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, WikipediaOriginally posted by The article View Post
), 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?Comment

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.Comment

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?Last edited by DWhatley; Oct 19, '10, 9:34pm.Comment

you can check the frequencies of stuff around the house here.

You should also be able to download a program that will output whatever frequency you tell it. I have one on my iphone.

Humm, maybe I will look for a small cheap recording device since we don't have a computer near the tanks.
NOW look what you have started. If they had an octopus I could not resist (and still may not) but I am afraid the talking dolphin would scare them
