Equal Temperament Audio Frequency Spectrum Chart/Table of Notes in Hertz (For The Entire Audible Range of Human Hearing)
At the time that this is being posted, there appeared to be no chart, table or spreadsheet available on the Internet which showed all of the notes for the full range of human hearing.
The 12-TET Equal Temperament is a musical system of tuning. In this system, the same ratio exists between each of 12 semitones.
The chart/table below shows each of the Helmholtz musical notes (A-G) in Hertz for the entire range of human hearing, as well as below and above this range.
If you would like the table below in Excel format (with the 12-TET calculation of absolute frequencies derived by an embedded and copyable formula), then click here to download.
