The science

Why Hushimal works the way it does

Each part of Hushimal is based on published research. Here's what the studies looked at and what they found, with links to read each one yourself.

Science-backed sound

Slow, simple, species-appropriate sound

Every animal hears a different slice of the sound spectrum. Hushimal keeps a soft carrier tone inside each species' comfortable hearing band and wraps it in slow, predictable music near a resting heart rate.

Studies in shelters, kennels and clinics have found that calm, slow music is linked with more resting and fewer stress behaviors, while varying the playlist helps prevent animals from tuning it out.

Stories in your voice

A familiar voice carries meaning

Animals that live with us learn the sound of our voices. Research shows dogs process both the words and the tone of human speech, and cats can tell their owner's voice from a stranger's.

Hushimal stories are narrated in a copy of your own voice, so your animal hears a familiar, gentle speaker even when you are busy or away.

Joint bonding activities

Calm touch and shared time

Gentle, consent-led touch such as slow massage, and quiet time together, are linked with calming body chemistry in both animals and people.

Hushimal's guided activities teach owners to let the animal choose, watch for stop signals, and keep sessions short and predictable.

Research findings vary between animals and settings. Hushimal is a wellness tool and does not replace veterinary care. If anxiety is sudden, severe or getting worse, please see your vet.
