贝叶斯适应程序准确地估计了正常听力和听力受损的听众的声音增长和相同的声音轮. 这些方法为各种听力条件提供可靠的听力学数据.
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.
- 计算统计的计算统计.
背景情况:
- 估计噪音增长对于理解听觉感知至关重要.
- 在频率上精确地调整大声度是很有挑战性的,特别是对于听力损失的人来说.
- 贝叶斯适应程序为有效的数据收集提供了一个潜在的解决方案.
研究的目的:
- 开发和比较贝叶斯适应程序来估计噪音增长.
- 评估不同模型在指导刺激选择方面的表现.
- 评估这些程序对正常听力和神经感官听力损失的听众的准确性.
主要方法:
- 贝叶斯适应程序的开发,用于分类的噪音缩放.
- 模拟实验使用跨十个频率的多项心理测量函数.
- 使用现象学和数据驱动类别边界模型的程序的比较.
- 包括一个非贝叶斯适应程序用于基线比较.
主要成果:
- 所有适应性程序都产生了对声量类别边界和相同声量轮 (250-8000 Hz) 的收估计.
- 数据驱动的模型装配显示了令人满意的准确性.
- 在100次试验中,程序在相同音量级的轮 (20-100) 中达到6dB以下的平方根平均误差.
结论:
- 贝叶斯适应程序是有效的估计声音的增长在一个广泛的频率范围.
- 选择建模方法和刺激选择规则对整体准确性没有显著影响.
- 这些方法为正常听力和听力受损者提供可靠的听力学数据.

Perceiving Loudness, Pitch, and Location
Place theory, or place coding, suggests that different pitches are heard because various sound waves activate specific locations along the cochlea's basilar membrane. The brain determines the pitch of a sound by...
