60 hz frequency effects

How many Hz is safe?
In addition to decibel levels, harmful sound frequencies can also be damaging to human hearing.
Low frequencies (under 20 Hz) and high frequencies (above 20,000 Hz) that humans cannot perceive can also affect the ear and have adverse effects on our health.
What are the benefits of 60 Hz frequency?
The difference in frequency has implications for the design and operation of electrical equipment. 60Hz systems tend to be more efficient for longer distance transmission and are better suited for high-power applications, while 50Hz systems are more suited for low-power, local distribution.
What does 60 Hz do to the body?
However, in some studies, exposure to 50/60 Hz magnetic fields ranging from 20 μT to 200 μT have been found to cause slowing of the heart rate and as well as to change HRV[10, 11, 28]._{24 mai 2013}
A 60Hz electrical system means that the power completes 60 cycles of complete wave sequence per second while 50Hz means that it completes 50 cycles per second. 60Hz is usually associated with 440, 460, 480, & 600 voltages.

Effects of 60 Hz Exposure on Unit Activity of LC The average of LC neurons activity before and after 2 hours exposure to 60 Hz ELF/EMF. These results indicate that short time exposure of both 3Hz and 60Hz ELF/EMFs can suppress LC neurons unit activity significantly immediately after 2 hours exposure (Figure 6).
