This is one for the audio engineers here (the people who truly understand this subject, unlike me). Instead of meaningless descriptions of how switches sound, it may be useful to profile the sounds of keystrokes in different keyboards, and classify them somehow.

For example, not just the peak amplitude of the strongest frequency, but the spread of frequencies, the total amount of sound across all frequencies, and the duration of the sound.

For other readers, here's my rough depiction of what we might be looking at:
For example, I am not sure that anyone actually has ever documented what exactly it is that we are most sensitive to. For a variety of keyboards (e.g. typical scissor switch, Cherry MX Blue, Cherry MX Red (with clack only) Alps SKCM Blue, membrane buckling spring, typical rubber dome over membrane), how does our perception of how loud and how bothersome a keyboard is compare to analysis of the nature of the sound? Can a keyboard sound quieter or less bothersome by putting out the same amount of sound but with a greater frequency spread or a lower range of frequencies?

For me, subjective descriptions of sound bother me more than subjective descriptions of feel.
