There comes a time when we (partly) lose our hearing. Age often plays a role, but exposure to loud noises, head injuries, infections and even the use of certain medications can cause us to hear less well. This is a blessing for a number of people, because it prevents you from picking up a lot of whistling, but most people are very attached to their hearing and experience hearing loss as a big mess.
Fortunately, there are organizations like Better Hearing that develop resources to (partly) regain our hearing. They develop hearing aids that are becoming more sophisticated. In order to keep coming to the ice as possible, hearing scientists are increasingly looking at organisms other than humans, to better understand the principle of hearing.
We find a very interesting animal to watch at the Leijpark. It's a small green sabre grasshopper named Southern shrew. You wouldn't say it when you look at him like that, but the animal does have ears. They are many times smaller than human ears and are not at the head, like we do. The Southern pointer head has ears in its knees!
For a grasshopper, it is vital that he has excellent hearing. If you know the names of a number of grasshoppers sitting next to him in the grass, you'll see why: In the vicinity of a grasshopper, the crasser, buzzer, alarm clock and rattle, and all those beasts make sound. It's a cacophony of the best in the low struwel. Between all that buzzing, rattling, scratch and rattling, the Southern pointer head needs to be able to filter out the ultrasonic sound of the bat, so as not to end up at #1 on the menu right away. So good ears are vital.
Scientific research has shown that locusts have ears (in function) similar to our ears. We have ossicles and a tympanic membrane that already interact with electrical vibrations to the brain, which is perceived as sound. And warm temple: the grasshopper also has such an ear. We are already ready to control a robot using sound, by linking the ear of a grasshopper to the robot. Imagine what progress this is.! A robot is replaceable, a lifetime not. A robot can be sent to an explosive to dismantle it and you just need to clap in your hands to control it.
For people with hearing damage, it's good news too. By looking at the grasshopper's ear, we can create much more advanced hearing aids that are much smaller than current hearing aids. Grasshoppers are easy to grow, so we don't have to threaten animal species.
You know, nature offers us so much more than beautiful pictures and wonderful sounds when we pay attention. We sometimes see a natural people in the jungle on television that makes full use of natural resources, and then we say to each other that “we lost that”. Scientifically, that's not true. On the contrary, science is increasingly focusing on nature. Why invent the wheel yourself if that's been done long before us?. It's time to start observing, good observation. Southern pointed head paves the road. The knowledge is there, the possibilities too. It's just a matter of pointing ears.
