摘要

作为调幅的声包线包含了语音可理解性的相关信息。Hewitt和Meddis开发了一个听觉通路模型来编码振幅调制。它被扩展到一个多通道。比较了下丘对调幅白噪声和调幅音的反应在发射频率和同步指数上的差异。载波信号不影响单个特征频率单元。这个结果让我们提出一个更完整的结构有待探索。

Détection de la modulation d'amplitude au niveau du colliculus inférieur : influence du signal porteur

Sound envelope considered as amplitude modulation contains relevant information about speech intelligibility. Hewitt and Meddis developed an auditory pathway model that codes amplitude modulation. It was extended to a multi channel one. Inferior colliculus response to amplitude-modulated white noise is compared with the response to amplitude-modulated tone in terms of firing rate and synchronisation index. The carrier signal does not affect single characteristic frequency unit. This result lets us propose a more complete structure to be explored.
