Unshielded consumer electronics like trail cameras sound like a constant whistle to animals with radiated emissions.

Not challenging that by any means but how can what it sounds like to animals be confirmed?
Spectrum analyzer, appropriate receiving antenna, and output hooked to speaker. You can see it as snow on an old tube style television or AM radio. Every animal has a hearing range in Hz and Mhz. Sea going creatures have very low range hearing. Those low range frequencies travel great distances in water. Humans can’t hear it. Same with bats. They have a very high range of hearing over short distances because the sound waves don’t travel very far in the atmosphere. Most mammals fall inside the middle from just below humans to way above.
Think of what could happen when you have a F18 on glideslope (3watts) at say 133.825 Mhz. Someone on board ship turns on an elevator motor at 460 volts and 30 amps. The motor emits noise around 133Hz. As a result the glideslope signal will just get stomped over and not work and the F18 has lost its life.
Thise machines all around us make a lot of noise in a lot of ranges that animals can hear. Old power supplies used to do this in the human hearing range. Remember turning on a device and hearing a very slight low pitch squeal?
