Various studies have shown that 38 to 60 percent of adults with normal hearing have them, although the majority are unaware of these sounds. [33] The people who do hear these sounds typically hear a faint hissing (cicada-like sound), buzzing or ringing, especially if they are otherwise in complete silence. [34]
The hissing of high voltage transmission lines is due to corona discharge, not magnetism. The phenomenon is also called audible magnetic noise, [1] electromagnetic acoustic noise, lamination vibration [2] or electromagnetically induced acoustic noise, [3] or more rarely, electrical noise, [4] or "coil noise
A leak noise correlator is an electronic device used for Leak Detection and as a leak locator to find leaks in pressurized water or gas lines.. Typically, microphones or acoustic sound sensors are placed in contact with the pipe, at two or more points, to record the sound emitted by a leak (e.g. a hissing noise) somewhere between the points.
The dry air produced by heating systems can irritate your nasal passages and throat, which can in turn cause discomfort, Lizarzaburu adds. Dry air can also make it harder to fight off colds.
The microwave auditory effect, also known as the microwave hearing effect or the Frey effect, consists of the human perception of sounds induced by pulsed or modulated radio frequencies. The perceived sounds are generated directly inside the human head without the need of any receiving electronic device.
Hiss or Hissing may refer to: Hiss (electromagnetic), a wave generated in the plasma of the Earth's ionosphere or magnetosphere; Hiss (surname) Hissing, a Korean manhwa series by Kang EunYoung; Noise (electronics) or electronic circuit hiss, white noise present at low level in all electronic circuits
Bubbles of cool water vapor form and collapse at the restriction, causing the familiar hissing sound. At very low flow settings, the viscosity of the water becomes important and the pressure drop (and hissing noise) vanish; at full flow settings, parasitic drag in the pipes becomes important and the water again becomes silent.
The other Gallican rites are largely devoid of sufflation, though the so-called Missale Gothicum contains a triple exsufflation of baptismal water, [22] and a prebaptismal insufflation of catechumens is found in the hybrid Bobbio Missal [23] and the 10th-century Fulda sacramentary, alongside the more common baptismal exsufflation.
