Aural habilitation7/5/2023 The immediate goals are to provide audibility of the sounds of speech while preserving comfort and perceived sound quality and to do so over as wide a range as possible of talker spectrum, talker distance, talker effort, and interfering noise and reverberation. The basic tools are hearing aids and cochlear implants, with the possible addition of accessories such as FM microphones or assistive devices such as amplified telephones. We address deficits of function through sensory management. 4 In other words, we are currently unable to restore cochlear integrity however, the other 4 areas of deficit can be targets for intervention. 3 At the time of writing, regeneration of hair cells in mammals, once thought to be impossible, has been achieved, but functionality and neural connectivity are still in question it will be many years before we see this work extended to humans. One of the long-term goals of auditory research is to restore cochlear function in humans through the regeneration of functional hair cells along with their neural connections. The goal of aural rehabilitation, as defined here, is to reduce or eliminate these various deficits and, as far as possible, restore the individual to his or her preloss state. Reduced activity impacts participation, and deficits of participation are reflected in quality of life. These last deficits are seriously exacerbated by noise. The deficits of function produce deficits of activity, especially speech perception and communication by spoken language. They may also be compounded by the cognitive and processing difficulties that can accompany aging.Ĭochlear damage has direct and immediate effects on most aspects of auditory function, including sensitivity, resolution, discrimination ability, and noise resistance. Such deficits may, however, be compounded by postsynaptic atrophy and other effects of auditory deprivation. When considering hearing loss, our main anatomic and physiologic concern is cochlear damage, including disruption of structures, malfunction or loss of hair cells, or both.
