In this paper we report on a multi-resonant transducer that may be used to replace a traditional speech processor in cochlear implant applications. The transducer, made from an array of micro-machined polymer resonators, is capable of passively splitting sound into its frequency sub-bands without the need for analog-to-digital conversion and subsequent digital processing. Since all bands are me...

The Contralateral Routing of Signal (CROS) device is one recommended solution for individuals with Single-Sided Deafness (SSD). BiCROS is the adaptation for individuals who also need amplification in the better ear. Phonak Audiology and Research Center (PARC) took an in-depth look at the sound quality, sound cleaning and general usability of the Phonak CROS II compared to a competitive CROS dev...

Aiming to address the problems of low working efficiency and high damage rate roller peeling equipment in process fresh corn harvesting China, this paper theoretically analyzes mechanical motion between device ear, a high–low roll structure is proposed. This incorporates elastomeric rubber material, segmentation design, an adjustable spiral frame, selection relevant parameters given. To determi...

BACKGROUND The effect of division of the stapedial tendon on susceptibility to noise-induced inner ear damage has not been previously studied. This study aimed to evaluate the effects of noise exposure following division of the stapedial tendon in guinea pigs. MATERIAL AND METHODS Ten adult albino guinea pigs were used. The stapedial tendon of each right ear was cut. The stapedial tendon in e...

The objectives of the present study were to (i) estimate noise levels at major traffic junctions in Bengaluru City, and (ii) assess the knowledge, attitude and practices of traffic policemen deputed at those junctions towards the auditory effects caused by noise pollution. The present questionnaire based study was carried among 60 traffic policemen. Road traffic noise was measured at different ...

Cell-mediated immunity has been shown to be clinically important in recovery from herpes simplex virus (HSV) infections. To investigate the role of delayed hypersensitivity (DH) in immunity and protection against HSV, we developed a murine model using the ear-swelling assay. Mice were infected subcutaneously with HSV-1 and ear-challenged, and the swelling was quantified. Significant ear swellin...

The aim of the present study was to evaluate possible protective effects of corticosteroids on the inner ear after surgical trauma and to exclude any ototoxicity. A corticosteroid (triamcinolone, Volon A) was topically applied to the inner ear of guinea pigs, either by extracochlear application with permeation and diffusion through the round window membrane or by intracochlear application with ...

In this study, we describe a technique for estimating meal times using an earphone-type wearable sensor. A small optical sensor composed of a light-emitting diode and phototransistor is inserted into the ear hole of a user and estimates the meal times of the user from the time variations in the amount of light received. This is achieved by emitting light toward the inside of the ear canal and r...
