It may be possible to hear sounds in the future that are currently inaudible. Recent research found that just vibrating the ear bones could create a type of shortcut for sounds to enter the brain. This could boost hearing power.
Divers have enhanced hearing underwater. Scientists aren’t sure why but have speculated that it could be the result of sounds traveling directly through the bones to the brain.
Scientists have found that moths most likely have the best hearing in the world, over and above all species. Their hearing likely evolved over time in order to evade their main predator, the bat.
Humans can hear sounds roughly 50-100 feet away. Alternatively, your dog can hear sounds as far as a quarter-mile (.40 km) away (or more).
