| One option that might be worth investigating is, rather than trying to hear the high-pitched calls, use an app that will create a real-time spectrogram so you can “see” the calls. I did a quick search and found this article that lists a few apps that appear to do this:
I haven’t tried any of them myself, but since I suffer from high-frequency hearing loss and my hearing aids can only help so much, I may give one or more of them a try.

I have dipped on sighting the Striated Grass-wren and the Mallee Emu-wren on each of my last three trips to Hattah-Kulkyne NP. I use the approach to finding these birds suggested by Rohan Clarke and Tim Dolby, “walk slowly and quietly while listening for their high-pitched calls.” I have spent days trawling through ideal mallee spinifex habitat and heard not a squeak - deafening silence. I would say my hearing is in the normal range for someone my age - 67.
Is there a readily affordable microphone that can pick up the high frequency calls and ‘convert’ them into something I can hear? I imagine that people interested in bats face a similar problem and are able to access equipment that enables them to hear their calls.
