Hearing

Pilots need sharp eyes, but Raytheon is looking to their ears as well. The company has developed a new 3D Audio system for aircraft, that turns information into an audible three-dimensional picture. It helps pilots identify where threats are coming from, and keeps radio channels untangled.  Read More

When a child is born with the congenital deformity known as microtia, they have an underdeveloped external ear – also known as the pinna. Even though their inner ear may be normal, the lack of the external structure can affect their hearing, plus it looks unusual. Normally, a replacement pinna is made from a foam-like material (or sometimes even cartilage from the rib cage) and implanted under the skin, although these don’t always look particularly natural. Now, scientists from Cornell University have developed a more realistic pinna grown from biological material, using a 3D printer.  Read More

There is new hope for those of us who have overindulged in loud bands and dread the prospect of old age spent with an ear trumpet clamped to the sides of our heads. Researchers from Massachusetts Eye and Ear and Harvard Medical School have been able to stimulate resident auditory hair cells to become new ones, resulting in partial hearing recovery in mice whose hearing has been damaged by noise trauma.  Read More

Sometimes when you’re cycling, especially if you’re out on the open road, the constant wind noise in your ears can get rather annoying. It can also be potentially dangerous, as it may mask traffic noises. Well, if you’re OK with sporting what at first glance looks like a pair of dark sideburns, Cat-Ears might be the answer.  Read More

A team led by Kazuhiro Nakadai at Honda Research Institute-Japan (HRI-JP) is improving how robots process and understand sound. The robot, aptly called HEARBO (HEARing roBOt), can parse four sounds (including voices) at once, and can tell where the sounds are coming from. The system, called HARK, could allow future robot servants to better understand verbal commands from several meters away.  Read More

Our ears work by converting the vibrations of the eardrum into electrochemical signals that can be interpreted by the brain. The current for those signals is supplied by an ion-filled chamber deep within the inner ear – it’s essentially a natural battery. Scientists are now looking at using that battery to power devices that could be implanted in the ear, without affecting the recipient’s hearing.  Read More

U.S researchers are developing a tiny middle ear "microphone" that could remove the need for any external components on cochlear implants. Led by University of Utah engineer Darrin J. Young, the research team has produced and tested a prototype of the device which uses an accelerometer attached to the tiny bones of the middle ear to detect sound vibration.  Read More

Conventional earphones can become a liability you are out and about on city streets by limiting your ability to hear approaching vehicles or other potential hazards. That’s where the earHero comes into play. It’s an earphone system designed not to block the ear canal so that users are still be able to hear what’s going on around them.  Read More

Last September, scientists from the University of California, Berkeley announced that they had developed a method of visually reconstructing images from peoples' minds, by analyzing their brain activity. Much to the dismay of tinfoil hat-wearers everywhere, researchers from that same institution have now developed a somewhat similar system, that is able to reconstruct words that people have heard spoken to them. Instead of being used to violate our civil rights, however, the technology could instead allow the vocally-disabled to "speak."  Read More
