A wearable electroencephalogram (EEG) device for continuous monitoring of patients suffering from epilepsy would provide valuable information for the management of the disease. Currently no EEG setup is small and unobtrusive enough to be used in daily life. Recording behind the ear could prove to be a solution to a wearable EEG setup. This article examines the feasibility of recording epileptic...

Many children have benefited from cochlear implant device including those with congenital malformation of the inner ear. The results reported in children with malformed cochlea are very encouraging. We describe 2 cases of Mondini's malformation with severe sensorineural hearing loss. Cochlear implantation was performed and both of them underwent post-implantation speech rehabilitation. Post-imp...

Users of cochlear implants (auditory aids, which stimulate the auditory nerve electrically at the inner ear) often suffer from poor speech understanding in noise. We evaluate a small (intermicrophone distance 7 mm) and computationally inexpensive adaptive noise reduction system suitable for behind-the-ear cochlear implant speech processors. The system is evaluated in simulated and real, anechoi...

To address the challenges in developing miniature directional microphones, a novel micro-fabricated directional microphone inspired by the superacute ears of the parasitoid fly Ormia ocharacea is presented in this paper. It consists of two clamped circular silicon diaphragms structurally coupled by an oxide/nitride composite bridge. The separation between the diaphragm centers is 1.25 mm, about...

This article was investigated to study the correlation and analysis of drought stress regression on maize cultivars' yield components. The variance results showed a significant difference between levels in terms plant height, total dry weight number seeds per row, cob, grain yield, harvest index, stem diameter, cob with protective leave. Also, there ear without leaves, length, weight, 100-seed ...

The cochlear implant or bionic ear, is a small device that can be implanted under the skin and within the cochlear, and has been developed to assist profoundly deaf people. The device is quite different from a hearing aid, as it does not amplify sound, but replaces 'natural' sound with coded, electronic 'messages' which describe sound. For the first time in history, people who are technically, ...

The novel once-daily β₂-agonist bronchodilator drug olodaterol has recently been shown to be effective in patients with allergic asthma for >24 hours. An increased cholinergic tone common to these patients may decrease the effectiveness of β₂-agonists. This could provide a rationale for combination therapy with olodaterol and the long-acting anticholinergic tiotropium to aim for a once-daily tr...

Introduction Frequent visits to rule out acute otitis media or to verify resolution of middle ear fluid accumulation occupy a substantial number of pediatric office appointments and emergency department visits, many of which are unnecessary. Clinical studies and experience have shown that acute otitis media is difficult to diagnose by symptoms alone and is frequently overdiagnosed by parents of...

Animal studies have shown that toluene can cause hearing loss and can exacerbate the effects of noise by inhibiting the middle ear acoustic reflex. In this investigation, carried out in Long-Evans rats, the tensor tympani tendon was cutoff and the stapedius muscle was electrocoagulated in one or both middle ears. Rat hearing was evaluated by measuring cubic distortion otoacoustic emissions (2f1...
