    Squid studies shed light on hearing mechanisms in humans
    From ScienceDaily.com:

    The ordinary squid, Loligo pealii -- best known until now as a kind of floating buffet for just about any fish in the sea -- may be on the verge of becoming a scientific superstar, providing clues about the origin and evolution of the sense of hearing.

    However, up to 500Hz apparently covers most of the range used by baleen whales (thank you, Wikipedia :oops:), which could be very useful. (BTW, isn't Loligo now Doryteuthis? Tsk, tsk.)

    I have been trying to find out what commonly available things make noises at their hearing range. It would be interesting to create a "dinner bell" if I could find something appropriate. Anyone with a clue?

    A loud clicking noises, I always hear them when I'm diving.....Like the sound made by those antique tin alligators that clicked. I have thought would make a good 'dinner bell', loud repetitive clicking.

    Or as a kid we used to bend the lids from glass Snapple bottles and they would click really loud. That woudl be perfect too.

    I have found several dog clickers and toy clickers and I may order one but first I want to find something that I know is within the 400-1000 hz range noted in the octopus hearing article last year. Since this article mentions 500hz I am using that frequency to search. So far I have found that the low note on a car horn is in this range but I am still looking for something practical.

    I found one project buzzer with a 300-500hz range but how would I know (without buying test equipment) what the actual output is?

    this paper is fantastic. An incredible amount of high-precision work to do those experiments...
