An Empirical Investigation Into the Effect of Beta Frequency Binaural-beat Audio Signals on Four Measures of Human Memory

In a study from 1994, Richard Kennerly wrote about the observable effects on memory:

Beta frequency binaural-beat audio signals were utilized to investigate facilitation of human performance on two memory tasks and two memory related tasks. Subjects were 50 college students randomly assigned with a double-blind methodology to the control or experimental groups. The control group listened to instrumental music. The experimental group listened to the same music with binaural-beat audio signals bedded under the music. The four dependent variables used were a 25 item word list recall test, a 25 item word list recall/recognition test, and from the WAIS-R the digit symbol and digit span subtests. The experimental group displayed statistically significant (p>.05) increases in mean scores with the word list recall test, the digit symbol subtest, and the digit span subtest. No statistically significant increases in the experimental mean over the control mean were noted in the word list recognition/recall subtest. The results indicate that beta frequency binaural-beat audio signals are an effective method for facilitating simple free recall memory, ability to attend, and the ability to persevere at routine motor tasks.
