I need to study more. This brings up interesting questions for me on ultrasound spectrum and others related to information loss. I hear bass more clearly over distances that are noisy but I hear high pitches over distances without noise. Speakers have filters on them to prevent transmission in particular frequencies. I’m unsure of what quality is related to on mics.

Cool stuff to understand. Thanks. Now I must learn more.

Also, weird: https://en.m.wikipedia.org/wiki/Parametric_array

How do I reason about the range of frequencies that air itself has a threshold of vibration? There’s a particular range within that type of matter itself I’d imagine. Sound is only a human description of a waveform perturbation within the air... I’d imagine if the air vibrates too much it could explode or some other effects.
