  • Title: Auditory brainstem responses recorded at fast stimulation rates using maximum length sequences.
    Author: Thornton AR, Slaven A.
    Journal: Br J Audiol; 1993 Jun; 27(3):205-10. PubMed ID: 8241969.
    Abstract:
    There are now commercially available systems which can provide maximum length sequence averaging techniques. This study examines the effects on auditory brainstem response amplitude and latency of using such a system and stimulating at rates from 9 to 1000 clicks/s. As expected there is considerable adaptation of the response such that at 1000 clicks/s wave V amplitude is only approximately 8% of its low stimulation rate value. As the stimulation rate is increased so the test time taken to obtain a response of the same signal-to-noise ratio as a conventional recording decreases. This process continues up to a maximum click rate of about 200 clicks/s. Thereafter, the response adapts so rapidly that further increases of rate lead to a worsening of performance. Thus, the optimum stimulation rate appears to be of the order of 200 clicks/s and this can give a speed improvement by a factor of approximately 2.8 over conventional recordings taken at 9 or 10 clicks/s.
