The foundation of the Phon scale lies in the . These curves represent SPL as a function of frequency for which a listener perceives a constant loudness.
A report on phons and sones, two related units of measurement in the field of acoustics and psychoacoustics. phons and sones
Where:
Measure the loudness level relative to frequency (The "Equality"). The foundation of the Phon scale lies in the
From the formula, we can derive the critical rule of psychoacoustics: An increase of 10 phons corresponds to a doubling of loudness (in sones). phons and sones
– HVAC noise criteria (NC/RC curves) are based on phon-like principles to ensure background noise isn't annoying.
