Recorded Ramsey RB1 rat chaser box with an Earthworks TC 30 omnidirectional mic placed 2.5 feet from the feedhorn. Freq analysis shows spikes above 20 kHz. My ancient ears can't hear it.

  Looking at it though, I'm probably only hearing the 11-12k range.

  Wow! I can hear it at 43, volume at 10 o'clock, good speakers. I'm very surprised, 'cause I've really abused my ears - or so I thought. Cheers and good sound. Was actually looking for real rat sounds, but this is useful :)

  I can hear it just fine at 24. That would chase me out of the house as well!
