“…This parameter points out the grade of similarity between two ABR signals. A high positive correlation coefficient would indicate a high quality ABR recording when the two signals are recorded in the same conditions (Mason et al, 1977;Schimmel et al, 1974;Weber and Fletcher, 1980). In comparison with the objective quality assessment methodologies for ABR recordings based on the variance ratio and multiple pre-post Z, the correlation coefficient is considered a more consistent technique to score the quality of ABR recordings (Arnold, 1985).…”

The recording of auditory brainstem response (ABR) at high stimulation rates is of great interest in audiology. It allows a more accurate diagnosis of certain pathologies at an early stage and the study of different mechanisms of adaptation. This paper proposes a methodology, which we will refer to as randomized stimulation and averaging (RSA) that allows the recording of ABR at high stimulation rates using jittered stimuli. The proposed method has been compared with quasi-periodic sequence deconvolution (QSD) and conventional (CONV) stimulation methodologies. Experimental results show that RSA provides a quality in ABR recordings similar to that of QSD and CONV. Compared with CONV, RSA presents the advantage of being able to record ABR at rates higher than 100 Hz. Compared with QSD, the formulation of RSA is simpler and allows more flexibility on the design of the pseudorandom sequence. The feasibility of the RSA methodology is validated by an analysis of the morphology, amplitudes, and latencies of the most important waves in ABR recorded at high stimulation rates from eight normal hearing subjects.

“…Mason et al (1977) calculated the correlation coeffi cient and resulting p value for a series of voltage measures taken at specifi ed sampling points across two averages; each based on 32 epochs. However, the number of degrees of freedom that should be applied to this correlation is signal dependent.…”

The detection of adult cortical auditory evoked potentials (CAEPs) can be challenging when the stimulus is just audible. The effectiveness of a statistic compared with expert examiners in (1) detecting the presence of CAEPs when stimuli were present, and (2) reporting the absence of CAEPs when no stimuli were present, was investigated. CAEPs recorded from ten adults, using two speech-based stimuli, five stimulus presentation levels, and non-stimulus conditions, were given to four experienced examiners who were asked to determine if responses to auditory stimulation could be observed, and their degree of certainty in making their decision. These recordings were also converted to multiple dependent variables and Hotelling's T2 was applied to calculate the probability that the mean value of any linear combination of these variables was significantly different from zero. Results showed that Hotelling's T2 was equally sensitive to the best of individual experienced examiners in differentiating a CAEP from random noise. It is reasonable to assume that the difference in response detection for a novice examiner and Hotelling's T2 would be even greater.

“…Many of the earliest reports on objective methods of evaluating EPs were applied to the late responses to auditory, visual, and so matosensory stimuli (Schimmel, 1967;Sa lomon, 1974;Wicke et al, 1978;Hyde, 1976;Mason et al, 1977). In this article, we con centrate on techniques that have been ap plied to the ABR, but we also introduce other techniques if they are of general relevance.…”
