概括
年长的成年人在噪音中更难以说话,特别是与空间分离的掩饰器. 年龄和某些听觉敏感性预测了这种减少的语音理解能力.
科学领域:
- 听觉神经科学 听觉神经科学
- 老年学是指老年学的学科.
- 语音感知 语音感知
背景情况:
- 语音噪音 (SiN) 感知随着年龄的增长而下降.
- 了解面具类型和空间位置如何影响老年人SiN至关重要.
研究的目的:
- 调查面具类型 (语音与歪曲语音) 和空间位置对老年人和年轻成年人的SiN表现的影响.
- 检查与年龄相关的SiN缺陷和超值听觉敏感性之间的关系.
主要方法:
- 参与者在各种空间位置 (0°,6°,45°) 用语音或模糊语音掩饰器听到目标语音.
- 对时间调制 (TM),光谱调制 (SM),光谱时间调制 (STM) 和双耳时间细结构 (TFS) 的超值灵敏度被测量.
- 使用iPad上的便携式自动化快速测试软件评估了比赛中的演讲 (SiC) 性能.
主要成果:
- 年长的成年人在SiC上表现更差,特别是在空间分离的掩饰器 (6°,45°) 中,并且在语音掩饰器中从空间分离中获得的益处较小.
- 虽然老年人的整体表现较差,但与年轻人相比,他们同样受益于空间分离.
- 老年人表现出对双耳TFS的敏感性降低,但对TM,SM和STM的敏感性相似.
结论:
- 年龄显著影响SiC的表现,空间分离对使用语音掩饰器的老年人来说提供较少的好处.
- 听觉敏感度,特别是TM和SM,预测了老年人的SiC表现,突出了外围和中央听觉处理的作用.
- 这些发现增强了对老化和听觉处理能力如何影响复杂听力环境中的语音理解的理解.

Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...

Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.
