A person recently asked me what I meant by the term business system.. I thought others might like to know a definition that works for me. A system is a procedure, process, method, or course of action designed to achieve a specific result.
The voiced speech of a typical adult male will have a fundamental frequency from 85 to 180 Hz, and that of a typical adult female from 165 to 255 Hz. Thus, the fundamental frequency of most speech falls below the bottom of the voice frequency band as defined above.
A speakerâs maximum and minimum frequency ranges are measured in hertz to kilohertz, with the low frequencies for car speakers ranging from 20 to 2,000 hertz (Hz), and the high frequencies from 8 to 22 kilohertz (kHz), or 8,000 to 20,000 Hz.
