Bioelectrical impedance analysis (BIA) is a commonly used method for estimating body composition, and in particular body fat.ince the advent of the first commercially available devices in the mid-1980s the method has become popular owing to its ease of use, portability of the equipment and its relatively low cost compared to some of the other methods of body composition analysis.
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):
