Hi John,

I do not know wether insects are animals for you but 
today I accidently came accross an article dealing with the 
frequency ranges of Tettigoniidae (grashoppers).

Nobu Suga, 1966, Ultrasonic production and its preception in 
some neotropical Tettigoniidae. J Insect Physiology 12: 1039-1050

They produce sound with an intensity of 100 - 110 dB (compare 
that to an airplane) and optimum sensitivity around 25000 Hz 
30 to 40 DB)

If you are more interested in ustrasonic hearing most articles
about hearing in bats should be interesting for you.

God bless you 
JZ
