The frequency grid has it advantages allowing a human to hear listen to voices up to a frequency of 22 kHz. Other living creatures have different hearing frequncies and may be even higher. It's possible to place a voice of human in the normal hearing range, but is it possible to clock and mask it as in stealth? This is possible if it's out of the hearing range of humans, but brought back into the hearing range again by a decoder, or a a system to lower the frequency to a human frequency? Is this a possible thing to be done, that a human can listen to something out of human frequency range and even manipulate the sound to another frequency in order to be heard? This would result in disaster as the sound would be out of tune and unable to be understood. This is not possible and only in human sound range can a human voice be heard. Careful consideration has to be made to what is being heard and what is in stealth mode or in simple terms, what is not heard, even though the person who is talking in front of you, he may be talking to others in stealth as well. The reason is clear now, there could be a very tempting business deal but in stealth, your head could be removed and a hound of hell in your place or a piramid dog walking on 2 legs in your place when the business deal is done. Please be careful, terrorism is real and the threat of terror from failed religions are real, as the failed religion belivers are trying everything to reinstate themselves. I believe that my wife's miscarriages are due to my status as United States General and a supporter of the United States war effort, anti terrorrism and anti Al-Qaeda. The miscarriages of my unborn children are fraud and my unborn children have been murdered in Singapore by terrorists. Thank you. Written by Junt Hoong Chan MIET MIEEE CEng.
