Auditory beat stimulation, cognition and mood: a review (Chaieb 2015)

The review of 30 articles finds that results are frequently contradictory, largely because of heterogeneous stimulation parameters, and calls for standardization.

A plain-language summary from binaural's reading notes, edited by Jude Mc. Last updated 10 November 2026. Not medical advice.

The question: What is known about how monaural and binaural beats affect cognition and mood?

What it found

• Monaural beats are physical and peripheral, demodulated in the cochlea; binaural beats are a subjective percept that needs both ears and is generated centrally in the superior olivary complex from interaural phase differences.
• The auditory steady-state response, an evoked potential that follows the stimulus envelope, is most prominent near 40 Hz and is enhanced under active attention.
• The review surveys effects on attention, memory, vigilance, creativity, mood and anxiety, plus clinical targets such as traumatic brain injury and ADHD.
• Findings are frequently contradictory, largely due to heterogeneous stimulation parameters.

Limits

• Results across studies are frequently contradictory.
• The field needs standardization of stimulation parameters.
• This is a narrative review, although its literature search was PRISMA-guided.
