Hearing loss has become very common today. Approximately 10% of the population suffering hearing impairment due to different reasons across the world. Among all most commonly observed sensorineural hearing loss caused due to poor cochlear hair cells function and damages to cochlear nerve. Sensorineural hearing loss is characterized by widening of auditory filter which leads to spectral masking ...

An acceptable noise level (ANL) procedure for measuring hearing aid directional benefit was compared with masked speech reception threshold (SRT) and front-to-back ratio (FBR) procedures. ANL is the difference between the most comfortable listening level and the maximum accepted background noise level while listening to speech. Forty adult subjects wearing their own binaural hearing aids were e...

A randomized investigation and comparison of the speech recognition in noise of hearing aid users using two different assistive listening devices

OBJECTIVE Identify likely predictors for the outcome after contralateral cochlear implantation with a long interimplant delay. STUDY DESIGN Retrospective case reviews. SETTING Outpatient cochlear implant (CI) center. PATIENTS Seventy-three children and adolescents who underwent sequential bilateral cochlear implantation with an interval between both implantations of 5 years or longer. The...

Lip-sync animation is complex and challenging. It promises to be important in natural humancomputer interfaces and entertainment as well as aid in the education of the deaf. It is an important component in creating a realistic human figure. Speech is based on principles from anatomy, physics, and psychophysiology. We discuss some of the issues that make speech so complex to model visually.

Automatic speech recognition (ASR) can provide a rapid means of controlling EAT. Off-the-shelf ASR systems function poorly for users with severe dysarthria because of the increased variability of their articulations compared to ‘normal’ speech. A two-pronged approach has been applied to this problem: 1. To develop a computerised training package which will assist dysarthric speakers to improve ...

Hearing aid users often require a period of time to adjust to new hearing aid signal processing. For example, the auditory system of a novice hearing aid user must accommodate new, amplified sounds; this is often accompanied by improved performance. The same can be said for experienced hearing aid users receiving a new, improved hearing aid fitting (e.g., new audibility of speech cues). This ad...

Dimensions of hearing aid outcome are explored in this paper. First, a variety of hearing aid outcome measures is defined including objective and subjective performance, objective and subjective benefit, satisfaction, and use. Following the definition of these terms, factor analysis is described as a statistical tool that can be of assistance in establishing the number and nature of the relevan...

A new scale, the Hearing Aid Needs Assessment (HANA), was developed in order to examine the relationship between perceived communication needs/expectations with the actual benefit eventually achieved with newly fitted hearing aids. A serial sample of 82 patients completed the HANA prior to hearing aid consultation. A subgroup of 42 patients eventually completed the Hearing Aid Performance Inven...
