Project Title: “Optimizing hearing with top-down brain control of the ear.”
The overall goal of my research is to understand how auditory input from the ear affects the brain, and how the brain in turn affects the ear through efferent feedback loops. I am particularly interested in understanding the hearing disorders that develop when input to and from the brain is altered. We propose to study top-down efferent effects on hearing to understand how the brain controls the ear using optogenetic, behavioral, and immunohistochemical techniques in rodent models. Understanding how these pathways work may open up new treatment avenues for hearing disorders and will help us understand how hearing is optimized by top-down brain control of cochlear activity.

Project Title: "A Novel Micro-probe for Direct Stimulation of Cochlear Hair Cells
The ear is the fastest and most sensitive sensory organ in the human body. It can resolve data a thousand times faster than the eye and can detect vibrations in the environment at the atomic-scale. The dynamic range of human hearing embraces up to 120 dB of sound-pressure level (SPL). This dynamic range allows humans to hear a millionfold range of amplitudes. The frequency response of a human ear extends to 20 kHz while other mammals, such as whales and bats, can hear up to hundreds of kilohertz. However, the current stimulation probes of hair cells in the cochlea, the sense organ of the ear, to study the mechanics of the inner ear is limited to less than 1 kHz. This limitation leaves most of the mammalian auditory frequencies unstudied. This experimental limitation is due to the physical dimensions of the probes and their configurations used during experiments. My work is design and construction of a micrometer scale novel probe that will overcome the current frequency limitation.

When Sound and Touch Collide: A Little Synesthesia Exists in All of Us
Everyone knows the feeling - the chills when you hear that one song, or the painful shivering at the sound of nails against a chalkboard. Now, imagine if your body continuously heard sound through its skin.
Sherrilyn Roush is the first reported individual to have developed this form of synesthesia, a neurological mix-up of senses, after a stroke that left her numb in the left side of her body. Researcher Tony Ro was lucky enough to study her incredible anomaly, and his theoretical findings are monumental. He believes sense of hearing may have evolved from a sense of feeling, and that Roush’s merging of sound and touch is just an exaggerated version of what happens in all of our brains. Although speculative, it’s possible that what scientists now interpret as a merger of sound and touch might actually be a reflection of an earlier state in which the two senses were one.

Why Some Cultures Don't 'Mind' Auditory Hallucinations
An auditory hallucination is a form of hallucination that involves perceiving sounds without auditory stimulus.
Although an alluding stigma of mental disorders may cause you to think that auditory hallucinations rarely stray from harsh and threatening, 'voice-hearing' can be quite the contrary.
A new study suggests that
schizophrenic people in more collectivist societies sometimes think their auditory hallucinations are helpful. Stanford anthropologist Tanya Luhrmann found that voice-hearing experiences of people with serious psychotic disorders are shaped by local culture – in the United States, the voices are harsh and threatening; in Africa and India, they are more benign and playful. This may have clinical implications for how to treat people with schizophrenia, she suggests.
The Distorition of Sound
81 years young with 27 Grammys
under his belt, Quincy Jones is the
musical titan of the 20th century. But what does he have to say about music of the 21st century?
Harman Kardon's new documentary, The Distortion of Sound, ventures into the complex pros and cons of music of the digital age. Whilst the documentary contends a generation of music lovers being 'raised on low-grade sonic sludge', Jones' has a new dedication to soul and sound, which is making certain that music shall be heard and enjoyed in the way that its creators intend.

NHS Accused of ‘Cruel’ Rationing of Hearing Aids
Campaigners are accusing the NHS of imposing “cruel” cuts on people who are going deaf by denying them the hearing aids they need.
Due to financial challenges, growing numbers of NHS organizations are planning to ration access to the devices, even though they help to combat dementia, depression and social isolation among the hard of hearing.
“To deny somebody the right to a good quality of life – the opportunity to be an active member of the community, interact with family and friends, or even to continue working – is akin to saying to someone, ‘I can make your life better by giving you hearing aids but I’m not going to’. It’s wrong, it’s cruel,” said Louise Hart, of Action on Hearing Loss.

Project Title: “Optimizing delivery of drugs to the middle ear without tympanostomy”
Over the years, my research has focused on the sense of hearing, in sickness and in health. In particular, after developing a rat model of noise-induced tinnitus, I was struck by the lack of methods to deliver drugs to the ear only, bypassing the severe side-effects of most (for instance, oral) treatments. Over the last several years, we have developed a magnetically assisted drug delivery method using biocompatible drug-eluting nanoparticles which allows us to deliver therapeutic drug levels in the cochlea only. More recently, we realized that this method could be used to deliver antibiotics and other drugs from the ear canal to the middle ear, without the need for tympanostomy tubes.
Our long-term goal is to improve and transform the treatment of ear infections by delivering medications into the middle ear with nanoparticles magnetically pushed through the tympanic membrane which remains intact. Ear infections are the leading cause of visits to pediatricians. In the US, there are ~15 million cases/yr of acute ear infections in children less than 5 years of age. About 20% of these children will progress to chronic ear infections with effusion of fluids in the middle ear. Tympanostomy tube placement under general anesthesia for the treatment of recurrent or chronic ear infections is the most common pediatric surgery requiring anesthesia in the US. This crucial Capita foundation grant will allow us to obtain the preliminary data necessary to establish the validity of the method and some optimal parameters for maximal drug delivery.

Ohio State University Eye and Ear Institute Project Title: “Cochlear Hair Cell Regeneration using Adipose Stem Cells in NIHL.” This research seeks to use a novel source of stem cells, adipose-derived stem cells, to regenerate lost cochlear hair cells in an attempt to improve hearing in a chinchilla model of noise-induced hearing loss.
Novel hearing aids lead to bionic future of disability devices
Two brand new models of advanced hearing aids can be adjusted with exquisite precision through software built into Apple’s iPhone. They NOW allow fine-grain control over acoustic systems. “This state-of-the-art technology will give people with hearing loss the ability to outperform their normal-hearing counterparts,” said Dave Fabry, a Starkey vice president, whose company along with GN ReSound Linx developed this technology, each independently. Researchers from both Starkey and GN ReSound used the iPhone as a way to correct problems that had forever hampered hearing aids using a low-power version of Bluetooth wireless technology. The phone could act as a remote control, a brain, and an auxiliary microphone and it would finally let people make phone calls and listen to music without carrying a wireless device.
“I’m surprised they haven’t done this earlier — putting it all in an app, that seems so obvious these days,” said Todd Chamberlain, a 39 year-old industrial safety officer who has worn hearing aids since he was 3 years old.original New York Times article

Infant Sleep Machines at Maximum Volume Reported as Hearing Risk
Sound devices used to lull infants to sleep can be loud enough at maximum volume to damage their hearing, researchers reported Monday.
Researchers at the University of Toronto evaluated 14 popular sleep machines at maximum volume and found they produced between 68.8 to 92.9 decibels at 30 centimeters, about the distance one might be placed from an infant’s head. Three exceeded 85 decibels, the workplace safety limit for adults on an eight-hour shift for accumulated exposure (NIOSH). At 100 centimeters, all the machines tested were louder than the 50-decibel limit averaged over an hour set for hospital nurseries in 1999 by an expert panel concerned with improving newborn sleep and their speech intelligibility.
“Farther away is less dangerous, a lower volume is better and shorter durations of time, all things that deliver less sound pressure to the baby,” Dr. Papsin said. Yet some models are designed to be affixed to the crib.
A concern is whether listening to white noise can be detrimental to auditory development. A 2003 study (Science) found continuous white noise delayed development of the brain’s hearing center in newborn rats. In humans, the brain of a newborn is learning to differentiate sounds at different pitches even during sleep, said Lisa L. Hunter, scientific director of research in the division of audiology at Cincinnati Children’s Hospital. “If you’ve conditioned them to white noise...they might not be as responsive as they otherwise should be to soft speech,” she said.
