概括
正常听力定义需要的不仅仅是音调听力测量. 客观的中耳功能测试,如耳测量和耳声排放,为准确的听力评估提供了关键数据.
科学领域:
- 听力学 听力学是指听力学.
- 耳声波排放 耳声波排放 耳声波排放
- tympanometry 音筒计测试 音筒计测试 音筒计测试
背景情况:
- 当前的DIN标准定义了基于声计空气导电值的正常听力.
- 这些标准没有充分考虑特定的中耳功能.
- 这项研究解决了包括客观中耳测量在内的全面听力测量数据的需求.
研究的目的:
- 为了前性地收集用于正常听觉的听力测量数据.
- 用客观的中耳功能数据来补充传统的音调听力测量.
- 调查合规性,共振频率和吸收率在定义正常听力中的作用.
主要方法:
- 评估了84名年轻成年人 (18-25岁) 的耳朵,他们的听力正常,通过音调听力测量.
- 进行了客观的中耳诊断:经典耳计,宽带吸收耳计和步反射值测量.
- 包括扭曲产品的音声发射 (DPOAE) 测量.
主要成果:
- 七个耳朵表现出符合> 2 mmho,具有较低的共振频率和更高的吸收率.
- 在耳朵中观察到不可检测的DPOAEs的发病率更高,其遵守性增加 (14%与5%相比).

UV–Vis Spectrometers
3.3K
The absorbance of UV and visible (UV–visible) radiations is measured using a UV–visible spectrophotometer. Deuterium lamps, which emit UV radiation, and tungsten lamps, which produce radiation in the visible region, are used as light sources in UV–visible spectrophotometers. A monochromator or prism is used for diffraction grating, i.e., to split the incoming radiation into different wavelengths. A system of slits is used to focus the desired wavelength on the sample cell.

Spectrophotometry: Introduction
6.6K
Spectrophotometry is the quantitative measurement of the absorption, reflection, diffraction, or transmission of electromagnetic radiation through a material as a function of the intensity and wavelength of the radiation. A spectrophotometer is a device used to measure the change in the radiation intensity caused by its interaction with the material.
The essential components of a spectrophotometer include a source of electromagnetic radiation, a slot for placing a material to be analyzed, and a...
