This systematic review evaluated the impact of using digital pinna-cue preserving technologies (PPT) on front/back sound localization for adult hearing aid users. Two peer-reviewed studies and two non-peer-reviewed studies were included. Lab-based and self-report outcomes were both assessed. The overall findings suggested that PPT was superior to omni-directional and full directional settings in a relatively quiet, well-controlled laboratory environment but not in the real world. However, observed individual differences in self-report measures suggested that PPT was potentially beneficial to certain hearing aid users. PPT candidacy was discussed and the importance of a pre-fitting interview/consultation was emphasized to assist clinicians in making a solid evidence-based and cost-effectiveness decision when prescribing hearing aids to adults with hearing impairment.
本系统评价评估了使用数字耳廓线索保留技术（PPT）对成年助听器使用者前后声音定位的影响。纳入了两项同行评审研究和两项非同行评审研究。对基于实验室的结果和自我报告结果均进行了评估。总体研究结果表明，在相对安静、控制良好的实验室环境中，PPT优于全向和全指向设置，但在现实世界中并非如此。然而，自我报告测量中观察到的个体差异表明，PPT可能对某些助听器使用者有益。讨论了PPT的适用情况，并强调了预适配访谈/咨询的重要性，以帮助临床医生在为有听力障碍的成年人开处方助听器时做出坚实的循证和成本效益决策。
