Accuracy of averaged auditory brainstem response amplitude and latency estimates.
OBJECTIVE The aims were to 1) establish which of the four algorithms for estimating residual noise level and signal-to-noise ratio (SNR) in auditory brainstem responses (ABRs) perform better in terms of post-average wave-V peak latency and amplitude errors and 2) determine whether SNR or noise floor is a better stop criterion where the outcome measure is peak latency or amplitude. DESIGN The ...
متن کاملObjective detection of auditory steady-state responses: comparison of one-sample and q-sample tests.
Auditory steady-state responses (ASSR) are expected to be useful for the objective, frequency-specific assessment of hearing thresholds in small children. To detect ASSR close to the hearing threshold, a powerful statistical test has to be applied. At present, so-called one-sample tests are used. These tests only evaluate the phase, or the phase and amplitude, of the first harmonic, that is, th...
متن کاملInput and output compensation for the cochlear traveling wave delay in wide-band ABR recordings: implications for small acoustic tumor detection.
BACKGROUND The Stacked ABR (auditory brainstem response) attempts at the output of the auditory periphery to compensate for the temporal dispersion of neural activation caused by the cochlear traveling wave in response to click stimulation. Compensation can also be made at the input by using a chirp stimulus. It has been demonstrated that the Stacked ABR is sensitive to small tumors that are of...
متن کاملNew efficient stimuli for evoking frequency-specific auditory steady-state responses.
ASSR is a promising tool for the objective frequency-specific assessment of hearing thresholds in children. The stimulus generally used for ASSR recording (single amplitude-modulated carrier) only activates a small area on the basilar membrane. Therefore, the response amplitude is low. A stimulus with a broader frequency spectrum can be composed by adding several cosines whose frequency interva...
متن کاملفراوانی پتانسیلهای برانگیخته غیر طبیعی در مالتیپل اسکلروزیس: مطالعه مقطعی در 25 بیمار
Background: Visual, brain stem auditory and somatosensory evoked potentials (EPs) have been traditional paraclinical tests to evaluate the competency of sensory tracts in multiple sclerosis (MS) patients. It seems that only one of these EPs could be sufficient, at least as a screening test. The objective of this paper is to evaluate the frequency of these three evoked potentials in definite MS ...
