15 The world's first machine capable of recording the full frequency range of the human ear.
16 The only physical relationship between the chromatic scale and the ear is that both operate on a logarithmic scale in order to accommodate a large frequency range.
17 This method will allow the full-wave analysis of virtually hybrid circuits and get parameters with a wide frequency range through primary simulation.

20 L. F. noise can be better attenuated so as to obtain good attenuation characteristics over the entire audible frequency range by using active noise reduction technique in the closed-air type earmuff.
21 Many existing CO DSL modems may only support a relatively narrow receive frequency range, which will increase the difficulty of estimating the much wider bandwidth far-end loop noise.
22 The discharge is generated by a high voltage power supply with frequency range of 1-20 kHz and effective voltage range of 0-20 kV.
23 This figure shows that the power response is very smooth throughout the whole frequency range, and the controlled off-axis roll off of the tweeter.
