There was no evidence of any detrimental effect other than middle ear discomfort. Tests of high-intensity infrasound on animals resulted in measurable changes, such as cell changes and ruptured blood vessel walls. Infrasound is one hypothesized cause of death for the nine Soviet hikers who were found dead at Dyatlov Pass in 1959. [55]
Photovoltaic cell - the first all-sputtered photovoltaic cell for solar energy in 1974. Fiber optics - In 1987 PIRI, a fiber optics venture with Mitsubishi and NTT, was launched, which resulted in a $1.8 billion market. "No-melt" chocolate - In conjunction with Kevin M. Amula, Battelle Geneva developed "No-melt" chocolate in 1988.
The device combined two slightly different frequencies which when heard would be heard as the sum of the two frequencies (ultrasonic) and the difference between the two frequencies (infrasonic) e.g. two directional speakers emitting 16,000 Hz and 16,002 Hz frequencies would produce in the ear two frequencies of 32,002 Hz and 2 Hz.
We found the best technology for adults over 65 at CES this year. From AI aids to ‘aging in place’ smart home solutions, the annual tech show kept older users in mind.
The UK's independent Advisory Group on Non-ionising Radiation (AGNIR) produced a 180-page report on the health effects of human exposure to ultrasound and infrasound in 2010. The UK Health Protection Agency (HPA) published their report, which recommended an exposure limit for the general public to airborne ultrasound sound pressure levels (SPL ...
Infrasound sensitive fibers are found to be simple bipolar cells in the auditory ganglion with a diameter of 1.6-2.2 μm at the axon and 0.9-1.2 μm at the dendrites. [19] They originate in the apical end of the cochlea and they are located near fibers that transmit low frequency sounds in the acoustic range.
By Laila Kearney. NEW YORK (Reuters) - U.S. data-center power demand could nearly triple in the next three years, and consume as much as 12% of the country's electricity, as the industry undergoes ...
