Animals vs. Humans—How Do Our Hearing Levels Stack Up?

Tuesday, September 6, 2016 9:00:49 AM Australia/Melbourne

Animals vs. Humans—How Do Our Hearing Levels Stack Up?The animal kingdom is a magical one. It doesn’t matter if we’re talking about our furry, four-legged friends, or those in the reptile arena, they are surprising us over and over again. More and more science continues to emerge on how their brains and beings work. A lot of it will blow your mind. While the studies in general amaze us, today we focus heavily on their hearing levels. Who wins? Spoiler—the animals win this one. Read on for more interesting facts that we’ve unearthed.

 

  1. Wondering where humans stack up in the hearing scale? We show up a lot lower than you may think. In a recently polled group, ordered from the strongest and most specifically targeted hearing, the order went- porpoise, beluga whale, bat, mouse, cat, dog, rabbit, cow, horse, sheep, human, elephant, owl, goldfish, chicken and rounded up with tuna as the lowest hearing levels. Surprised? We’ve got even more shockers for you below.
  2. Not every mammal uses their ears for their hearing. In fact, many don’t. Take dolphins and porpoises for example. Even though they have physical (albeit small) ear openings on their heads, they actually use their lower jaw bones to hear.
  3. About to complain about the hearing levels of your human significant other? Bats put us to shame. They use echolocation, which is a system of soundwaves. The soundwaves radiate from either their nose or their mouths. They’re so powerful that they can pick up insects as small as gnats.
  4. You know how it feels to be fully submerged in water? The further down you swim, the less you see the sunlight from the surface? It gets pretty dark under the sea. Beluga whales spend so much time submerged with so little light, that their hearing becomes their predominant sense. They can’t rely on their sense of sight, so their hearing is very much heightened.
  5. A lot of species have arcs in the development of their hearing. Mice peak at 30 days. That’s when their hearing is the strongest. The next 20 days breeze by and at day 50, their hearing begins to drastically degrade. A group of scientists found that at only 20 months, mice have significantly lower levels of hearing.
  6. There is a strong correlation between location and understanding of hearing. Did you know that humans can identify a noise within five degrees of its location? The same cannot be said for cows. Cows have a much harder time pinpointing the source of the noises that they hear. They can only narrow it down to a 30-degree sphere. So don’t feel too bad the next time a cow appears to ignore you.
  7. You’ve read a lot about the cochlear hairs found in humans. They play an important role in our hearing systems. Unlike us, chicken can regrow these hair cells in their inner ears. This means that as they age, their hearing actually does not deteriorate, making them a great subject of study for much research.
