This study examined (1) the effects of noise on speech understanding and (2) whether performance in real-life noises could be predicted based on performance in steady-state speech-spectrum-shaped noise. The noise conditions included a steady-state speech-spectrum-shaped noise and six types of real-life noise. Thirty normal-hearing adults were tested using sentence materials from the Cantonese H...

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...

Speech utterances in a given language are known to be less intelligible to second-language (L2) listeners than to native listeners. This study is aimed at quantifying the reduction of speech intelligibility due to non-nativeness of the listener. Two types of experiments were carried out: Speech Reception Threshold (SRT) experiments for obtaining a quantitative measure of speech intelligibility,...

Demonstration of successful outcomes from use of a sensory device by individuals with hearing loss depends to a large extent on quantifiable improvements in auditory performance. Quantifiable improvements are typically characterized by speech perception outcomes, which involve speech awareness/detection, reception, discrimination, identification or recognition of speechtype materials (e.g., pho...

Musicians can sometimes achieve better speech recognition in noisy backgrounds than non-musicians, a phenomenon referred to as the "musician advantage effect." In addition, musicians are known to possess a finer sense of pitch than non-musicians. The present study examined the hypothesis that the latter fact could explain the former. Four experiments measured speech reception threshold for a ta...

Measures of speech intelligibility are an essential tool for diagnosing hearing impairment and for tuning hearing aid parameters. This study explores the potential of automatic speech recognition (ASR) for conducting autonomous listening tests. In these tests (e.g., in the Oldenburg sentence matrix test employed here) the responses of participants are usually logged by a (human) supervisor. The...

introduction: the use of cartilage as a grafting material has been advocated in cases where there is a high risk of graft failure, such as subtotal perforations, adhesive processes, and residual defects after primary tympanoplasties. the purpose of this study was to compare the graft acceptance rates and auditory outcomes of cartilage tympanoplasty operations using a palisade technique with tho...

In this paper, the effects of multipacket reception (MPR) capability on the capacity of wireless networks with regular structures are analyzed. Under uniform traffic and minimum connectivity, the maximum stable packet generation rate for the MPR Manhattan networks is obtained. For a network of size N , it is shown that the capacity is K1/ √ N , and adding MPR affects the coefficient K1 of a non...
