To develop an algorithm that prescribes targets for bone conduction frequency response shape, compression, and output limiting, along with a clinical method that ensures accurate transforms between assessment and verification stages of the clinical workflow.
Technical report of target generation and validation.
We recruited 39 adult users of unilateral percutaneous bone conduction hearing aids with a range of unilateral, bilateral, mixed and conductive hearing losses across the sample.
The initial algorithm over-prescribed output compared to the user's own settings in the low frequencies, but provided a good match to user settings in the high frequencies. Corrections to the targets were derived and implemented as a low-frequency cut aimed at improving acceptance of the wearer's own voice during device use.
The DSL-BCD prescriptive algorithm is compatible with verification of devices and fine-tuning to target for percutaneous bone conduction hearing devices that can be coupled to a skull simulator. Further study is needed to investigate the appropriateness of this prescriptive algorithm for other input levels, and for other clinical populations including those with single-sided deafness, bilateral devices, children and users of transcutaneous bone conduction hearing aids.
开发一种算法，用于规定骨传导频率响应形状、压缩和输出限制的目标，以及一种临床方法，以确保临床工作流程中评估和验证阶段之间的准确转换。
目标生成与验证的技术报告。
我们招募了39名单侧经皮骨传导助听器的成年用户，样本中存在一系列单侧、双侧、混合性和传导性听力损失情况。
与用户在低频下的自身设置相比，初始算法在低频时过度规定了输出，但在高频时与用户设置匹配良好。对目标进行了修正，并实施了低频截止，旨在提高设备使用过程中佩戴者对自己声音的接受度。
DSL-BCD规定算法与设备验证兼容，并且可以针对可与颅骨模拟器耦合的经皮骨传导听力设备进行微调以达到目标。需要进一步研究来调查该规定算法对于其他输入水平以及其他临床人群（包括单侧耳聋患者、双侧设备使用者、儿童和经皮骨传导助听器使用者）的适用性。
