Can your “radio” be called that if they listen for sonic pulses ?
I thought the term radio was exclusive to electromagnetic radiation, does the term also apply for sonars ?
Or maybe bats also use some kind of EM waves to echo locate too ?
Edit: not trying to be pendantic, I’m genuinely curious about this
It is a radio though, no? If I tune in to 95.8 Khz to access Capitol FM’s (bad) music, I’m hearing that radio band downshifted to 5-20 KHz on my speakers to make it audible for me.
It’s the same principle I thought for bats, I’m just tuning in to lower frequencies.
Radiowaves are electromagnetic radiation (like visible light and microwaves). Sound waves are kinetic motion between air molecules. Your music radio is receiving electromagnetic waves and converting to sound waves through the radio speakers.
I’m not a biologist or a linguist but I think its perfectly reasonable to call a device that captures inaudible sound a radio. But it is different than your music radio.

pushes glasses up nose well actually,

Huh. Mind blown. I guess that explains why a regular phone with radio capabilities couldn’t pick up the bat calls without an extra device.
I do recall we had to point the “radios” at the source we were trying to capture, so I guess it’s a sonar of sorts?
