Cortex auditifalt=Cortex auditifs primaire et secondaire|vignette|Cortex auditif. Le cortex auditif est la partie du cerveau qui analyse les informations auditives, c'est-à-dire les informations extraites des sons par l'ouïe. Il occupe la partie supérieure du lobe temporal. Comme d'autres aires sensorielles, le cortex auditif est organisé hiérarchiquement en aires primaires, secondaires et tertiaires qui sont anatomiquement organisées de façons concentriques dans les parties supérieures et moyennes du lobe temporal : le cortex primaire, localisé au niveau du gyrus de Heschl est entouré des aires secondaires, elles-mêmes encerclées d'aires tertiaires et associatives.

CochleaThe cochlea is the part of the inner ear involved in hearing. It is a spiral-shaped cavity in the bony labyrinth, in humans making 2.75 turns around its axis, the modiolus. A core component of the cochlea is the Organ of Corti, the sensory organ of hearing, which is distributed along the partition separating the fluid chambers in the coiled tapered tube of the cochlea. The name cochlea derives . The cochlea (: cochleae) is a spiraled, hollow, conical chamber of bone, in which waves propagate from the base (near the middle ear and the oval window) to the apex (the top or center of the spiral).
Hearing lossHearing loss is a partial or total inability to hear. Hearing loss may be present at birth or acquired at any time afterwards. Hearing loss may occur in one or both ears. In children, hearing problems can affect the ability to acquire spoken language, and in adults it can create difficulties with social interaction and at work. Hearing loss can be temporary or permanent. Hearing loss related to age usually affects both ears and is due to cochlear hair cell loss. In some people, particularly older people, hearing loss can result in loneliness.
