I can’t imagine that’s pleasant on our canine friend’s ears. You might be thinking, “well what about dog whistles?” But dogs don’t exactly “enjoy” those sounds, especially if they’re used in training (where they’ll have preconceived responses to certain frequencies). High-pitched noises are often troubling and anxiety-inducing to dogs.
There’s no arguing with this point. It’s science. The dot-com boom geeks who wanted you to have all the world’s music for free were clever enough to deploy basic concepts in psychoacoustics, or the study of how the brain interprets sound, in the architecture of the MP3 format. A quick-and-dirty summary of the compression processes at play includes the use of minimum audition thresholds, and simulated masking and bit/sample-rate management via the Nyquist-Shannon Theorem to discard any sonic information that doesn’t contribute meaningfully to a human’s listening experience.
