I know dogs can hear well over 50khz.
I've been searching for a while now for actual examples of things they are able to hear but we can't. There's a lot of generated sounds like this but that's not what I'm looking for.
Can anyone tell or show what kinds of objects or events they can hear? The point is to get an idea of the how the world sounds to a dog. I'm assuming it's a lot busier, but what 'texture' do those other sounds give? By that I don't just mean knowing the pitch, but samples of it. Either pitch shifted so I can hear them (like this song) or in their original format and I'll just shift them myself.
Secondly, is there a way to record such high-pitch sounds with home level equipment? I can afford to spend some money on a better microphone than what's in my headset and/or phone... but obviously it's not going to be professional/research level, nor specialized like a bat recorded.
I should not that i don't necessarily need to get the full range up to 60 or 75 khz, something going up to 40 or even 30khz would make me happy. Just to get a bit of an idea of what lies beyond our human limits, you know?
