论文摘要
由于与年龄相关的听力损失，老年人经常在电视上跟随该语言而挣扎。因为它们构成了受众群体的越来越多，所以这个问题将在未来变得更加重要，并且需要通过研发来解决。基于对象的音频是解决此问题的一种有前途的方法，因为它提供了可自定义对话增强（DE）的可能性。对于本论文，进行了调整 /满意度测试（A / ST），以评估65岁以上的人的语音和背景之间的首选响度差异（LD）。对DE进行了两种不同类型的DE：DE具有单独的可用音频组件（语音和背景）（语音和背景），并与盲源分离（BSS）创建的组件（BSS）。与原始的LDS相比，两种DE方法与听众满意度之间的首选LDS的差异进行了测试。据观察，首选的LD大于原始LD，可自定义的DE提高了听众满意度，并且两种DE方法在首选LD和听众满意度方面的性能相当出色。根据结果，可以假定65岁以上的老年观众将通过可用的组件和对话分离从用户调整的DE中受益。
Due to age-related hearing loss, elderly people often struggle with following the language on TV. Because they form an increasing part of the audience, this problem will become even more important in the future and needs to be addressed by research and development. Object-based audio is a promising approach to solve this issue as it offers the possibility of customizable dialogue enhancement (DE). For this thesis an Adjustment / Satisfaction Test (A/ST) was conducted to evaluate the preferred loudness difference (LD) between speech and background in people above 65. Two different types of DE were tested: DE with separately available audio components (speech and background) and DE with components created by blind source separation (BSS). The preferred LDs compared to the original, differences of the preferred LDs between the two DE methods and the listener satisfaction were tested. It was observed that the preferred LDs were larger than the original LDs, that customizable DE increases listener satisfaction and that the two DE methods performed comparably well in terms of preferred LD and listener satisfaction. Based on the results, it can be assumed that elderly viewers above 65 will benefit equally from user-adjustable DE by available components and by dialogue separation.
