1-2-3: The Background Noise That Quietly Shrinks Your Attention Span
sent by Joaquín Kosegarten | October 06, 2026
You like a bit of noise in the background while you work.
The TV humming, a podcast playing, music with lyrics, a busy café in your headphones.
It feels productive. It feels alive.
But there is something happening underneath the surface that’s quietly chipping away at your ability to focus, and you would never know unless someone told you.
1 Idea
Stop working with lyrics, talking, or unpredictable background noise.
2 Ways it saves you time
1. Your brain has limited working memory, and language always takes priority. The moment a podcast voice or song lyric enters your ears, part of your brain starts processing those words, even when you think you are tuning them out. That slows your thinking by 10 to 20%, which means a 60-minute task quietly stretches to 70 or 80 minutes. Switching to silence or instrumental sound saves you that lost time without changing anything else.
2. Unpredictable background noise also forces your brain into constant low-level “what was that?” checks, draining the same attention you need for the work itself. Across a workday, those tiny interruptions accumulate into 30 to 45 minutes of fragmented focus you never quite recover. Steady, predictable sound, or genuine silence, eliminates the drain entirely.
3 Steps to Get It Done:
1. Right now, identify what you usually have playing in the background. Music with lyrics, podcasts, YouTube, the TV? Note which ones show up most.
2. For your next focused work block, swap them for one of these: instrumental music, ambient soundscapes, brown noise, or silence. Test each for a few days and see which feels best.
3. Save your podcasts and lyrical music for low-focus tasks like email, errands, or commutes. Match the soundtrack to the work, not the mood.
Conclusion
You can’t read with one eye and watch TV with the other. The same goes for your ears.
Quieter inputs don’t just feel better. They give you back hours of deep focus you didn’t know you were losing. Try this for one work block today and notice the difference.
This is what the Environment step in Get It Done is built around: shaping your surroundings, including the soundtrack, so your brain can do its best work.
“But I focus better with noise, silence makes me restless”
You might. But there is a difference between feeling productive and being productive. Silence often feels uncomfortable at first because your brain has been trained to expect constant input. Give it 3 days. The restlessness fades, the focus deepens, and you will wonder how you ever worked the other way.
As promised — 1 minute that can save you hours

P.S. Fun Fact: A 2010 study by researchers at the University of Wales found that participants who tried to memorise sequences of numbers while listening to music with lyrics scored noticeably worse than those working in silence, even when they reported “loving” the music. The most surprising twist came from a follow-up: participants who disliked the music actually performed slightly better than those who loved it. The reason? When you enjoy lyrics, your brain pays closer attention to them. Loving your work playlist might be the very reason it’s slowing you down.
