Yes, bats hear very well in order to make up for their poor eyesight. The lowest can be 1 kHz for some species and for other species the highest reaches up to 200 kHz. Bats navigate through echolocation.

Ah yes, that is correct, and many have extraordinarily high vocal and aural band-widths of many tens of kHz, but what is their amplitude sensitivity? Their echo-location is limited to at most a couple of tens of metres, and to compensate for low power their maximum call intensity is very high (>100dB re 20µPa for some species) in order to receive useable echoes, but is their hearing especially acute?
