The CustomSoundEP software can record ECAP traces in an automated manner and calculate the ECAP threshold from them. These values are in good agreement with those determined by audiologists. Manual optimization measurements, as needed when using the predecessor version 3 of the software, are done by the software itself in the newer system.
The programming of a cochlear implant speech processor is usually carried out in a subjective manner, influenced by the audiologist and the subject, and it takes considerable time. With increasing numbers of patients there is a growing need for a rapid and reliable technique to measure and analyse neural responses - one which could give suggestions for programming the speech processor and thus shorten the fitting procedure.
In 30 patients, ECAP responses were recorded postoperatively in an automated procedure. ECAP thresholds were determined automatically by the AutoNRT(TM) (Automatic Neural Response Telemetry) software and visually by seven persons.
The time required to determine a TECAP threshold for a single electrode contact was found to be between 0.5 and 1 min.
CustomSoundEP软件能够以自动化方式记录电刺激复合动作电位（ECAP）轨迹，并据此计算ECAP阈值。这些值与听力学家测定的值高度一致。在较新系统中，使用该软件的旧版本3时所需的手动优化测量现在由软件本身完成。
人工耳蜗言语处理器的编程通常是主观进行的，受听力学家和受试者的影响，且耗时较长。随着患者数量的增加，对一种快速可靠的技术来测量和分析神经反应的需求日益增长，这种技术能够为言语处理器的编程提供建议，从而缩短调试过程。
对30例患者术后采用自动化程序记录ECAP反应。由AutoNRT（自动神经反应遥测）软件自动确定ECAP阈值，并由7人进行视觉判定。
发现为单个电极触点确定阈值电刺激复合动作电位（TECAP）阈值所需的时间在0.5至1分钟之间。
