Definitions of ‘Loudness’ and ‘Pitch’ suggest an unasserted subclass relation

[gregfowlerphd]

The definitions here read as follows:

Loudness: A Sound Process Profile that is characterized by the amplitude, frequency and power of translated sound waves, typically on a continuum from soft to loud.

Pitch: A Sound Process Profile that is characterized by the frequency of translated sound waves, typically on a continuum from low to high.

Given the first definition, every instance of loudness is a sound process profile that is characterized by the amplitude, frequency and power of translated sound waves. Hence, every instance of loudness is a sound process profile that is characterized by the frequency of translated sound waves and is thus (according to the second definition) an instance of pitch, making loudness a subclass of pitch.

I take it that this unasserted subclass relation is unintended and incorrect. Might it be avoided by adding ‘entirely’ before ‘by’ in the second definition?

Great observation. I don't think we want Loudness to be a sub of Pitch. I think it's Loudness that is wrong.

Loudness: A Sound Process Profile that is characterized by the amplitude and total energy of translated sound waves, typically on a continuum from soft to loud.

Thanks, Mark. :) I just wish I hadn't assumed CCO had the basics right, so that I would have looked into the phenomena more like you did.
