概括
对象和主观语音可理解度的测量对正常听力听众来说是一致的,但对于听力受损者来说是不同的. 助听器可以提高听力受损的听众的客观和主观可理解性.
科学领域:
- 听力学 听力学是指听力学.
- 语音科学 语言科学
- 听力健康 听力健康
背景情况:
- 客观和主观语音可理解性测试在最低限度的上下文下产生类似的结果.
- 这些措施与语境语音材料的可比性仍然不清楚.
研究的目的:
- 为了比较正常听力 (NH) 和听力受损 (HI) 听众之间的客观和主观可理解性差异 (OSID).
- 在无助和助听器 (HA) 辅助条件下使用语境语音材料来评估OSID.
主要方法:
- 采用了一种单盲,主体内设计.
- 24名NH和17名HI的老年人参与了这项研究.
- 客观和主观语音接收值 (SRT50s) 用噪声耐受性跟踪 (TNT) 测试进行测量,并计算OSID.
主要成果:
- 在无助条件下,NH听众表现出比HI听众更好的客观和主观SRT50s.
- 显著的相互作用显示HI听众的主观SRT50低于客观SRT50,特别是在无助条件下.
- 助听器提高了HI听众的客观和主观可理解性.
- 在客观和主观SRT50之间发现了中度至强度的相关性,除了使用HA的HI听众.
结论:
- 在NH听众中,客观和主观语音可理解性是可比的.
- 高频听力者表现出更好的主观比客观可理解性,无论无助或辅助状态.
- 助听器的使用可以提高HI听众的语音可理解性.

01:09Comparing Experimental Results: Student's t-Test
1.6K
The t-test is a statistical method used to compare the sample mean with a population mean or compare two means from two data sets. The test statistic is calculated from the standard deviation, mean, and number of measurements in the data set at a selected confidence interval and then compared to a table of critical values at this confidence level. If the test statistic is smaller than the critical value, the null hypothesis is accepted. In this case, we state that the difference between the...

Humans perceive sound by hearing. The human ear helps sound waves reach the brain, which then interprets the waves and creates the perception of hearing. The loudness of the environment in which a person is located determines whether they can distinguish between different sound sources.
The human ear can perceive an extensive range of sound intensity, necessitating the use of the logarithmic scale to define a physical quantity—the intensity level. It is a ratio of two intensities and...
