1 This is one of the harder things to get right in a system because it infers strong requirements gathering and strong design that correctly interprets the requirements. 2  This is where good System Architects, Business Analysts and Project Managers earn their keep.
The Mid Range The Mid Range band of frequencies covers two octaves from 500 Hz to 2 kHz. This range can give a horn-like quality to instruments (500 Hz to 1 kHz) and a tinny sound (1 kHz to 2 kHz) or a telephone-like quality (all of the range). Equalization usually centers around 800 Hz and 1,.5 kHz.overing about 1.5 octaves, from 80 Hz to 250 Hz, this range of frequencies determines the fatness and fullness of the instrument's sound. Equalization is usually applied centered around two frequencies, 100 Hz and 200 Hz. For guitars and bass, the 100 Hz range tends to add body and fullness.
Normal human hearing ranges from 20 hertz to 20,000 hertz. Low-frequency sounds, below 20 hertz, are referred to as âinfrasoundâ and travel farther than high-frequency sounds. Frequencies above the range of human hearing (20,000 hertz) are referred to as âultrasonic.â.lthough the upper end of human hearing is about 20,000 hertz, deer can hear frequencies to at least 30,000 hertz. But, these high-frequency sounds must be louder because high-frequency sounds donât travel as far as low-frequency sounds. Hearing and Vocal Communication.
