving through th…e same stuff. (MORE)
There are a lot of uncontrolled variables here. First of all, how loud is the sound? How thick are the walls? Is the door shut? At what frequency is the sound? But generally, people will be able to hear loud sounds in a nearby room.
i dont know why dont you get a life and get off the internet and delete your world of warcraft account
because the minimum distance between the us (the source) and the reflector should be 16.5 cm.
sound is heard louder in empty room because of echo.echo is occurin distance of 17m.if any things or person is inside the room itwill observe the echo and sound is not heard louder.
Yes, t he higher the frequency, the higher the pitch. The lower the frequency, the lower the pitch.
toothed whales (dolphins etc) that echo-locate and bats thats echo-locate. Mice are pretty high pitched but not as high as the echo-locators.
Well sounds, or "velsunda" (archaic Latin: noun, def: youare an illiterate idiot) are an elusive form of noise, and wecurrently don't have the data to determine how they can be heard inbuildings.
I think you mean, "acoustics" as a term meaning how well sounds canbe heard in a particular room or hall.
Low pitched sounds have a low frequency. Higher sounds have highfrequency, that is the number of waves passing a point per secondis greater.
In an empty room, the sound is mostly just bounced around. Whenmore things are placed in the room, they provide more ability toabsorb sound and reflect in different directions such that itactually has to take a longer path to get from one place to another(zig zag instead of straight path) with the c…onsequent attenuationof the intensity of the sound. Mostly though it's the absorption ofthe sound by the stuff you fill the room with. . If a room has things like soft chairs, sofas, beds, etc, they serve to absorb some of the sound waves. (MORE)
