Digital ear scanner : measuring the compliance of the ear
… paper seeks to resolve the biggest problem with hearing aids, their physical fit. By digitally scanning the ear canal and taking the dynamics of the ear into account the performance and comfort of a hearing aid can be greatly improved. Current optical techniques for 3-D imaging are too expensive …

The Virtual Ear: Deducing Transducer Function in the Drosophila Ear
Die mechano-elektrische Transduktion bildet das Zentrum des Hörprozesses bei Drosophila. Durch vor Kurzem vorgenommene Studien über das Hörsystem von Vertebraten und Invertebraten wurden neue Erkenntnisse über die Funktionsweise der Transduktionsmaschinarie gewonnen. Die meisten Proteine, die diese …

Towards unconstrained ear recognition
… from the unique signature provided by their ears. Specifically, the work develops techniques to support a hypothesis that: The constraints on the use of ear-based biometric systems can be relaxed significantly through the introduction of robust recognition techniques. Two novel techniques …

Playing the Ear: Non-Linearities of the Inner Ear and their Creative Potential
… psychoacoustic phenomena relating to the non-linear nature of the inner ear as an electroacoustic compositional tool. The compositions included in this portfolio explore the validity of a variety of non-linear inner ear phenomena within composition by employing them as primary compositional …

Effects of ear-canal geometry and middle-ear pressure on wideband acoustic reflectance
… immittance (WAI) measurements of the middle ear are studied. The body of work presented here has three major components: (1) design of a hearing measurement probe and probe tip, (2) extraction of the effects of the residual ear canal (REC) and estimation of the WAI at the tympanic membrane …

The English IPA ear trainer
… of the Web 2.0 age for second language learning purposes. However, many applications lack a solid pedagogical foundation or evidence-based reasoning in the application’s design. This study focused on the creation of a browser-based language learning application to aid language learners’ …

Ear Reconstruction. Clinical and physiological evaluations.
… 10,000 births. Reconstruction of the external ear is possible by using autologous rib cartilage in three surgical steps: rib cartilage transplantation, ear elevation and final adjustments. Although the aesthetic result is most essential, there are also functional aspects of a reconstruction of …

Middle ear development: Genetics and disease
The mammalian middle ear is composed of three bony ossicles, the malleus, incus, and stapes that function to conduct sound from the external to the inner ear. Normal development of middle ear structures is integral for transduction of sound, defects resulting in conductive deafness. Mice are …

In-ear Audio For Physiological Monitoring
Wearable devices are revolutionising personal health and fitness monitoring by enabling real-time, continuous, and non-invasive tracking of various physiological parameters. Among wearables, earables (sensor-equipped earbuds) have emerged as a promising platform for physiological sensing due to …

On Pressure Regulation of the Middle Ear
The middle ear (ME) pressure is regulated by gas diffusion over the ME mucosa and pressure equalizations via the Eustachian tube (ET). Disturbance in the regulation of ME pressure is believed to contribute to the development of chronic ear diseases. In this work subjects with chronic central …

High Schoolers' Approaches to Learning Melodies by Ear
Aural learning, sometimes called “learning by ear,” is a fundamental mechanism of music, connected to musical perception, acquisition, and understanding. Researchers have primarily studied aural learning strategies through self-reported data or qualitative observations. Because the interaction …

On guided model-based analysis for ear biometrics
Ears are a new biometric with major advantage in that they appear to maintain their structure with increasing age. Current approaches have exploited 2D and 3D images of the ear in human identification. Contending that the ear is mainly a planar shape we use 2D images, which are consistent with …

Treatment of early middle ear cholesteatoma by atticosinoplasty
BACKGROUND AND OBJECTIVES: Treatment of early cholesteatoma usually involves surgical modification of mastoid antrum and tympanum to prevent recurrence. Reconstruction of ossicular chain and the ear drum after complete elimination of cholesteatoma in tympanum improves hearing greatly. However, like …

Characterizing middle ear reflectance via pole-zero fitting
This thesis characterizes middle ear complex acoustic reflectance (CAR) and impedance by fitting poles and zeros to real-ear measurements. The goal of this work is to establish a quantitative connection between pole-zero locations and the underlying physical properties of CAR data. Most previous …
