“…The MLS method has been widely used not only with AEPs (e.g., Leung et al, 1998;Bohorquez and Ozdamar, 2006;Lavoie et al, 2010), but also with transient evoked otoacoustic emissions (e.g., Hine et al, 2001;Thornton and Slaven, 1993;de Boer et al, 2007). The distribution of the ISI in this method is adjusted to De-Bruijn sequences, in which a k-ary de-Bruijn sequence B(k, n) of order n of a given alphabet A is a pseudorandom cyclic sequence with size k for which every possible subsequence of length n appears in the sequence exactly once (Tuliani, 2001;Burkard et al, 1990).…”

Randomized stimulation and averaging (RSA) allows auditory evoked potentials (AEPs) to be recorded at high stimulation rates. This method does not perform deconvolution and must therefore deal with interference derived from overlapping transient evoked responses. This paper analyzes the effects of this interference on auditory brainstem responses (ABRs) and middle latency responses (MLRs) recorded at rates of up to 300 and 125 Hz, respectively, with randomized stimulation sequences of a jitter both greater and shorter than the dominant period of the ABR/MLR components. Additionally, this paper presents an advanced approach for RSA [iterative-randomized stimulation and averaging (I-RSA)], which includes the removal of the interference associated with overlapping responses through an iterative process in the time domain. Experimental results show that (a) RSA can be efficiently used in the recording of AEPs when the jitter of the stimulation sequence is greater than the dominant period of the AEP components, and (b) I-RSA maintains all the advantages of RSA and is not constrained by the restriction of a minimum jitter. The significance of the results of this study is discussed.

“…In this technique, the deconvolution of overlapping responses is performed using bursts of pseudorandom pulses whose ISIs are adjusted to De-Brujin sequences. This technique has not only been used to record ABRs at high stimulation rates (e.g., Leung et al, 1998;Bohorquez and Ozdamar, 2006) but also to record mid-latency auditory evoked potentials (e.g., Lavoie et al, 2010) and other biological signals such as transient evoked otoacoustic emissions (e.g., Hine et al, 2001;Thornton, 1993;de Boer et al, 2007). The stimulation technique based in Legendre sequences (LGS) is also adjusted to the De-Brujin sequences.…”

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.
