Ear Canal Signal Converting Method, Ear Canal Transducer and Headset
The Journal of the Acoustical Society of America, 2012A method of converting electrical signals into mechanical vibration by means of a transducer in the human ear, an ear canal transducer and a headset wherein a sensation of hearing is achieved by exciting the tissue of the ear canal directly with said transducer, whereby the vibrations propagate to the tympanic membrane and into the human sound sensing ...

Ear Canal Keratinocyte Culture
Otology & Neurotology, 2007Autologous epidermal sheets obtained by cultivating keratinocytes of the external auditory meatus can be used to repair cutaneous defects of the ear canal. The Rheinwald and Green method has been used to know whether the produced epidermal layer preserves its specificities after the culture.Using a split-thickness skin graft during a functional ear ...

MRI scanners produce significant sound pressure levels (SPLs), sometimes in excess of 120 dBA. While the effect of these SPLs has been explored for adult patients, it is currently unknown how they affect neonatal patients. One approach to understanding the effect of this noise exposure on infants is to use existing experimental data that associates a ...

Otolaryngologic Clinics of North America, 2023
Primary EAC neoplasms include benign and malignant lesions of bony, glandular or cutaneous origin. Small, benign slow growing bony neoplasms are often asymptomatic, diagnosed incidentally and might not require intervention. Both malignant and benign neoplasms of cutaneous and glandular origin can present with symptoms of chronic otitis externa, leading

Ear and Hearing, 1981
The effects of collapse of the external ear canals due to pressure from earphones have been documented and discussed by several authors during the past 2 decades. This report presents a case of ear canal collapse in a child and demonstrates the value of impedance audiometry in cases of collapse of the external ear canal.

Angiofibrolipoma of the Ear Canal
The Laryngoscope, 2005AbstractObjectives/Hypothesis: Described is the first reported case of an angiofibrolipoma of the ear canal in a patient who presented with right‐sided conductive hearing loss and a medial canal stenosis.Study Design: Case report.Results/Conclusion: This variant of lipoma contains mature adipocytes, blood vessels, and dense collagenous tissue.

Ear Canal Hyperostosis—Surfer's Ear
Archives of Otolaryngology, 1977The increased populatiry of surfing has produced a marked augmentation in the incidence of ear canal exostosis. However, when it becomes moderately severe, I prefer to call it "hyperostosis." Exposure to cold ocean water for many years can be an important etiologic factor in hyperostosis.

Management of Ear-Canal Collapse
Archives of Otolaryngology - Head and Neck Surgery, 1982Thresholds were measured at 250, 500, 1,000, 2,000, 3,000, 4,000, 6,000, and 8,000 Hz in 20 normal adult ears and in ten ears from adults with varying amounts of ear-canal collapse. To alleviate the attenuation caused by ear-canal collapse, ear-canal inserts, postauricular pads, or circumaural cushions (Telephonics 510-020) were used with earphones ...

Congenital Anomalies of the Ear Canal
Otolaryngologic Clinics of North America, 2023Congenital anomalies of the external auditory canal (EAC) are classically divided into congenital aural atresia (CAA) and congenital aural stenosis (CAS). CAA can present as an isolated anomaly, unilateral or bilateral, or in the setting of a craniofacial syndrome. Hearing testing (ABR with air and bone conduction thresholds for both ears) early in the

The Journal of the Acoustical Society of America, 2000
An open ear canal hearing aid system is disclosed which comprises a plurality of ear canal tubes sized for positioning in an ear canal of a user so that the ear canal is at least partially open for directly receiving ambient sounds. The open ear canal hearing aid system further comprises a sound processor for amplifying ambient sounds received through ...
