Binaural Beats — What the Evidence Actually Supports

TL;DR. Binaural beats produce measurable but modest effects on attention and anxiety; most of the consumer-marketing claims overstate what the evidence supports.
What the meta-analyses show
Garcia-Argibay et al.'s 2019 meta-analysis aggregates the binaural-beats literature and finds small-to-moderate effects on attention, memory, and state anxiety. Effects on pain and mood are less consistent.
Most of the dramatic claims in consumer binaural-beats marketing — 'unlock gamma for flow,' 'delta for deep sleep within minutes' — are not supported by this literature.
Relevant research: Garcia-Argibay et al., 2019 (Psychological Research).
Headphones are required
Binaural beats rely on each ear receiving a slightly different frequency, the brain reconciling the difference into a 'beat' at the difference frequency. On speakers this effect doesn't form — you are just hearing two tones.
Loam's binaural presets show a warning badge precisely because the phenomenon is real but the delivery path matters.
Our editorial line
We ship binaural presets because the modest evidence is real and some users find them helpful. We do not market them as state-changing miracles. The {@link /binaural} page describes the frequency bands honestly.
