背景情况:
- 单侧耳聋 (SSD) 在骨传导装置 (BCD) 和对侧信号路由 (CROS) 助听器之间选择设备时存在挑战.
- 对于SSD患者在BCD和CROS之间进行选择,存在有限的临床指南.
- 评估真实世界的听力益处对于有效的临床决策至关重要.
研究的目的:
- 确定客观和主观的倾听力度是否可以确定SSD中BCD和CROS的临床相关益处.
- 调查SSD的最佳设备选择是否在个人之间有所不同.
- 在现实的听力场景中评估BCD和CROS的疗效.
主要方法:
- 13名患有SSD的参与者在无助,BCD和CROS条件下完成了听力噪声测试.
- 用NASA任务负载指数 (NASA-TLX) 调查问卷来衡量主观的倾听力度.
- 通过使用眼睛跟踪眼镜,通过峰值瞳孔扩张 (PPD) 评估客观听力.
主要成果:
- 在无辅助,BCD和CROS条件之间没有发现PPD或NASA-TLX得分的统计学上显著差异.
- 一个趋势表明,随着BCD和CROS的使用,PPD减少了,这表明潜在的倾听力度减少.

01:31Hearing
When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.
01:17Auditory Perception
The auditory system is essential for sound perception, utilizing various critical structures. When sound waves enter the outer ear, they travel through the ear canal and cause the eardrum to vibrate. These vibrations are then transmitted to the middle ear, where three tiny bones – the malleus, incus, and stapes – amplify the sound. This amplification is crucial, as it ensures that the sound vibrations are strong enough to be conveyed to the inner ear. These vibrations then reach the cochlea, a...
01:21Perceiving Loudness, Pitch, and Location
The human brain perceives pitch through two primary mechanisms reflected in place theory and frequency theory. Each mechanism describes how sound waves are interpreted as specific pitches by the brain, offering insights into the intricate processes of auditory perception.
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 identifying...
