SPCA_Fireworks_Poster_Cat “Animals are a beautiful part of creation.  They are dependent on our kindly and Compassion for their well-being.  As we move forward in the new South Africa, Let us never forget that our animals are part of our society and that we, as Responsible people, are duty-bound to take care of them in the best possible way”.

- Derek Hanekom, Minister of Land Affairs and Agriculture, SA 1996 (foreword to Heroes & Lionhearts).

Cats and dogs are able to hear a wider range of sounds, and softer sounds than humans.

The pitch of a sound is measured in Hertz (Hz), and the comparative hearing ranges of dogs, cats and humans are the following:

Humans:   20 Hz – 23 Hz
Dogs:        45 Hz – 60 Hz
Cats :        45 Hz to 64 Hz

To give you a practical example of this 64 Hz (roughly the lowest note a dog can hear) is the pitch of the lowest key on a piano.  For every doubling in Hz, the pitch goes up an octave.  Cats with the top of the range of 64 Hz vs 23 Hz in human, can thus hear sounds at least two and a half octaves higher than humans can.  This is why dogs and cats respond to dog whistles.  The sound is too high for us to hear, but still within their hearing range.

Dogs can hear 5 times more accurately than humans.  This also explains why dogs and cats are so scared by the sound of fireworks, which to us, do not seem so loud.  They are in fact at least 5 times louder to our pets!
