Most of us have two ears. It is a wonderful system that allows us to hear sounds spatially, and to communicate effectively in noisy surroundings. The only thing missing is an earlid. Don't you sometimes wish you could just close one ear? I am fascinated by how the brain reads out and assembles information from its two acoustic sensors. Binaural Hearing : How is information combined across the two ears? Auditory Spatial Attention: How does attention to auditory spatial features affect speech intelligibility? Spatial Hearing : How do human listeners localize sound in reverberant rooms?
