Frequently Asked Questions (FAQ)

What is white noise and how does it work?

White noise is a type of sound that contains all audible frequencies at equal intensity. Think of it like white light, which contains all colors of the visible spectrum. This consistent sound masks other noises by providing a steady audio backdrop that your brain can tune out. White noise works by reducing the difference between background sounds and sudden noises, making environmental sounds less noticeable and startling. This is why it's so effective for focus, sleep, and noise masking.

Are binaural beats safe to use?

Yes, binaural beats are completely safe for most people when used as directed. They've been studied extensively since their discovery in 1839 and are used in clinical settings for stress reduction, pain management, and improved cognitive performance. However, people with epilepsy, seizure disorders, or who are pregnant should consult a healthcare provider before using binaural beats, as there have been isolated reports of seizures triggered by certain audio frequencies. Always use binaural beats at comfortable volumes.

Do I need headphones for white noise?

No, headphones are not required for white noise, pink noise, or brown noise. These sounds work well through any speaker system. However, headphones ARE REQUIRED for binaural beats to work properly. Binaural beats rely on sending slightly different frequencies to each ear separately, which creates the perceived "beat" frequency in your brain. This effect cannot occur with speakers where both ears hear both frequencies.

What's the difference between white, pink, and brown noise?

The difference lies in their frequency distribution:

White Noise: Contains all frequencies at equal power, creating a "hissing" sound similar to TV static or a fan. Best for general noise masking and focus.

Pink Noise: Has more power in lower frequencies, making it deeper and softer than white noise. Sounds like steady rainfall or rustling leaves. Best for sleep and relaxation.

Brown Noise: Emphasizes even lower frequencies, producing a deep rumbling like a waterfall or strong wind. Best for meditation, anxiety relief, and ADHD focus.

Many people find pink and brown noise more pleasant and natural-sounding than white noise, but preference is highly individual.

What frequency is best for studying and focus?

For studying and intense focus, use either brown noise or binaural beats in the beta wave range (14-30 Hz). Our preset "Focus Mode" uses 14 Hz, which is ideal for concentration, alertness, and cognitive performance. Beta waves are associated with active thinking, problem-solving, and focused attention. For optimal results, use brown noise or 14 Hz binaural beats for 25-50 minute study blocks, followed by 5-10 minute breaks. This aligns with the Pomodoro Technique for maximum productivity.

How long should I listen to binaural beats?

Most people benefit from 15-30 minute sessions of binaural beats. It typically takes 5-10 minutes for your brainwaves to begin synchronizing with the beat frequency (a process called entrainment). For sleep, you can listen for 30-60 minutes or until you fall asleep. For meditation and relaxation, 20-30 minutes is ideal. For focus and study, you can listen continuously during your work session. Start with shorter sessions (10-15 minutes) and gradually increase as you become comfortable with the effects.

Can I use this tool every day?

Yes! Daily use is not only safe but encouraged. Consistent use of white noise, pink noise, brown noise, and binaural beats builds cumulative benefits over time. Many users report that effects become more pronounced with regular practice as their brain becomes more responsive to the frequencies. Our built-in streak tracker is specifically designed to encourage daily use. Try to use the tool for at least 10-15 minutes every day to establish a healthy habit and maximize benefits.

Will this work on my phone/tablet?

Yes! Our sound generator is fully responsive and works perfectly on smartphones, tablets, laptops, and desktop computers. The interface automatically adapts to your screen size. For the best experience with binaural beats on mobile devices, use quality headphones or earbuds. The tool works in all modern web browsers including Chrome, Firefox, Safari, and Edge. No app download is required - simply access it through your web browser.

Why isn't the sound playing?

If you're not hearing any sound, check these common issues:
1. Make sure your device volume is turned up (both system volume and browser volume)
2. Check that your browser isn't muted (look for a speaker icon on the browser tab)
3. Some browsers require user interaction before playing audio - make sure you've clicked the "Play" button
4. Check that headphones/speakers are properly connected
5. Try refreshing the page
6. Ensure your browser supports Web Audio API (all modern browsers do)
If problems persist, try using a different browser.

Can white noise damage my hearing?

White noise and other generated sounds in our tool are safe when used at appropriate volumes. Follow the 60/60 rule: listen at no more than 60% volume for no more than 60 minutes at a time without a break. If you need to raise your voice to speak over the sound, it's too loud. For sleep, keep the volume just loud enough to mask disturbing sounds but not so loud that it becomes the focus. Prolonged exposure to loud sounds (above 85 decibels) can damage hearing, but at comfortable volumes, white noise and binaural beats pose no risk.

Is this really free? Are there hidden costs?

Yes, this tool is 100% free with no hidden costs, subscriptions, or premium tiers. We don't require credit cards, email signups, or any personal information. Our goal is to make sound therapy accessible to everyone who needs it. The tool runs entirely in your web browser with no server costs for audio generation. You can use it as many times as you want, for as long as you want, completely free. Forever.

How does the streak tracker work?

Our streak tracker counts consecutive days you've used the sound generator. If you use the tool at least once per day, your streak increases. If you skip a day, the streak resets to 1 the next time you use it. The streak is saved in your browser's local storage, so it persists even if you close the browser or shut down your device. Building a streak creates positive motivation and helps establish a consistent sound therapy practice. Many users report that maintaining their streak helps them build healthy daily habits for focus, meditation, or better sleep.

Can I use this for my baby or child?

White noise, pink noise, and brown noise are safe for babies and children when used at appropriate volumes. White noise is particularly popular for infant sleep because it mimics the sounds babies heard in the womb. Keep the volume low - about the volume of a soft shower running - and place the device at least 7 feet away from the baby's crib. However, we do NOT recommend using binaural beats for children under 18 without consulting a pediatrician first, as research on developing brains is limited. Stick with white, pink, or brown noise for young children.
