I'm wondering how the power behind a sound and the perceived loudness differ, or if they differ??
Somehow it seems like there is some distinction and qualitative difference between a wimpy quiet sound, and a quiet seeming tone with power behind it. But I'm unclear on how this can be, or if it can be in a quantitative sense.
And how does carrying strength of a tone relate to this. It seems as if two tones can have a comparable sense of loudness, but one can have greater power behind it and carry better??
Same question in different guise: If I play back the same recording of a favorite string quartet on two very different quality stereo systems, one very good quality and high power, the other less on both counts, but I play back on both at seemingly equal loudness levels, how will the playback sounds actually differ?
Would love to understand this better.
