Sound Intensity Level00:53

Sound Intensity Level

4.1K
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...

科学领域:

  • 听力学 听力学是指听力学.
  • 听力科学 听力科学
  • 语音和听力科学 语言和听力科学

背景情况:

  • 助听器装配通常会与低或过度放大声音作斗争.
  • 在日常的声音水平上量化辅助听力对于有效的助听器使用至关重要.

研究的目的:

  • 实施和评估两种新的噪音听力测试 (HINT) 变体,用于在日常声音水平的下限和上限评估辅助听力.
  • 为了确定这些新的HINT变体在成年助听器用户中的测试-重新测试可靠性.

主要方法:

  • 30名成年助听器使用者参与了这项研究.
  • 一个测试电池包括标准的丹麦HINT,一个低值的HINT变体和一个高值的HINT变体.
  • 参与者两次完成了测试电池,以评估测试-重新测试可靠性.

主要成果:

  • 这两种新的HINT变种都表现出高的测试-重新测试可靠性,测试-重新测试差异的效果大小很小.
  • 皮尔森相关系数表明所有HINT版本的测试和重新测试之间存在强烈和显著的相关性.
  • 在受试者内部的标准偏差为标准HINT的0.8 dB,低端测试的0.9 dB,高端测试的2.2 dB.

结论:

  • 新的下端和上端的HINT变体提供了对助听器的一致和可靠的测量.
  • 这些测试是优化助听器放大和改善患者结果的宝贵工具.
