Foreign object removal from the ear or nose
The range of nasal and aural foreign bodies that present to accident and emergency (A&E) departments, emergency rooms and minor injury units is limited only by the imagination. Aetiology and epidemiology statistics point to patients being predominantly children in the...How to tell if a bone anchored hearing device is working?
Bone anchored hearing aids are becoming increasingly more commonplace with more than 120,000 users worldwide. These devices are based on the principle of direct bone conduction, where sound is transmitted directly through the skull via a titanium implant to the...‘The Sun does not forget a village just because it is too small’ – African proverb
Solar powered hearing aids In the middle of the morning of January 24, 2002, I had been in Otse for only three days, a village of 3500 in the south of Botswana, when I heard a knock at the door....Active middle ear implants and bone-anchored hearing systems
The implantable hearing device market has grown significantly over recent years. But as conventional hearing aids improve and cochlear implant candidacy widens, what is the role for active middle ear implants and bone anchored hearing systems, and how should we...Semi implantable bone conduction devices: challenges and developments
Bone conduction mechanisms and history of bone conduction aids Bone conduction hearing devices work by stimulating hair cells via the bone conduction hearing pathways. These pathways are less well understood than the air conduction pathways, but recent research has shown...Multifrequency tympanometry
There are many good reasons to start using multifrequency tympanometry as opposed to a traditional, single 226Hz probe tone. Here, Leigh Martin of Interacoustics discusses the uses and benefits. Tympanometry is a core test in the audiologist’s test battery. In...Hearables: in-ear sensing devices for recording of physiological signals
Colver Ken Howe Ne, Jameel Muzaffar and Manohar Bance discuss the potential of hearable systems to monitor physiological signals (e.g. from brain or heart, blood pressure, body temperature) unobtrusively. Such adaptations require high-quality sensors and sophisticated de-noising signal processing on...
What Plug?
For decades, audiologists have encouraged people to wear hearing protection when they attend concerts. Traditionally, the most accessible options have been foam plugs, which have limited appeal due to their poor sound quality. Disposable foam plugs absorb high frequency sounds...
