Short answers to the questions people actually ask. Each one links to the page that works it through properly — the answer here is the summary, not the argument.
Do binaural beats actually work?
They reliably produce a perceived pulse when different tones reach each ear separately. Whether that produces a useful change in focus, sleep or mood is unsettled: research is mixed and most studies are small. Read what the evidence says about binaural beats for the reviews and studies with their sample sizes and stated limitations.
Are binaural beats safe?
For most people it is ordinary headphone audio, so the cautions are the ordinary ones: volume, session length, and not wearing headphones where you need to hear your surroundings. Two narrower cautions — the epilepsy one, and existing ear or hearing conditions — are set out with their reasoning on are binaural beats safe.
Do I need headphones?
Yes, because each ear has to receive its own tone. See do you need headphones for binaural beats for what preserves that separation and what quietly destroys it, including mono audio settings and headsets that switch to a call profile.
How loud should it be, and how long should a session run?
Quiet enough to be background, and as long as the activity you started it for — no study establishes a correct volume or duration. See how to listen to binaural beats for the practice, including what “it is not working” usually turns out to mean.
What is the difference between binaural, monaural and isochronic beats?
Where the pulse is created: in your hearing, in the signal, or by switching a single tone on and off. Only the first needs headphones. See binaural, monaural and isochronic beats.
Which frequency should I use?
There is no evidence-based way to choose one, and the popular lists mix up two different numbers. See binaural beat frequencies for where the 432 Hz and 528 Hz claims come from and what the research does not establish.
Can I use binaural beats for focus?
You can, as an option to try rather than a promise: the research does not establish a fixed focus result or an app-specific outcome. See how to use binaural beats for focus for the practical routine — when in a work block to start one, how long to run it, and what to do when it does not help.
What about a bedtime routine?
People do use audio that way, and it is a personal choice. The research does not establish a reliable time to fall asleep, and the sleep studies with what each one measured are on the evidence page. If sleep or anxiety problems keep happening or interfere with daily life, talk with a licensed clinician.
