A new, fast screening algorithm based on auditory brainstem response (ABR) recorded at a high click repetition rate is proposed. Response detection is carried out in the frequency domain by a statistical test procedure which includes the fundamental frequency and the harmonics below 800 Hz. First, the method was tested in 25 young adults. ABRs were recorded in the repetition rate range 20/s to 400/s. With a mean response detection time of 31 s, a click repetition rate of 140/s was found to be the optimum rate among the adult group. The method was then tested using a group of 114 neonates in whom the repetition rate range 60/s to 200/s was examined. At the repetition rate 90/s, which was found to be the optimum rate in neonates, the mean detection time was 24.6 s. In addition to the fast ABR detection, the proposed screening algorithm also allows simultaneous hearing screening of both ears using a one-channel data recording.
提出了一种基于高点击重复率记录的听觉脑干反应(ABR)的新型快速筛查算法。通过统计测试程序在频域中进行反应检测,该程序包括基频和800Hz以下的谐波。首先,该方法在25名年轻成年人中进行了测试。在20/秒至400/秒的重复率范围内记录ABR。平均反应检测时间为31秒,发现140/秒的点击重复率是成年组中的最佳速率。然后使用一组114名新生儿对该方法进行测试,其中检查了60/秒至200/秒的重复率范围。在90/秒的重复率下,这被发现是新生儿中的最佳速率,平均检测时间为24.6秒。除了快速ABR检测外,所提出的筛查算法还允许使用单通道数据记录同时对双耳进行听力筛查。
