160 BPM PULSE
Puppies and kittens have much faster heart rates than humans. Maternal heart rate is approx 120-160 BPM.
Biological Entrainment: The rapid beat feels "normal" to a neonate, whereas slow human music can feel dangerously lethargic or dead to them.
HYDRO-ACOUSTICS
The audio is low-passed to simulate hearing through amniotic fluid.
Comfort Trigger: This specific muffled frequency range triggers the parasympathetic response associated with the safety of the womb/litter pile.
