The Discrimination of PB-K in Noise (PBKN) test is often considered an auditory processing disorder test.

There are five 25-word lists; two are in quiet, and the remaining three are imbedded in white noise at a signal-to-noise ration of 0 dB. Part of the test is presented through earphones and part through a loudspeaker. A sound-treated room is not required. The PBKN was standardized on children from kindergarten through the fifth grade.
