I was just thinking ... as one does .... if they were all freezing cold, they might ring when you strike them, and supposing you had a nice line-up of varying sizes, you could play a tune on them. Possibly "Tubular Bells". Just a thought.

It's all very well going on about the resonant frequency, but what about the harmonics? What about damping factor? What about ADSR envelopes ?

cnht - I have a big flask of liquid nitrogen, mate. Lets see those oily feathered bastards deal with 77K.

I have been involved with penguin studies for over 30 years and have never noticed them vibrating. In any case if they did vibrate, I would expect them to vibrate at different frequencies depending on size and weight. Is the 0.4m little penguin going to vibrate at the same frequency as the 1.3m emperor?
Why would they want to vibrate anyway?

Obviously would depend on whether these endearing flightless arctic birds were struck, blown or plucked..Based on nothing more than BS, I would say that the primary factor governing resonance would be the lung capacity (a natural air filled cavity). For humans this averages out with an RF of about 42Hz (scarcely audible) and for mice about 325Hz, so the average penguin would tune in about 100Hz. I would estimate the Q (damping) factor to be between 3-5 typical of animal tissue.

Around 650mhz - Although some penguins have been known to resonate at frequencies above 700mhz (although this is very rare)

And how exactly r u going to freeze penguins? Their bodies r made in the manner that they can adapt to the coldest of climates. They do not freeze. At least ask something worthwhile.

I tried to get a penguin in an envelope once - but I couldn't get it through the postbox flap.

Is this a trick question?
In the UK we have a chocolate biscuit wrapped in tin-foil called "Penguin"
Hence the joke:
Why don't elephants like penguins?
Answer: They can't get the tin-foil off.
OK! Suit yourself! Don't laugh! See if I care!

650hz with a Q tune or wave to the mid centre female 660hz with Y tune or wave to the left centre of value of a R

Before i was Butt.I was a Penguin.I can tell you they don't vibrate.

really.. this might be the strangest question i have read.. why would anyone who isnt a penguinologist need to know that??
