概括
为了在噪音中提高语音理解,对奥尔登堡句子测试来说,120个句子的培训课程至关重要. 结果表明,右耳在语音歧视方面具有优势,强调需要进行特定耳朵的分析.
科学领域:
- 听力学 听力学是指听力学.
- 精神声学是一种精神声学.
- 语音处理 语音处理
背景情况:
- 双耳听力对于在噪音和空间定向中理解语音至关重要.
- 本研究评估了评估这些双耳听力方面的方法.
研究的目的:
- 为了调查与分离的声音来源的噪音中的语音歧视.
- 测量声音定位的准确性和可重现性.
- 评估两种选择的双耳听力测量技术的特征.
主要方法:
- 收集了55名正常听力成年人使用奥尔登堡句子测试的语音接收值 (SRT) 噪音和测试复试可靠性.
- 使用的空间扬声器设置 (±45°,±90°) 用于语音测试和半圆/全圆设置 (7/12扬声器) 用于声音定位.
主要成果:
- 在噪音和分离信号中语音可理解性的SRT值在-13.1到-16.4dB SNR之间.
- 测试复试可靠性为4-6dB SNR,过程性学习效应被120个训练句子减轻.
- 对右耳观察到明显更好的语音歧视 (较低的SRT),这表明右耳具有优势. 在全圆设置重复测试中,声音定位的准确性得到了改善 (半圆的11.1°与1.9°相比).
结论:
- 120个句子的训练是强制性的奥尔登堡句子测试在噪音与空间分离的信号,以最大限度地减少程序学习.
- 由于右耳的优势,对于准确的语音歧视评估,需要特定于耳朵的SRT值.
- 建议在全圆设置中训练声音定位,以提高准确性.

01:29Hearing During Infancy and Toddlerhood
Hearing begins developing before birth. Fetuses respond to sounds in the womb through changes in brain activity, heart rate, and body movements, showing sensitivity to auditory stimulation. After birth, hearing continues to develop rapidly, supporting language learning and environmental awareness.Auditory Acuity and Sound LocalizationAuditory acuity refers to the ability to detect sounds. Newborns are especially responsive to human voices and can detect many speech sounds, although their...
01:20Perceiving Language Sounds and Structure During Infancy
Infants are born with a predisposition to perceive and categorize basic linguistic sounds. Early in development, they can discriminate sounds from many languages and detect differences in rhythm and pattern. This sensitivity may begin before birth. Newborns exposed to two languages prenatally can recognize both, indicating that fetal language exposure influences later auditory discrimination.Recognition of Familiar SoundsBy five months, infants show preferences for familiar auditory stimuli,...
