Flat weighting

In a noise-measuring set, flat weighting is a noise weighting based on an amplitude-frequency characteristic that is flat over a frequency range that must be stated.

Notes

Note 1: Flat noise power is expressed in dBrn (f₁ − f₂) or in dBm (f₁ − f₂).
Note 2: "3 kHz flat weighting" and "15 kHz flat weighting" are based on amplitude-frequency characteristics that are flat between 30 Hz and the frequency indicated.

gollark: I don't know why nobody else thought of this.

gollark: My upcoming licensing system simply does not implement `Copy` or `Clone` on the programs.

gollark: Actually, PotatOS's OmniDisk™ licensing system is flawless, optimal and good.
