Pets: The Science-Based Guide to Sound

Dogs hear to ~45,000 Hz and cats to ~64,000 Hz — your "quiet" home may be full of sound only they can hear.

Pets live in a different sound world. Because their hearing extends far above ours, electronics, LED drivers and pest repellers can be an invisible source of stress. This is the lowest-competition, highest-loyalty niche in the whole ecosystem, with genuinely surprising science.

The evidence differs by species. For dogs, human music works — shelter studies found classical, reggae and soft rock reduced barking, pacing, heart rate and cortisol, while heavy metal increased agitation. Crucially, dogs habituate, so a single looped track loses effect — playlists must be varied. For cats, human music barely registers; music composed for cats (feline vocal range, purr-based tempo) is far more effective.

Timing matters more than the track: introduce music while the pet is calm so it becomes a safety signal, not an alarm. And nearly 1 in 4 dogs fear loud noises — making fireworks season (Lunar New Year and New Year's Eve in Vietnam) the highest-value seasonal content of the year.

How to use this guide

  • Keep volume lower than feels right to you — their ears are far more sensitive.
  • Use long (8–12 hour) varied playlists to cover the owner's absence, and prevent auto-play from switching to unsuitable audio.
  • Music supports; it never replaces a veterinarian. For firework desensitization, follow the gradual process exactly — doing it wrong makes the fear worse.
