Amphibian sound sensitivity?

[Bulb]

Hi all, I am an avid fan of all things amphibian, and i've have done considerable research on forums, informational websites, ect. yet there is one question that has gone unanswered. So to my question to you all:

How sensitive are amphibians ( in particular large toads and frogs) to sound?

I Have a couple of terrariums in school that i've tinkered with, but have neer had one at home. I have a pretty decent speaker system in my room and can cranck the sound up pretty high at times. If i'm to have a terrarium in my room i will take it easier on the volume knob, but i'm still concerned. The last thing i want is an ill treated, traumatised toad of which i am to blame. Any words of wisdom are greatly appreciated.

Most frogs and toads are only sensitive to the sounds of others of their kind (calls and such). A lot of frogs can't hear the radio/TV because it has a different frequency than what the frogs can hear. Some frogs are more sensitive than others though, is there a specific species that you wanted to get?
Also it depends on just how high you turn the volume up. If you turn it up to where the whole room vibrates, then yeah I wouldn't keep frogs in there. I've had Fire Bellied Toads in my room right next to a TV and they have never shown any signs of being agitated by the noise, but I also don't turn it up very loud.
