Human voice can determine its growth
A team of specialists in acoustics from Washington University in St. Louis (USA) found a relationship between man and his voice rising. According to the human voice can be easily installed height of the speaker.
As reported by scientists, human growth can not be determined only by special acoustic instruments, but just by ear. Conducted special studies in which volunteers listen to the voice of different people and then determined which of speakers above and those below. The test results showed that students in 62.5% of cases correctly identify human growth without seeing it.
The report’s author John Morton explains this effect is quite simple. He concludes that our larynx creates resonance, as it makes the neck of a glass bottle. You can imagine our vocal apparatus as sealed at one end of the vessel, and then the sound vibrations that catches our ear, are directly dependent on the length of the human larynx, writes dailymail.co.uk.
According to scientists, the higher the growth of human and, therefore, more space in the larynx, the lower tone of voice he speaks. And, of course, on the contrary – the lower growth, the higher the tone of voice.
Work on the definition and recognition of the human voice (the voices rather than speech) has been going on for a long time. Scientists have already had some success in this area, for example on the phone for thirty seconds, you can identify the caller. These technologies greatly interested intelligence agencies and the people working on the creation of special protection of data, but until now the technology determining human growth voice remained unknown.
