why clap switch is sensitive to sounds?
106251
A clap switch has a transducer which converts the varying pressure in the soundwaves into a tiny electrical signal, and may look exactly like a condenser mic in a cheap tape recorder.  A microchip amplifies the audio signals and a circuit detects a pattern of noises above a certain threshold.  Clapping, or even if a dog barked in the right sequence would cause the detector to throw the switch.  The switch is known as a toggle, since the same action turns it on, then off, in a repeating pattern.

i personally don't have it, but my best friend does....he is applying for disability, but i don't know if it is related to that...my best advice is to use "distraction" music ((he listens to music as much as possible at a moderately low level, y'know just loud enough to be heard personally)) that seems to keep him from becoming too annoyed...other than that he recommends a doctor visit, some other afflictions cause the same symptoms

its beep ... not beef ... and every pc is different ... if it makes more than one quick beep somthing is wrong ... either somthing is not plugged in ryt or needs to have power plugged in or is just bad part ...

The cord should be running from your earphone jack to your line in (ussually blue) of your sound card. If you cant get any sound recorded after you switch the cable gotot VOLUME CONTROL in the task bar, near the taim or START> ALL PROGRAMS > ACCESORIES > ENTERTAINMENT > VOLUME CONTROL.\n\nCheck the Line in volume, if it's muted un mute it. Still no sound then there is something wrong. Mute our mic by the way. Also check your recording volumes in volume control. to do this, in volume control click on the OPTIONS menu and select PROPERTIES. Click the RECORDING radio box, and OK. Put a check mark in the Box marked SLECT, below ANALOG MIX.\n\nRecord in Cool EDIT (or Adobe Audition, that's what it is called now). Should work.

Make sure that you're not running another program that's using any sound. That may be interfering.

Haha... Most living things change their behaviour when exposed to loud music. My dad does all the time.\n\nLoud music plays havoc on the ears, imagine a tiny mouse ear. Plus listening consumes energy... so mice are into some big hell when under such environments.

The answer is probably a yes, but the exact situation will change the answer.\n\nIf you are talking about background noise between the voice phrases you want to hear (Called the Noise Floor), this can be fixed fairly easily if the noise floor isnt too high. What you would do is use a device called an Expander/Gate. A Gate basically mutes (True muting or reducing volume by -60db or more) the audio when the volume goes below a certain level (Basically when you're not talking). If the noise isnt too loud, it will usually be masked by the person talking.\n\nAn Expander is like a more subtle version of a gate. Rather than killing the audio completely, it increases the difference of volume (expands) between loud and soft parts of the audio.\n\nMost video recorders reduce the dynamic range of audio using a proccess called compression. This has the effect of making soft parts of the audio intelligable, while making the loud parts not be over bearing. The problem however, is that this proccess increases the noise floor. I would hazard to guess that this is a major part of the problem you are experiencing if the audio you are using is running through the video recorder.\n\nIf this is the case, a gate will have a hard time functioning because the difference between the loud and soft parts of the audio will be hard for the device to detect (as the difference has been reduced). To compensate, stick an expander before the gate. This will add some dynamic range back to the audio, making it easier for a gate to work. This entirely depends on how much the dynamic range has been compressed... the more it has, the less effective these devices will work.\n\nThe operation of expanders/gates can be tricky. Threshold, attack, release, sidechain/key inputs, and ratio control operation are not immediatly obvious to someone who hasnt used an audio device with these functions on it. However, there happens to be tons of info on the net about these devices.\n\nRegarding using equalizers... they are mostly useful for background hums rather than broadband noise. If the noise sounds like noise (Like a "shhhhh", people talking in the background, wind, etc), EQs will not be very effective. If the sound is more like a buzz or humm or whine (Like an electric motor), then EQ will do very well. Look for a "parateric" EQ when doing this. There are tons of software that has this. Parametric EQs will allow you to not only center on the exact frequency, but the bandwith of the EQ can be set to be very narrow. The more narrow the bandwidth is, the less you effect your original sound. Also, you can kill pretty much all frequencies below 60-80hz (depending on the voice) without have a noticeable impact on the the voice. This will reduce some of the low end rumble in the audio.\n\nIf neither of these options work to satisfaction, one last option is a sampling noise reduction system. Not many programs have this... a free one would be GoldWave (Not very high quality, but still works in moderation). What it does is it takes a sample of the noise floor, notes the frequency response of the noise (called a stamp or print), and then reduces these frequencies from the audio. Used to the extreme, it will produce VERY weird artifacts... used well, this kind of noise reduction is currently the most effective in the world. If you can find software that does this dynamically (doesnt take just one "stamp"), the results can seem like magic.\n\nAll of these options can be attained through hardware, stand alone hardware, or via plugins.\n\nHope that helps.

See this all depends.... if this were in the philosophy section, then it could be debatable.  But alas- it's in the botany section, so yes- it does make a sound.  Friction is created as it falls through the air and hits the ground, and that friction causes soundwaves.  Whether someone is there or not is irrelevant.  Humans can only pick up on a certain range of decibels anyways.  That doesn't mean just because we can't hear it, it doens't make a sound.  It just means that we can't hear it.  People need to get unstuck from themselves and think outside the human box.  "If humans can't.... must not be possible."  Meh.

everyone reacts to different kinds of stress. some are visual, some are auditory. and people can react differently depending on the sound. \n\nthe reaction isn't really conscious. just happens when you hear certain sounds. so it sounds like you're super-sensitive to bells.

Try it. CAUTION - KEEP LIQUIDS AWAY FROM ELECTRICAL CURRENT.\n\nSet up a loudspeaker next to a glass of water (a wine glass is good for this)\n\nWhat do you think will happen when you alter the sound from the speaker?\n\nInvestigate and observe.\nTry a thicker liquid such as milk.

actually there is, but not perfect, it makes the vocal sounds softer...\n\nRealtek's Sound Effect\n\nyou can still hear some vocals but not so loud

You may have developed what's known as hypersensitive hearing. Unless it really bothers you alot, don't worry, it will likely go away. Sometimes medications can cause it, or even some illnesses in various phases. I experience this once in awhile, actually when my medication is not working so well. It's annoying at times, but kind of neat at other times. I've learned to enjoy the cocophony of sounds that I can hear.

When you experience auditory stimulation it is airwaves moving through your ear canals. When you cover up your ears with your palms you are limiting the airwaves going through so they have to squeeze through a small space. It works very much like when you close a window on a car while you're driving down the highway.

Maybe it's muted, or maybe it's not selected for recording!\n\n[Assuming you have Windows]\nOpen Volume Control by double clicking the Speaker icon in the system tray (notification area). (also, Start > [All] Programs > Accessories > Multimedia/Entertainment > Volume Control)\n\nOn the menubar, select Options > Properties.\n\nIn the Properties dialog, select "Recording" under "Adjust volume for", and click OK\n\nNow you should see "Recording Control". Place a tick mark in the check box called "Select" that directly appears below "Microphone". Adjust your mic volume. Too low, nobody can hear anything. Too high, it will squeak!\n\nIf your mic is not performing well even at highest, lower it to the lowest, then go to Options > Advanced Controls. Place a tick mark on the check box named "Mic Boost", "Mic Gain" or something similar. Click OK, and adjust the volume again. (If you don't find Mic Boost, your hardware doesn't support this feature)\n\nNote: It is recommended that you leave the microphone muted in Volume Control, while it is selected for recording in the Recording Control. This ensures that your voice will not be echoed in your speakers.\n\nTo share music that is playing on your computer, select the "Line-In", "CD" or something related directly to the source of the music, instead of the microphone as the recording device.\n_______\nViva La Dvorak! - www.dvzine.org

If a clapper were to come loose from the bell, it goes so fast it can pierce the floor of the bell chamber and fall into the ringing chamber and injure a ringer. All before you can say "Jack Robinson" (there's another question for you...)
