可以通过允许用户进行自我调节来微调个人听力设备（诸如助听器）。两个自我调整程序被开发出来，以收集从0.25 kHz到8 kHz的六个倍频程频带的听众的首选增益。这些过程被设计为允许使用简单的一维用户控制界面（即，可编程旋钮）。这两个过程的不同之处在于，在给定试验中，用户界面是同时控制所有频带中的增益（过程A）还是仅控制一个频带中的增益（过程B）。蒙特-卡罗模拟表明，对于这两种程序，由模拟听众识别的增益偏好在前20次试验中迅速收敛到地面实况偏好增益分布。初步的自我调节程序的行为评估，在重测信度方面，进行了使用20名年轻，听力正常的听众。对首选增益曲线的每次估计花费的时间不到20分钟。两次独立的增益分布估计之间的偏差约为10 dB ~ 15 dB，这两次估计间隔至少一周。
Personal hearing devices, such as hearing aids, may be fine-tuned by allowing the users to conduct self-adjustment. Two self-adjustment procedures were developed to collect the listener preferred gains in six octave-frequency bands from 0.25 kHz to 8 kHz. These procedures were designed to allow rapid exploration of a multi-dimensional parameter space using a simple, one-dimensional user control interface (i.e., a programmable knob). The two procedures differ in whether the user interface controls the gains in all frequency bands simultaneously (Procedure A) or only the gain in one frequency band (Procedure B) on a given trial. Monte-Carlo simulations suggested that for both procedures the gain preference identified by simulated listeners rapidly converged to the ground-truth preferred gain profile over the first 20 trials. Initial behavioral evaluations of the self-adjustment procedures, in terms of test-retest reliability, were conducted using 20 young, normal-hearing listeners. Each estimate of the preferred gain profile took less than 20 minutes. The deviation between two separate estimates of the preferred gain profile, conducted at least a week apart, was about 10 dB ~ 15 dB.
