Sleep Binaural Beats for Sleep: How They Work and How to Use Them What happens when each ear hears a slightly different tone, what a delta-labelled track is really named after, and a three-step evening routine — with the evidence stated honestly rather than promised. 8 min read Focus Focus music vs. lo-fi: what actually works? Lo-fi, engineered focus music and binaural beats compared against what background-music research actually reports — a global null, a reliable penalty for lyrics, and how to test the question on your own work. 6 min read Science How sound changes your brainwaves A plain-English account of what a brainwave band is, what the auditory steady-state response actually demonstrates, and the gap between a brain responding to a rhythm and a brain adopting a state. 7 min read Sleep Delta waves explained: the sound of deep sleep What delta activity is, how sleep scoring actually defines deep sleep, how much of a night it occupies — and why a delta-labelled audio track is named after the band rather than made of it. 5 min read Sleep Theta waves explained: the edge of sleep Theta is 4–7.99 Hz on the AASM scoring manual, it defines stage N1, and it is below the floor of human hearing — which is why a theta track is named after a subtraction rather than made of theta. 6 min read Relax Alpha waves explained: the resting rhythm Alpha is 8–13 Hz, lives over the occipital lobes, and disappears the moment you open your eyes — the most useful fact about it, and the one alpha audio never mentions. 6 min read Focus Beta waves explained: focus, and where it tips into stress Beta is above 13 Hz and gets sold both ways — the rhythm of concentration and the rhythm of anxiety. A review of 184 studies explains why lowering it is not a coherent goal. 6 min read Science Gamma waves explained: what the 40 Hz research shows The 40 Hz Alzheimer's trials are real and they are tiny — 15 patients in the randomised pilot, five in the two-year extension with no control arm. In healthy adults, the memory studies came back null. 7 min read ADHD Music for ADHD brains: why extra stimulation helps The optimal-stimulation and moderate-brain-arousal accounts of why added background noise helps some attention profiles and hurts others — with the study sizes, the inverted U, and the boundary stated plainly. 6 min read Relax A 10-minute reset for a stressful day Ten minutes, three parts, one of them borrowed from a registered randomised trial of five-minute breathing practices — with what the trial measured, what it did not, and where an ordinary practice ends. 4 min read Focus The Pomodoro + soundscape stack How to pair a 25-minute timer with audio so the sound marks the interval instead of competing with it — including what the break research actually found about performance, which is less than you would hope. 5 min read Focus How to Use Binaural Beats for Focus A practical routine for using binaural beats during work: where in a block to start one, how long to run it, how to pick a track once, and how to read it when nothing changes. 7 min read Science How to Listen to Binaural Beats: Volume, Length, Practice The practice rather than the gear: how loud to set a binaural track, how long a session should run, when to start one, and what it usually means when a session feels like nothing. 7 min read Science Are Binaural Beats Safe? Cautions and Side Effects What is worth being careful about with binaural beats: volume and hearing exposure, situations where headphones are a bad idea, ordinary discomfort, and the epilepsy caution stated plainly. 7 min read Science Do You Need Headphones for Binaural Beats? Binaural beats need each ear to receive its own tone. What that requires, what breaks it — speakers, mono audio, one earbud, a call profile — and which headphone features are marketing. 6 min read Science Binaural Beat Frequencies: What the Claims Leave Out Why frequency lists mix up two different numbers, what the 432 Hz and 528 Hz claims rest on, and why the research does not support choosing a binaural beat by frequency. 6 min read Science Binaural vs Monaural vs Isochronic Beats Where the pulse is created in each of the three — in your hearing, in the signal, or by gating a single tone — why only one of them needs headphones, and what the research does not settle. 5 min read Science Binaural Beats FAQ: Short Answers, With Sources Short, direct answers to the common binaural-beats questions, each pointing to the page that works it through in full: evidence, safety, headphones, listening practice, formats and frequencies. 3 min read Science What Binaura Is Learn what Binaura by PLAY ROCKETS LLC offers on iOS, how binaural beats work, and what the app does not promise. 3 min read Focus How to Use Binaura A walkthrough of the Binaura app: the four moods, subcategories, the player and Neural Level control, and the Library. 3 min read Relax Breathing Exercises Explore a simple, non-medical breathing practice and learn where an ordinary practice ends and clinical care begins. 1 min read
