Hearing

For the first time, researchers at the University of New South Wales in Australia have use...

According to the World Health Organization, more than 360 million people worldwide live with disabling hearing loss, and for many, devices such as hearing aids and cochlear implants allow them to maintain a normal life style. But what if a cochlear device could offer a biological solution that would enhance a patient’s experience?  Read More

An online platform where the user can conduct their own hearing test and electronically ca...

According to the Hearing Loss Association of America, 48 million Americans (around 20 percent of the population) report some degree of hearing loss. This problem is compounded by the costs associated with having the condition diagnosed and a hearing aid fitted in a clinic, causing many to allow the ailment to go untreated. iHear, an invisible hearing aid, is designed to significantly lower the cost of personalized hearing devices by enabling the user to test the extent of their condition and calibrate the hearing aid from their own home.  Read More

Wear is designed to help those with hearing difficulties make sense of conversations in no...

From hiding hearing aids in your mouth to having them built-in to the arms of your glasses, we have seen some innovative efforts to assist those with hearing difficulties in recent years. With these unobtrusive technologies available, you might think that wearing a hearing aid around your neck would be the least desirable of options. Yet the team behind Wear believe that by favoring comfort and aesthetics over discretion, it may have conceived a viable alternative.  Read More

BioAid is a free app that allows the iPhone to work as a user-adjustable hearing aid

It’s so obvious when you think about it. The iPhone has a microphone, a computer that can process audio, and earphones – why not use it as hearing aid? That’s just what a group of scientists from the University of Essex have done, with their BioAid app. It has the potential to replace thousand-dollar hearing aids with a free download ... as long as users don’t mind keeping their phone close at hand.  Read More

Raytheon's 3D Audio system presenting a threat warning

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

Researchers have regenerated auditory hair cells in adult mammals for the first time (Imag...

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

Cat-Ears are bicycle helmet attachments that are claimed to reduce wind noise in the cycli...

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

Honda's HEARBO can distinguish between four different types of sound simultaneously

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

An experimental ear-powered chip, with a penny for scale

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
