The speech-evoked auditory brain stem response (speech ABR) is widely considered to provide an index of the quality of neural temporal encoding in the central auditory pathway. The aim of the present study was to evaluate the extent to which the speech ABR is shaped by spectral processing in the cochlea. High-pass noise masking was used to record speech ABRs from delimited octave-wide frequency...

BACKGROUND The aim of this study was to investigate the association between sex and speech-ABR in adults, and its relationship to sex hormone levels. MATERIAL AND METHODS Speech-ABR were elicited with the consonant-vowel syllable (/da/) in a total of 35 adults. Reproductive hormone levels were also measured. RESULTS The transient response of the speech-ABR (waves V, A, and O) in females show a ...

In this contribution, we present an analysis of the effect of changing RM cell intervals on ABR performance. We describe our newly developed ABR model in OPNET. This OPNET ATM model contains enhanced features to support the QoS capabalities of ATM, and a comprehensive ABR feedback model. We describe the various features of the ATM model, and use it for our simulation and analysis.

The auditory-brainstem response (ABR) to short and simple acoustical signals is an important clinical tool used to diagnose the integrity of the brainstem. The ABR is also employed to investigate the auditory brainstem in a multitude of tasks related to hearing, such as processing speech or selectively focusing on one speaker in a noisy environment. Such research measures the response of the br...

The auditory brainstem response (ABR) is a test widely used to assess the integrity of the brain stem. Although it is considered to be an auditory-evoked potential that is influenced by the physical characteristics of the stimulus, such as rate, polarity and type of stimulus, it may also be influenced by the change in several parameters. The use of anesthetics may adversely influence the value ...

The volume of video traffic is continuing to grow rapidly over cable networks. While a majority of IP video on DOCSIS networks today is over-the-top video from third parties, operators are increasing the amount of programming their subscribers can access on IP video-capable devices. Additionally many operators are pursuing IP video deployments that are at various stages from planning, testing, ...

The cost eeective ABR service is suitable for transmitting bursty compressed video over ATM network. Here, we propose a Fast Buuer Fillup (FBF) scheme to run VoD over ATM network with ABR service. We develop models to determine buuer size at the client and the server for our scheme. We also develop relationships between the startup delay, the ABR service parameters, and the network congestion s...

OBJECTIVE To use the over-complete discrete wavelet transform (OCDWT) to further examine the dual structure of auditory brainstem response (ABR) in the dog. METHODS ABR waveforms recorded from 20 adult dogs at supra-threshold (90 and 70dBnHL) and threshold (0-15dBSL) levels were decomposed using a six level OCDWT and reconstructed at individual scales (frequency ranges) A6 (0-391Hz), D6 (391-...
