Bio-electrical Impedance Analysis or Bioimpedance Analysis (BIA) is a method of assessing your body composition, the measurement of body fat in relation to lean body mass.It is an integral part of a health and nutrition assessment. Research has shown that body composition is directly related to health.io-electrical Impedance Analysis or Bioimpedance Analysis (BIA) is a method of assessing your body composition, the measurement of body fat in relation to lean body mass.
The impedance of a circuit in an amplifier is designed to match the impedance of a speaker or earphone so there is no best impedance, just what the circuit will work best at. Impedance is measured in Ohms just like resistance and that is the similarity. It is the resistance of the circuit to the voltage applied to a device in a pulsating or alternating current. So you buy headphones whose impedance matches the device you are buying the phones for. Source(s):
