Central Auditory Processing

When objects vibrate, they transmit acoustic energy in the form of a wave. Our ears measure this sound energy and transmit it to the brain. The task of the brain is to interpret this signal and create the perception of sound and speech. 

The Eaton-Peabody Laboratories are home to several research groups that seek to understand how the activity of nerve cells in auditory processing centers of the brain encode signals from normal ears, damaged ears, and next-generation neuroprosthetic devices. 

Our work is probing the limits of plasticity in both developing and adult brains to understand how speech intelligibility can be further enhanced, and how debilitating perceptual disorders such as tinnitus and hyperacusis can be minimized or eliminated altogether.
