Silencers refine sound localization

A new study by LMU researchers shows that sound localization involves a complex interplay between excitatory and inhibitory signals. Pinpointing of sound sources in space would be impossible without the tuning effect of the ...

Feedback loops and localization errors

Neurobiologists at Ludwig Maximilian University of Munich describe a feedback loop that modulates the processing of auditory signals in the brainstem in a frequency-dependent manner, and can lead to systematic errors in the ...

Two bionic ears are better than the sum of their parts

Cochlear implants—electronic devices surgically implanted in the ear to help provide a sense of sound—have been successfully used since the late 1980's. But questions remain as to whether bilateral cochlear implants, ...
