Not all of the variance in speech-recognition performance of cochlear implant (CI) users can be explained by biographic and auditory factors. In normal-hearing listeners, linguistic and cognitive factors determine most of speech-in-noise performance. The current study explored specifically the influence of visually measured lexical-access ability compared with other cognitive factors on speech ...

Compromised temporal resolving power of the auditory system can be one of the main factors contributing to poor speech perception skills in the elderly. Very few of the earlier studies have systematically examined this aspect. Hence, the current study was designed with the following objectives: 1) To establish normative database of Gaps in Noise (GIN) test in elderly population in an Indian con...

This is a sequel of our previous work [8] on characterization of maximum sum rate of slotted Aloha networks. By extending the analysis to incorporate the capacity-achieving receiver structure, Successive Interference Cancellation (SIC), this paper aims to identify the rate loss due to random access. Specifically, two representative SIC receivers are considered, i.e, ordered SIC where packets ar...

The advent of diversity modulation and signal processing has changed the underlying assumption of the conventional collision model that at most one packet can be received at each node of a network. The use of antenna arrays, code division multiple access (CDMA), and space-time processing with multiuser detection makes multipacket reception (MPR) a more realistic model for the physical layer of ...

HEARING AID USE AND SPEECH PERCEPTION Associations between tinnitus characteristics and sleep difficulties were also analyzed separately with four ancillary groups, including the potential candidates for cochlear implantation (Candidate group), to estimate the potential independent and combined contributions of hearing aid (HA) use and poor speech perception. Post-hoc contrasts were also analyz...

Introduction: In developing countries, chronic otitis media (COM) and cholesteatoma are relatively prevalent.  Within the field of otology, COM surgery remains one of the most common surgical treatments. Most recent studies evaluating the potential prognostic factors in COM surgery have addressed graft success rate and types of middle ear and mastoid pathology. There has been much controversy a...

OBJECTIVES Approximately one in five stroke survivors suffer from difficulties with speech reception in noise, despite normal audiometry. These deficits are treatable with personal frequency-modulated systems (FMs). This study aimed to evaluate long-term benefits in speech reception in noise, after daily 10-week use of personal FMs, in non-aphasic patients with stroke with auditory processing d...
