Neural representations (ITD alone, activities due to ILD and envelope cues excluded) of ocean waves rolling on a beach recorded using the Neumann KU100 dummy head. Saint Augustine Beach, Florida, December 28, 2016. 

Maximal activities mainly encode directions corresponding to the most ipsilaterally ‘tuned’ neurons, especially at frequencies below ~400 Hz. Maximal representations therefore mostly reflect the extent to which neurons are selective for ipsilateral interaural phase differences (IPD, ±0.03 cycles) as opposed to IPDs present in the binaural recordings.
