Low-frequency sounds are 500 Hz or lower while high-frequency waves are above 2000 Hz . Human ears can register sounds from about 20 Hz in frequency up to 20,000 Hz, depending of course, upon the hearer.
Read moreWhat is the effect of high-frequency current in the body?
At sufficiently high frequencies, most of the current will flow close to the surface of the conductor (being the human body). So there could be thermal effects (burns on the skin) but the most vital organs inside will get much less of a hit . , electronics/electrical engineering.
Read moreWhat is medium frequency currents?
MEDIUM-FREQUENCY alternating currents (MFACs), defined as currents in the frequency range 1 to 10kHz , are used extensively in rehabilitation.
Read moreWhich of the following is the physiological effects of IFT?
As IFT acts primarily on the excitable (nerve) tissues, the strongest effects are likely to be those which are a direct result of such stimulation (i.e. pain relief and muscle stimulation ). The other effects are more likely to be secondary consequences of these.
Read moreWhat are high frequency currents?
an alternating electric current having a frequency of 10,000 or more cycles per second ; it produces no muscular contractions and does not affect the sensory nerves.

Read moreWhat is low frequency therapy?
Low-frequency electrical stimulation (LFES) is an acupuncture technique that replicates the benefits of resistance exercise through stimulation of muscle contraction . In skeletal muscle, insulin or IGF-1 plays critical roles in maintaining protein metabolism.
