I have two mixed breed dogs, one 75 pounds and the other 65 poundsI am lowering the temperature in the house from 75 degrees to 72 degreesNow I am freezing, so I am wondering if the dogs are tooThey both have very short hair.
The dogs are fineGet yourself a blanket, sweetie.
i don't inevitably think of you may desire to be a senior citizen to understand you may desire to grant some good advice to the sixteen three hundred and sixty 5 days old youi might say to the sixteen three hundred and sixty 5 days old me who had purely began working and can presently by way of be entering into the international of going out to pubs and golf equipment - do not drink too lots and don't be this style of smartarse, yet even though you do do not waste time - you may think of you have constantly yet you rather do not.
I disagree with Xtama Red on this point: Ultra sound (16,000-40,000 Hz) is above the range of human hearing and you wouldn't be hearing itIt also is blocked by normal outer wall insulationThe frequencies you cite (16-16,000) are in the audible rangeNow: The low frequencies (about 16 - 500) easily pass through outer wallsI frequently have a neighbor who drives past with his auto sound system cranked up with a sub woofer turned way up.boom, boom, boom to the beat of the musicIf the levels of noise you are measuring are really there, I agree that you have waited too long to get outSound above 100 dB is harmful to your ears for more than a few seconds100 dB is ear splittingI couldn't stand that for even one minuteI can not even imagine a plausable reason for this kind of a noise (100 dB) coming from a power outlet as well as the Dish wiresWires do not have the ability to emit noise at that level - if they did, you would be able to feel the vibration and see them vibratingI seriously wonder if this simple device is correctly reading the sound levelsRadio shack used to sell a sound Pressure Level (SPL) meterThe way you describe this, one logical (but not reasonable) conclusion is that it appears your home has one of these Tesla coils inside somewhere or right outsideIn addition, if it is that loud, just about anyone should be able to locate the sourceThis has to be something very VERY V E R Y obvious.(if this isn't a troll)
This sounds more like a medical condition than a sonic engineering problemHowever, considering that both of you are hearing the noise it is unlikely that two people simultaneously developed the same medical problemRegardless, a trip to the doctor is a hell of a lot cheaper than a full house insulation, it could be a type of mold which both of you have been exposed to and that's what's causing the audible distubances However, I'm going to assume that the noise you are hearing is legitimateUltrasound is sound which is in excess of 20,000Hz, so a report detailing 16-16000 is not going to show itThe terrible thing about ultrasound is, it goes right through normal insulationThe best thing you can do is reflect it or absorb itThe easiest way to stop ultrasound is using water, the water will absorb ultrasound and it will be converted to molecular vibrations which is then converted to heating of the waterReflection is also possible but not widely used There is another way to stop ultrasound, phase cancellingIt is a technology used in noise cancelling headphones and it may reduce the ultrasound intensity by 50% or moreHowever, in order for this to work you need an exact frequencyIt basically involves a sensor which detects the frequency and then a large piezoelectric speaker which can emit a phase cancelling ultrasonic noise which will cancel out the noise that you are hearing I don't know where the noise is coming from, but it sounds like some sort of magnetron which is malfunctioningCould be a faulty transformer or microwave, maybe a shorted out wire which is sparking and emitting ultrasound noiseEDIT: Ultrasound is audible as long as it is high enough in amplitude and not excessively high in frequency (under 30kHz)However, eventually your ears will be permanently damaged by high amplitude ultrasound and will not be able to hear it anymore, but the health effects may still be present.
