Probably the elephant, which can communicate using very low frequencies.
By recording these signals and speeding up the replay, we can bring them to the audible range.
Otherwise, I'd guess the whales, but I don't have any data.

the lowest frequency Lester was here
The fundamental frequency is the lowest mode of vibration of a system. If you think of a taut string, the lowest mode with which it can vibrate is the one where the centre of the string travels the maximum distance up and down so the string forms a single arc. It is also possible for it to vibrate so that two arcs (one up and one down) fit into the string, and there are many more possibilities with higher frequencies. On a stringed instrument you can hear the fundamental frequency as the normal note which the string plays, and the others as overtones. Other systems exhibit the same phenomenon.
You can't move your hand fast enough, the lowest frequency sound is about 20 cycles per second, if you could move your hand that fast, you might hear sound.
What we currently observe as gamma radiation from nuclear events in stars is something like 10 to 100 exahertz. That's about the upper frequency limit of the electromagnetic radiation we know of, and it will have the shortest wavelength (something at or under 30 nano millimeters). It isn't a stretch to imagine frequencies higher than that, but what is it that can generate electromagnetic oscillations in that range?
bats can hear sounds of higher frequency than humans (supersonic) because they produce them and these sound waves echo back to them by bouncing of items so that they can see how far something is. Just like in submarines. therfore they need to 'hear' these 'supersonic' waves to see.
A Pigeon has the lowest hearing Frequency at .1 Hz.
Assuming you mean the lowest frequency humans can hear, that's about 20 Hz.
A Pigeon has the lowest hearing Frequency at .1 Hz.
20 Hz.
The lowest frequency that the human ear can detect is that of 20Hertz.
The lowest frequency is 10 Hz. A human can hear frequencies from 20 Hz to 20,000 Hz. Some frequencies can be felt rather than heard.
20 Hertz to 20,000 Hertz is the frequency response range that a human can hear. So in answer to your question 20 Hertz would be the lowest pitch a human can hear.
Jack Frost was said to hear low pitch animal noises from miles away so he is the "animal" that can hear the lowest pitch
It varies with individuals of course, but 19-21 is very common
While dogs can hear high frequency sounds, BATS may hold the record. They use high frequency sound for navigation.actually there are 2. dolphins and miceBeluga Whaleand bats
It depends on the type of animal. Dogs can hear a higher frequency than humans, which is the concept behind a dog whistle. Elephants can hear lower sounds than humans.
Radiowaves are the lowest, with microwaves a close second in lowest frequency.
