Sensorineural hearing loss in elderly patients (presbycusis) relatively often coexists with annoying tinnitus (termed presbytinnitus [PT] by Claussen). The purpose of this study was to verify the conditions of improvement in patients treated for PT. We fitted with hearing aids 33 PT patients (ages 60-89 years) and questioned them about subjective hearing results. Assessment tools included compr...
Acoustic feedback is a problem in hearing aids that contain a substantial amount of gain, hearing aids that are used in conjunction with vented or open molds, and in-the-ear hearing aids. Acoustic feedback is both annoying and reduces the maximum usable gain of hearing-aid devices. This paper studies analytically the steady-state convergence behavior of LMS-based adaptive algorithms when operat...
OBJECTIVE The aim of this study was to assess the main ear malformations, hearing loss and auditory rehabilitation in children with Treacher Collins syndrome. METHODS We performed a retrospective study of 9 children with Treacher Collins syndrome treated in a central hospital between January 2003 and January 2013. RESULTS This study showed a high incidence of malformations of the outer and ...
This study investigated eye-movement patterns during emotion perception for children with hearing aids and hearing children. Seventy-eight participants aged from 3 to 7 were asked to watch videos with a facial expression followed by an oral statement, and these two cues were either congruent or incongruent in emotional valence. Results showed that while hearing children paid more attention to t...
The rated quality and intelligibility of speech processed by hearing aids in which the low-frequency output had been reduced by either electronic modification (low-cut tone controls) or acoustic modification (vented or open earmolds) was investigated. Fifteen subjects with high-frequency hearing loss provided data for nine commercial hearing aids and both high and low background noise levels. R...
Visit us at hearingloss.org and follow @HLAA on Twitter As someone who has had a hearing loss for more than 55 years, I truly feel this is a remarkable time for us. Individuals who wore analog hearing aids prior to the development of programmable and digital hearing aids will easily relate to what I will discuss in this article. Hearing Aid Connectivity: Bridging a Closer Connection to the Worl...
OBJECTIVES Most patients with tinnitus also have hearing loss. Hearing aids have been well-documented to provide amelioration for both hearing and tinnitus problems. Some hearing aids have built-in noise/sound generators that are intended to provide added benefit to patients with tinnitus. It has not been proven, however, whether these "combination instruments" are more effective for tinnitus m...
This report describes important physiological and anatomical aspects of human hearing, including instruments for hearing improvements, i.e. hearing aids. One common problem with hearing aids is acoustic feedback (howling). A new subband Adaptive Feedback Control (AFC) system for hearing aids is proposed. This system detects howling by calculating distances between zero crossings in the subband ...
INTRODUCTION Hearing loss is one of the most disabling impairments. Using a hearing aid as an attempt to improve the hearing problem can positively affect the quality of life for these people. This research was aimed to assess satisfaction of hearing impaired patients with their hearing aids regarding the employed technology and style. MATERIALS AND METHODS This descriptive-analytic cross-sec...
INTRODUCTION Unilateral hearing loss is characterized by a decrease of hearing in one ear only. In the presence of ambient noise, individuals with unilateral hearing loss are faced with greater difficulties understanding speech than normal listeners. OBJECTIVE To evaluate the speech perception of individuals with unilateral hearing loss in speech perception with and without competitive noise,...
