Frequently Asked Questions
Everything you need to know about Entrainium and brainwave entrainment. From getting started to advanced usage.
Getting Started
Entrainium is a premium brainwave wellness app that uses scientifically-inspired audio frequencies to help guide your mental state. Through binaural beats, monaural beats, and isochronic tones, we offer curated sessions for relaxation, focus, sleep, and energy.
Your brain naturally produces electrical patterns at different frequencies. Entrainium uses gentle audio stimulation to encourage your brain toward specific states associated with different mental experiences. Each session features organic frequency wobbles that mimic natural brainwave variability for a more effective, comfortable experience.

This is our signature innovation that sets Entrainium apart from other apps. Here's why wobbles are scientifically superior:
๐ง Natural Brain Behavior
Your brain's natural oscillations are never perfectly static. Real brainwaves vary continuously around a center frequency โ a 6 Hz theta wave naturally fluctuates between ~5.5-6.5 Hz. Research by Klimesch (1999) and Baลar (2012) shows that natural EEG rhythms exhibit inherent frequency variability, not rigid static frequencies.

Research by Klimesch (1999) and Baลar (2012) shows that natural EEG rhythms exhibit inherent frequency variability, not rigid static frequencies.
โก Preventing Habituation
Static frequencies cause neural habituation โ your brain stops responding after prolonged exposure. Studies on auditory steady-state responses (Ross et al., 2000) demonstrate that constant stimulation leads to decreased neural response over time. Our organic wobbles prevent this by continuously engaging fresh neural populations.

๐ฏ Enhanced Entrainment
Variable frequencies create a "frequency following response" across a bandwidth rather than a single point. Research by Schwarz & Taylor (2005) on auditory driving suggests that frequency-modulated stimuli may produce more robust entrainment than static tones. The brain naturally "locks on" better when the target moves organically.
What other apps do wrong: Most binaural apps use rigid, computer-perfect static frequencies (exactly 6.000000 Hz). This is unnatural and less effective. Our wobbles (5.25-6.75 Hz) mimic how real brainwaves behave, creating a gentler, more sustainable entrainment effect.

Because music significantly reduces or eliminates the binaural effect. This is backed by science and a critical distinction:
๐ซ The Music Problem
For binaural beats to work, your brain must clearly perceive BOTH pure tones (one in each ear) to calculate their difference frequency. When you add music:
For binaural beats to work, your brain must clearly perceive BOTH pure tones (one in each ear) to calculate their difference frequency. When you add music:
- Frequency masking: Music contains hundreds of frequencies that mask the pure carrier tones
- Attention hijacking: Your brain focuses on melody, lyrics, and rhythm instead of the subtle beat frequency
- Neural interference: Complex musical stimuli activate different brain regions, competing with entrainment pathways
๐ Research Evidence
Wahbeh et al. (2007) and Chaieb et al. (2015) used pure tones in their controlled studies โ not music. Garcia-Argibay's 2019 meta-analysis of 22 studies found that research using isolated binaural beats showed measurable effects, while studies mixing beats with complex audio showed inconsistent results.
Oster's foundational 1973 paper in Scientific American emphasized that binaural beats require "two pure tones" with minimal auditory complexity for the brain to generate the phantom beat.

๐ฏ The Entrainium Advantage
We provide clinical-grade purity:
Bottom line: Apps that layer binaural beats under music are essentially playing relaxing music โ the binaural effect is minimal or absent. If you want actual entrainment backed by science, you need pure tones. We offer optional pink noise for ambience without compromising effectiveness.
We provide clinical-grade purity:
- Pure sine wave carriers (not masked by music)
- Optional pink noise (scientifically balanced, doesn't mask frequencies)
- Precise frequency control for true entrainment
- Professional audio synthesis matching research protocols

Entrainium is built for clinical-grade effectiveness, not just relaxation. Here's what separates us from "binaural music" apps:
โ
1. Research-Grade Purity
We use pure sine wave synthesis matching laboratory protocols โ the same methodology used in peer-reviewed studies. Most apps layer beats under music, which research shows is ineffective for true entrainment.

2. Organic Frequency Wobbles
Our proprietary wobble algorithm mimics natural brainwave variability (ยฑ0.5-4 Hz around center), preventing habituation and enhancing entrainment. Other apps use rigid computer-perfect frequencies that your brain learns to ignore.

If you want relaxing background music โ plenty of apps do that well.
If you want actual brainwave entrainment backed by science โ Entrainium is your answer.
Each session shows its recommended duration (8-45 minutes). Start with shorter sessions and gradually increase as you get comfortable.
- Gentle sessions: 15-20 min
- Moderate sessions: 20-30 min
- Deep sessions: 30-45 min
Keep it low and comfortable โ around 20-40% to start. You should barely notice the tones. The effect works at low volumes, and too much volume can be uncomfortable or less effective.

Pink noise is a soothing background sound (like gentle rain or wind) that masks distractions and creates a cocoon of calm. It's scientifically balanced across frequencies for maximum comfort. Try it at 30-50% for a spa-like atmosphere.
FM Depth adds a gentle frequency vibrato โ like a singer's natural voice wobble or a theremin sound. At higher settings (50-100 Hz), it creates a rich, organic quality that some users find more engaging than pure tones. Experiment to find what feels best!
Safety & Best Practices
For most people, yes โ when used responsibly. However:
- DO NOT use if you have epilepsy, seizure disorders, or similar conditions
- DO NOT use while driving, operating machinery, or doing anything requiring full attention
- Start with low volume and short sessions (10-15 minutes)
- Stop immediately if you feel dizzy, nauseous, or uncomfortable
- Consult your doctor if you have any medical or psychiatric conditions
Yes, daily use is fine for most people. Many users make it part of their daily wellness routine. However:
- Give yourself breaks if you feel oversaturated
- Vary your sessions rather than using the same one repeatedly
- If you notice diminishing effects, take a few days off
- This tool complements โ not replaces โ healthy sleep, exercise, and stress management
No. Entrainium is a wellness tool, not a substance. It won't create physical dependence. However, like meditation or exercise, it works best as part of a balanced lifestyle. Don't use it to avoid addressing underlying health issues โ always consult professionals for medical concerns.
Technical Questions
No โ Entrainium is a web app that requires an internet connection to load. Once loaded, all audio generation happens in your browser, but you need to stay connected. For offline use, consider a native app from your device's app store.
Yes! Modern Bluetooth (aptX, AAC, LDAC) preserves enough quality for effective entrainment. While purists prefer wired for maximum fidelity, the most important factors are comfort and consistent use. Use what feels best to you.
On mobile devices, we automatically optimize carrier frequencies for smaller speakers (except for Solfeggio and Schumann frequencies, which maintain their precise tuning). This is intentional and improves the experience. For the most accurate frequency reproduction, use headphones on any device.
