Key statistics
- People use background music for about 39% of their reading time and 24% of their memorizing time.
- Across 97 studies, background music has no overall effect but consistently hurts reading comprehension.
- Lyrics lower memory and reading performance (d ≈ −0.3). Instrumental music shows no credible effect.
- Background speech starts hurting performance at a Speech Transmission Index of just 0.21.
- White and pink noise help people with ADHD a little and hurt everyone else a little.
- Only 5 of 14 EEG studies support the idea that binaural beats entrain brainwaves.
- Attention on one screen has dropped from 2.5 minutes (2004) to 47 seconds.
Usage
How often people use music while they work
In a survey of 140 people, participants used background music for about 43% of their writing time, 39% of their reading time and 24% of their memorizing time, and used less of it as tasks got harder (Goltz & Sadakata, 2021).
Background music is a habit, not an edge case. Participants in this survey reported how much of their time on four everyday tasks they spend with music playing. Usage varied enormously between people: 46 said they use music less than 10% of the time while reading, while 6 said they always do.
The pattern across people is clear, though. Music use drops as tasks get more demanding, people become pickier about what they play, and the preferred choices are calm, classical and non-vocal music. Younger participants used more background music than older ones.

Meta-analysis
Does background music help or hurt?
A meta-analysis of 97 studies found no overall effect of background music (r = +.03), but music hurt reading comprehension in all 8 reading studies (r = −.11) and slightly hurt memory (r = −.09) (Kämpfe et al., 2011).
The largest meta-analysis on the question started with 189 articles and could include 97 studies with enough data to compute effect sizes. Taken together, background music had essentially no effect. The authors argue that this null result comes from averaging opposite effects, not from music doing nothing.
Split by task, the picture sharpens. Music gave a small lift to sports performance and emotional reactions. It slightly impaired memory tasks. And in every one of the eight reading studies, music hurt text comprehension.

Lyrics
Lyrics vs instrumental music
Music with lyrics lowered verbal memory, visual memory and reading comprehension compared with silence (d ≈ −0.3), while instrumental lo-fi music had no credible effect on any task (Souza & Leal Barbosa, 2023).
Lyrics are the clearest single driver of distraction in recent studies. In a 2023 experiment, college students did verbal memory, visual memory, reading comprehension and arithmetic tasks in silence, with instrumental hip-hop lo-fi, and with music that had lyrics. Lyrics hurt the first three tasks. The instrumental track did not credibly help or hurt anything.
The participants noticed the cost of lyrics themselves. They did not notice that instrumental music was neutral rather than helpful: some rated it as beneficial.
A separate set of four reading experiments reached the same conclusion from a different angle. Instrumental versions of songs either left reading speed unchanged or made it slightly faster, while the same songs with lyrics slowed reading in three of the four experiments. The authors describe the lyric effect as real but mild.

Office noise
How much background speech it takes to hurt performance
Across 14 laboratory studies (34 tests), cognitive performance starts to fall once background speech passes a Speech Transmission Index of about 0.21 and reaches its full decline by 0.44, long before speech is perfectly clear (Haapakangas et al., 2020).
The Speech Transmission Index (STI) measures how intelligible speech is, from 0 (you cannot make out words) to 1 (perfectly clear). A 2020 review of 14 laboratory studies revised the standard model of how intelligible background speech affects work.
Performance begins to decline at an STI of about 0.21 and hits its maximum decline by 0.44. In other words, speech does not need to be fully understandable to cost you: half-heard conversation is already at the maximum. Verbal short-term memory tasks were the most strongly and consistently affected, declining between STI 0.12 and 0.51.

Noise and ADHD
White and pink noise for ADHD
White and pink noise gave a small benefit to young people with ADHD (g = 0.249, 13 studies, 335 participants) and a small harm to people without ADHD (g = −0.212). No studies of brown noise were found (Nigg et al., 2024).
A 2024 meta-analysis pooled randomized laboratory studies of children and college-age young adults with ADHD or elevated ADHD symptoms. White and pink noise produced a small, statistically significant improvement on attention tasks, with minimal variation between studies and no sign of publication bias.
The same noise worked in the opposite direction for comparison groups without ADHD, where it made performance slightly worse. The review also searched for brown noise studies and found none, despite brown noise being the most talked about of the three online.
Averages hide a split. In a 2024 study of 43 children with a clinical ADHD diagnosis, noise had no significant effect across the whole group. Children with more inattentive traits did better with noise, while those with more hyperactive and impulsive traits did worse, and about one third of the sample performed worse under noise.

Binaural beats
Do binaural beats change brainwaves?
Of 14 EEG studies on binaural beats, 5 supported the brainwave entrainment hypothesis, 8 contradicted it and 1 was mixed (Ingendoh et al., 2023).
Binaural beats play a slightly different tone in each ear, and the brain perceives a third tone at the difference frequency. The popular claim is that this pulls brain activity toward that frequency, known as the brainwave entrainment hypothesis.
A 2023 systematic review looked at every study that measured this directly with EEG. The results split, and more studies contradicted the hypothesis than supported it. The reviewers also note that the studies differed so much in method that they are hard to compare at all.

Attention
How long attention lasts on a screen
Average attention on a single screen fell from about 2.5 minutes in 2004 to 75 seconds in 2012 and 47 seconds in recent years, with a median of 40 seconds (Gloria Mark, 2023).
Gloria Mark, a professor of informatics at UC Irvine, has tracked how long office workers stay on one screen before switching since 2004, by observing and logging real computer use rather than asking people to estimate it.
These figures come from Mark's own summary of her research program in a 2023 University of California interview, which accompanies her book Attention Span. They are averages across different studies and samples, not one repeated experiment.

Method
How these numbers were checked
Each statistic was checked against the paper's full text or the publisher's abstract, not against another article quoting it. Several widely repeated figures did not survive that check and are left out on purpose:
- "It takes 23 minutes to refocus after an interruption." We could not find this number in the published papers it is usually attributed to.
- Commissioned surveys claiming music makes most workers more accurate or faster. These are marketing studies without published methods.
- Claims that lyrics are exactly as distracting as someone talking. The published abstracts we checked do not state this.
Takeaways
What the research suggests for focus audio
Three things show up consistently. Words in your ears cost you, whether they come from a song or a nearby conversation. Instrumental audio is mostly neutral, not a performance booster. And noise helps some brains while slightly hurting others, so personal response matters more than any one sound color.
That is why Underlay.fm builds sessions from pure texture: layered noise and tuned tones with no lyrics, melody or beat. It is designed to mask speech and sit in the background, not to claim a boost the research does not support.
Common questions
Does listening to music help you focus?+
On average, not much either way. The largest meta-analysis on the topic (97 studies) found no overall effect, but it found consistent harm for reading comprehension and a small cost for memory. Whether music helps depends heavily on the task and on the music, especially whether it has lyrics.
Is instrumental music better than music with lyrics for studying?+
Yes, according to the current evidence. In a 2023 study, music with lyrics lowered verbal memory, visual memory and reading comprehension, while instrumental lo-fi had no credible effect. Another 2023 study across four experiments found instrumental music did not slow reading, while lyrics slowed it in three of the four.
Does white noise help with ADHD?+
A little, for some people. A 2024 meta-analysis found a small benefit for young people with ADHD (g = 0.249) and a small harm for people without ADHD. A separate 2024 study of 43 children with clinical ADHD found about one third performed worse with noise, especially those with more hyperactive and impulsive traits.
Is there research on brown noise for focus?+
Very little. The 2024 meta-analysis on noise and ADHD searched for brown noise studies and found none that met its criteria. Brown noise is popular, but the controlled evidence so far is for white and pink noise.
Do binaural beats work?+
The evidence is inconsistent. A 2023 systematic review of 14 EEG studies found 5 that supported brainwave entrainment and 8 that contradicted it, with methods too varied to compare cleanly.
Can I use these statistics in my own article?+
Yes. Each statistic has its own link and a copy citation button. Please cite the original study as well; the full reference for each one is in the sources list at the bottom of this page.
