概括
确定NU-6缩写单词列表的最佳陈述水平对于准确的听力评估至关重要. 与2000 Hz听力值相比,在30-40 dB SL上呈现单词列表,或在不舒服的听力水平以下5 dB,确保可靠的词识别分数.
科学领域:
- 听力学 听力学是指听力学.
- 语音语言病理学 语言病理学
背景情况:
- 像NU-6这样的标准化词汇列表对于评估单词识别至关重要.
- 优化呈现级别可以缩短测试时间,同时保持准确性.
- 根据难度排序的NU-6 (OBD) 列表为缩短的测试协议提供了潜力.
研究的目的:
- 为了确定NU-6按难度排序 (OBD) 的缩写单词列表的最佳呈现级别.
- 确定 2000 Hz 的 dB 感觉水平 (dB SL) 和缩短的协议的结合是否会产生最佳的文字识别分数 (WRS).
- 找到达到音声平衡 (PB) 最大WRS.所需的最低单词数.
主要方法:
- 词识别分数 (WRS) 在34名成年人 (25名有听力损失,9名没有) 的各种呈现水平上收集.
- 最初的呈现水平是基于2000 Hz的听力值,根据需要进行调整.
- 对于听力受损的参与者来说,单词列表也以5dB低于他们的不舒服听力 (UCL) 水平呈现.
主要成果:
- 最初的呈现水平经常不会导致音声平衡 (PB) 的最高分数.
- 达到PBmax通常需要从缩写列表中获得超过10个单词.
- 在参与者之间观察到呈现水平的变化.
结论:
- 对于NU-6 OBD单词列表,相对于2000 Hz的听力值,建议呈现水平至少为30-40 dB SL.
- 应考虑最低呈现水平为35dB HL.
- 如果主要建议是不可行的,呈现单词列表在UCL以下5dB是一个可行的替代方案.

Introduction and Methods of Leveling
64
Leveling is a surveying procedure used to determine elevation differences between distant points. Elevation refers to the vertical distance above or below a reference datum, typically mean sea level (MSL). In the United States, elevations are often referenced to the mean sea level station at Father Point Rimouski along the St. Lawrence Seaway. To make the datum accessible, permanent markers are established throughout the region. These markers, called benchmarks, have known elevations. If the...

Measures of Intelligence
6.4K
Psychologists measure intelligence by using standardized tests that produce a score known as the intelligence quotient or IQ. To understand IQ tests, it's important to recognize the key principles behind their construction: validity, reliability, and standardization.
Validity refers to how well a test measures what it claims to measure. An intelligence test should accurately assess intelligence rather than another characteristic, like anxiety. Criterion validity is one way to evaluate this;...

Complementation Tests
4.8K
A complementation test is a simple cross to identify whether the two mutations are located on the same gene or different genes. It was first performed by Edward Lewis in the 1940s while working on fruit flies. He developed the test to identify the location and arrangement of different mutations on chromosomes.
Organisms heterozygous for different mutations are crossed pairwise in all combinations. If present on different genes, the mutations can complement each other by providing the missing...

Nominal Level of Measurement
27.8K
The way a set of data is measured is called its level of measurement. Correct statistical procedures depend on a researcher being familiar with levels of measurement. Not every statistical operation can be used with every set of data. For analysis, data are classified into four levels of measurement—nominal, ordinal, interval, and ratio.
The data that cannot be measured but can be grouped into categories fall under the nominal level of measurement. Data that is measured using a nominal...
