Can radio waves cause vertigo?

Some people complain of headaches, fatigue, dizziness or concentration difficulties, symptoms which have been suggested to be triggered by exposure to radio frequency (RF) fields. Such complaints have raised concern that certain individuals may be more sensitive than others to electromagnetic energy.

At what range of frequency is the human ear sensitive to sound waves?

2000 – 5000 Hz
While 20 to 20,000Hz forms the absolute borders of the human hearing range, our hearing is most sensitive in the 2000 – 5000 Hz frequency range. As far as loudness is concerned, humans can typically hear starting at 0 dB.

Can humans hear radio frequencies?

Yes, humans, under special circumstances, can hear radio-frequency pulses in the range of 2.4MHz to 10GHz (corresponding to radio frequencies and microwave) as buzzes, clocks, hiss or knocking at apparent auditory frequencies of 5kHz and higher (very high-pitched).

What sound frequencies can a human ear detect?

Frequencies perceived by man and some common mammals Human ear perceives frequencies between 20 Hz (lowest pitch) to 20 kHz (highest pitch).

What sound frequency can a human ear not detect?

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.

What are the effects of radio frequency?

RF radiation has lower energy than some other types of non-ionizing radiation, like visible light and infrared, but it has higher energy than extremely low-frequency (ELF) radiation. If RF radiation is absorbed by the body in large enough amounts, it can produce heat. This can lead to burns and body tissue damage.

How do radio waves turn into sound waves?

Radio waves have the longest wavelengths in the electromagnetic spectrum. You can tune a radio to a specific wavelength—or frequency—and listen to your favorite music. The radio “receives” these electromagnetic radio waves and converts them to mechanical vibrations in the speaker to create the sound waves you can hear.

What limits the range of human hearing?

The human auditory field (green) is limited by the threshold curve (bottom) and a curve giving the upper limit of sound perception (top). At each frequency, between 20 Hz and 20 kHz, the threshold of our sensitivity is different. The best threshold (at around 2 kHz) is close to 0 dB.

Can we hear radio waves in the human ear?

Well, yes, but not really. Radio waves have frequencies ranging from 3 kHz to 300 GHz. The human ear can generally hear sounds with frequencies between 20 Hz and 20 kHz. So technically there’s an overlap. Although VLF, ULF (ultra), SLF (super) and ELF (extremely low frequency) qualify as “radio waves” by spectrum,…

What frequency is too low for human hearing?

Low frequency sounds can be harmful Human beings are normally able to detect sounds in the range of 20-20,000 Hz and it is well known that sounds within this range can damage the hearing. However, sounds under the frequency of 20 Hz can also affect the ear even though we are unable to hear them.

Is it possible to hear radio frequencies?

Hearing radio frequencies. Indeed, one can record electrical potentials inside the cochlea evoked by RF pulses that look just like potentials evoked by sound waves. The authors further report that the apparent acoustic frequency of the RF pulse is independent of the EM frequency of the actual pulse but dependent upon head dimensions.

Are low frequency sounds harmful to the human body?

Low frequency sounds can be harmful. Human beings are normally able to detect sounds in the range of 20-20,000 Hz and it is well known that sounds within this range can damage the hearing. However, sounds under the frequency of 20 Hz can also affect the ear even though we are unable to hear them.
