Dogs excel in high-pitched sounds, hearing up to 47,000-65,000 Hz, while humans are limited to 20,000 Hz.
"Dogs excel at detecting high-frequency sounds and hearing extremely soft noises, measured in decibels (dB), including those inaudible to humans."
Dogs hear 3k-12k Hz sounds at -5 to -15 dB, more sensitive than humans. Above 12k Hz, their sensitivity surpasses ours.
Predatory heritage: Dogs excel at high-pitched sounds for hunting. Humans prioritize human voice due to cooperative evolution.
Dogs' sensitivity to high-pitched sounds explains their abilities: predicting earthquakes, anticipating arrivals, and being distressed by loud noises.
Humans hear up to 2,000 Hz, ideal for speech, while dogs hear up to 8,000 Hz, advantageous for hunting. Different ears, different abilities.
Dogs excel in frequency discrimination, detecting minute differences, while humans outperform them in sound localization accuracy.
BAER test determines dog's hearing by measuring brain's electrical activity in response to sounds played through earphones. Quick and painless.
Dogs can lose hearing due to age or ear infection. BAER test helps assess hearing loss. Communication through body language and signals is possible, and high-pitched sounds may still be detected.
