Sound at 20-200 Hz is called low-frequency sound , while for sound below 20 Hz the term infrasound is used. The hearing becomes gradually less sensitive for decreasing frequency, but despite the general understanding that infrasound is inaudible, humans can perceive infrasound, if the level is sufficiently high.
Read moreIs 500 Hz high or low-frequency?
Frequency is measured in hertz (Hz) [hurts]. A low- frequency sound is about 500 Hz or lower. A high- frequency sound is about 2,000 Hz and higher.
Read moreWhat low frequency is harmful to humans?
In the past 30 years the concern that daily exposure to extremely low-frequency magnetic fields (ELF-EMF) (1 to 300 Hz ) might be harmful to human health (cancer, neurobehavioral disturbances, etc) has been the object of debate, and has become a public health concern.
Read moreWhat is extremely low frequency used for?
Extremely low frequency (ELF) electromagnetic waves are currently the lowest frequency waves used routinely for wireless communication .15 Nis 2003
Read moreWhat is the effect of extremely low frequency?
The issue of extremely low frequency (ELF) biological effects is very controversial. Research has focused on possible carcinogenic, reproductive, and neurological effects . Other suggested health effects include cardiovascular, brain and behavior, hormonal and immune system changes.
Read moreWhat is extremely low frequency EMF?
Extremely low frequency (ELF) electric and magnetic fields (EMF) occupy the lower part of the electromagnetic spectrum in the frequency range 0-3000 Hz . ELF EMF result from electrically charged particles.
