概括
在噪音耐受性测试 (TNT) 中使用国际语音测试信号 (ISTS) 对听力正常的听众的影响要大于听力损失的听众. 这项研究探讨了噪音耐受性的声学和非声学因素.
科学领域:
- 听觉神经科学 听觉神经科学
- 精神声学是一种精神声学.
- 语音感知 语音感知
背景情况:
- 追踪噪声耐受性 (TNT) 测试评估一个人容忍背景噪声的能力.
- 听众在TNT测试中的表现可能会受到目标信号的性质的影响,无论是有意义的语音还是无意义的刺激.
研究的目的:
- 评估如何使用国际语音测试信号 (ISTS),一个无意义的听觉刺激,影响听众在TNT测试的结果.
- 检查TNT测试结果,听力损失和中枢听力抑制的神经生理测量之间的关系.
主要方法:
- 一项单盲混合设计研究涉及23名正常听力 (NH) 和16名听力受损 (HI) 的老年人.
- 参与者完成了一个修改后的TNT测试,使用ISTS作为目标信号和动态背景噪声,通过噪声接受 (TNTAve) 和噪声水平波动 (游览) 测量性能.
- 皮层感官门的大小被记录为中央抑制的电生理学指数.
主要成果:
- 与英语语语相比,正常听觉的听众与ISTS目标相比容忍噪音较少,而听力受损的听众在噪音接受方面没有差异.
- 听力受损的听众与听力正常的听众不同,在ISTS目标的噪音水平上表现出更大的波动 (游览).
- TNT外游与纯色调平均值有很强的相关性,感官门的大小预测了TNT外游和噪声接受,无论目标类型如何.
结论:
- 用无意义的ISTS目标取代有意义的语言对正常听力与听力受损的听众的TNT测试表现产生不同影响.
- 对有意义和无意义信号的TNT结果进行比较,可以了解影响动态噪声耐受性的声学和非声学因素.
- 中枢抑制的神经生理测量与个体在听觉任务期间管理波动的背景噪音的能力有关.

4.0K
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...

The human ear cannot distinguish between two sources of sound if they happen to reach within a specific time interval, typically 0.1 seconds apart. More than this, and they are perceived as separate sources.
Imagine the sound is reflected back to the ears. Assuming that the source is very close to the human, the difference between hearing the two sounds—the emitted sound and the reflected sound—may be more than the minimum time for perceiving distinct sounds. If this is the case,...

Heart sounds are generated by the turbulence in blood flow due to the closing of heart valves. These sounds are best perceived slightly away from the valves, where the blood flow disseminates the sound.
Auscultation is the process of listening to these internal body sounds using a stethoscope. The heart produces four types of sounds, but only two—S1 and S2—can usually be heard with a stethoscope.
S1, also known as the "lub" sound, is caused by the closure of atrioventricular (A-V)...
