Pitch lacks a magnitude dimension, complicating its subjective measurement

Evidence

Because pitch is a psychological perception (like loudness), we also cannot measure it directly. Consequently, experiments employ measurement techniques similar to those used for loudness assessment. Matching and rating have historically often been used to quantify pitch. However, as we will see in this chapter, subjective assessments of pitch, particularly those adopting rating techniques, have been much less successful than when those same techniques are applied to loudness. Perhaps this is because pitch is different from loudness, as pitch does not really have a magnitude — a high pitch is not really bigger than a low pitch. Further,more the pitch of sounds contains more dimensions than just “high” or “low.” Rather, sounds have pitch strengths — they can be clear, strong pitches or they can be weak. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 1172
