概括

听觉注意力解码 (AAD) 通过视觉线索和更高的目标对面具比率 (TMR) 在听力受损的听众中得到改善. 个人的听觉能力,如振幅调制灵敏度,影响这些改进.

科学领域:

神经科学是一个神经科学.
听觉神经科学听觉神经科学
语音感知语音感知

背景情况:

听觉注意力解码 (AAD) 识别了辅助语音,但其在听力受损 (HI) 听众中的调制尚不清楚.
了解影响AAD的因素对于开发HI个体的辅助听力技术至关重要.

研究的目的:

调查听力和视觉因素如何调节听力受损听众的AAD.
为了将AAD的表现与个人的听觉能力相关联.

Auditory Perception

Auditory 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...
