About five weeks ago Matthew Cobb posted an item here about Smokey, a British cat reputed to have the world’s loudest purr. Well, it’s just now been made official: the Guinness Book of World Records has recorded Smokey at an astounding 67.7 decibels, making her the holder of the title for Loudest Purr by a Domestic Cat. That noise, sixteen times louder than the average purr, is roughly equivalent to the sound of a vacuum cleaner, right at the threshold of “annoying loudness.”
How loud is Smokey? Have a listen:
A funny MSNBC piece, including an interview with both Smokey and her owner, is here.
The Guinness site helpfully compares this to other animal sounds:
The loudest animal sound is the low-frequency pulses made by blue whales (Balaenoptera musculus) and fin whales (B. physalus) when communicating with each other. These whales reach an amazing 188 dB on the decibel scale, creating the loudest sounds emitted by any living source. Total silence is 0 dB, a lawnmower – 90 dB, car horn – 110 dB, – a rock concert — 120 dB. Blue whales and fin whales are louder than all of these!
