A comparative study of eight human auditory models of monaural processing [PDF]

, 2021
A number of auditory models have been developed using diverging approaches, either physiological or perceptual, but they share comparable stages of signal processing, as they are inspired by the same constitutive parts of the auditory system. We compare eight monaural models that are openly accessible in the Auditory Modelling Toolbox.

Pediatric Otoscopy Video Screening with Shift Contrastive Anomaly Detection [PDF]

arXiv, 2021
Ear related concerns and symptoms represents the leading indication for seeking pediatric healthcare attention. Despite the high incidence of such encounters, the diagnostic process of commonly encountered disease of the middle and external presents significant challenge.

Multi-modal data generation with a deep metric variational autoencoder [PDF]

, 2022
We present a deep metric variational autoencoder for multi-modal data generation. The variational autoencoder employs triplet loss in the latent space, which allows for conditional data generation by sampling in the latent space within each class cluster.

Wireless earbuds for low-cost hearing screening [PDF]

arXiv, 2022
We present the first wireless earbud hardware that can perform hearing screening by detecting otoacoustic emissions. The conventional wisdom has been that detecting otoacoustic emissions, which are the faint sounds generated by the cochlea, requires sensitive and expensive acoustic hardware. Thus, medical devices for hearing screening cost thousands of

Transfer learning using deep neural networks for Ear Presentation Attack Detection: New Database for PAD [PDF]

arXiv, 2021
Ear recognition system has been widely studied whereas there are just a few ear presentation attack detection methods for ear recognition systems, consequently, there is no publicly available ear presentation attack detection (PAD) database. In this paper, we propose a PAD method using a pre-trained deep neural network and release a new dataset called ...

Wideband impedance measurement in the human ear canal; In vivo study on 32 subjects [PDF]

arXiv, 2018
The human ear canal couples the external sound field to the eardrum and the solid parts of the middle ear. Therefore, knowledge of the acoustic impedance of the human ear is widely used in the industry to develop audio devices such as smartphones, headsets, and hearing aids.

A new RCM mechanism for an ear and facial surgical application [PDF]

Advances in Service and Industrial Robotics, In press, 2020
Since the insertion area in the middle ear or in the sinus cavity is very narrow, the mobility of the endoscope is reduced to a rotation around a virtual point and a translation for the insertion of the camera. This article first presents the anatomy of these regions obtained from 3D scanning and then a mechanism based on the architecture of the agile ...

Ear-EEG Sensitivity Modelling for Neural and Artifact Sources [PDF]

arXiv, 2022
The ear-EEG has emerged as a promising candidate for wearable brain monitoring in real-world scenarios. While experimental studies have validated ear-EEG in multiple scenarios, the source-sensor relationship for a variety of neural sources has not been established.

The shape of the ear canal [PDF]

, 2005
It is proved that the measurement of the acoustic pressure on the ear membrane allows one to determine the shape of the ear $ uniquely.

Nonlinear dynamics of the mammalian inner ear [PDF]

arXiv, 2015
A simple nonlinear transmission-line model of the cochlea with longitudinal coupling is introduced that can reproduce Basilar membrane response and neural tuning in the chinchilla. It is found that the middle ear has little effect on cochlear resonances, and hence conclude that the theory of coherent reflections is not applicable to the model.
