A steady tone to hold your focus
A low, steady tone can smooth over a noisy room and give your attention something constant to settle into while you work.
Start a focus toneDistraction rarely comes from constant sound. It comes from change: a door closing, a phone buzzing, a conversation starting up. Your brain is wired to notice new sounds, so each interruption pulls your attention off the page. A steady tone fills the gaps with something predictable, so those sudden changes stand out less and you stay in flow longer.
Unlike music, a pure tone has no lyrics, melody, or beat to follow. There is nothing to hum along to or anticipate, which is exactly why some people find it less distracting than a playlist when they are reading or solving problems. ToneSynth's sine wave gives you that smooth, even sound with no harmonic edges.
A continuous tone softens the impact of sudden noises around you.
A pure tone gives your ears something neutral, not a song to follow.
Starting the same tone each session becomes a signal that it is time to work.
The goal is a sound you stop noticing within a minute. Low and quiet works best; a bright, loud tone becomes the distraction you were trying to avoid.
If a single tone feels too plain, the dual-tone mode lets you add a second oscillator a gentle interval away, such as an octave or a fifth, for a slightly richer drone. Keep the second voice quiet so the overall sound stays calm.
No single sound works for everyone, and the research on background sound and focus is genuinely mixed. Treat this as a menu to experiment with.
There is no magic number. Low frequencies, roughly 60 to 200 Hz, tend to sit in the background most comfortably, which is why they work well for masking. Higher tones draw more attention and grow tiring quickly. Start around 100 Hz and adjust to taste.
No. A focus tone is simple sound masking, a steady pitch covering distractions. Binaural beats play slightly different frequencies in each ear to create a perceived pulse, a separate idea with its own mixed evidence. If you want to explore those, a dedicated tool like BinauralHQ handles them.
At a low, comfortable volume, prolonged listening is fine, but follow the 60/60 guideline with headphones: no more than about 60 percent volume for 60 minutes at a stretch, then take a break. If the tone ever feels harsh or tiring, lower the volume or pick a lower frequency.
Music carries lyrics, melody, and rhythm that your brain naturally tracks, and for detailed reading or writing that can compete with the task. A steady tone has none of that structure, so it masks noise without giving your attention something new to follow.
A comfortable pair keeps a focus tone gently in your ears and helps shut out the room during a study block:

Drop the frequency low, keep the volume gentle, and let a steady tone hold the room.
