Extremely low frequency (ELF) fields includes alternating current (AC) fields and other electromagnetic, non-ionizing radiation from 1 Hz to 300 Hz . ELF fields at 60 Hz are produced by power lines, electrical wiring, and electrical equipment.
Read moreIs Extremely Low Frequency dangerous?
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 considered high frequency?
High frequency sound is sound of which the frequency lies between 8 and 20 kHz . High frequency sound with a frequency over 16 kHz can hardly be heard, but it is not completely inaudible. High frequency sound and even ultrasound in the lower frequency zone (up to 24 kHz) can be audible if the sound level is high enough.
Read moreWhat is considered a low frequency?
Anything below 200 Hz is considered low frequency and anything above 2,000 Hz is high frequency sound.
Read moreWhat does low and high frequency mean?
The lower the frequency, the fewer the oscillations . High frequencies produce more oscillations. The units of frequency are called hertz (Hz). Humans with normal hearing can hear sounds between 20 Hz and 20,000 Hz.
Read moreWhat is the difference between high and low frequency waves?
The frequency of a wave is inversely proportional to its wavelength. That means that waves with a high frequency have a short wavelength, while waves with a low frequency have a longer wavelength .
