Welcome to random Wiki of the Day where we read the summary of a random Wikipedia page every day.

The random article for Tuesday, 23 April 2019 is Dichotic pitch.

Dichotic Pitch or the Dichotic Pitch Phenomenon occurs when two signals, which are the same in several respects except for one, are presented to the two ears. A variation of this includes the Huggins Pitch, which produces two white-noise signals that only differ in the interaural phase relation over a narrow range of frequencies. For humans, this phenomenon is restricted to fundamental frequencies lower than 330 Hz and extremely low sound pressure levels. Experts investigate the effects of the dichotic pitch on the brain. For instance, there are studies that suggested it evokes activation at the lateral end of Heschl's gyrus.

This recording reflects the Wikipedia text as of 01:13 UTC on Tuesday, 23 April 2019.
