Is Silence Golden? How Office Noise Affects Productivity

Is Silence Golden? How Office Noise Affects Productivity

We analyse the relationship between sound and productivity. Learn about office noise recommendations, whether noise impacts creativity, and which music genres can boost productivity.

Ahh the familiar tinny sound of Christina Aguilera’s ‘Dirrty’ escapes my co-worker’s headphones for the second time today. It got me thinking. Can ambient background noise actually make your office a more productive environment?

In this article we take a look at the different types of ‘office noise’, what effects they have on our cognitive ability (using real life sciencey stuff), and how different types of jobs may be better suited to ambient noise more than others … 

The sound of silence

Not every subheading will be named after a Simon & Garfunkel masterpiece, so enjoy that one. It is a common belief that we need absolute silence to maximise concentration. This is ingrained into us as children – for every test we’ve ever sat, or every exam we’ve ever failed, we’ve been in total silence. 

Just you, the ticking clock, and the squeaky soles of a hawk-eyed invigilator.

Depending on the task, it is true that your brain can function better when surrounding noise is reduced. How many of you turn the music down in your car as you approach a roundabout? You don’t do it so that you can see the cars coming, you do it so you can focus on the BMW that isn’t indicating.

“The Wrong Sound Environment makes you 66% Less Productive” – Noisili.

The scientific reason for this is that we require at least two of our senses to deliver an optimum response to any given stimulus. When we eat, we want to see what the food looks like before we taste it. When we go to the cinema, we need to hear as well as see the film.

Unless it’s a silent film … Charlie Chaplin aside, you get my point.

When it comes to working in an office environment though, sometimes surrounding noise simply cannot be avoided. From outbound calls to the tap, tap, tapping of keyboards, it’s pretty much impossible to exist in a totally silent office.

But would you want to?

Office noise levels recommendations

As I type this, the paper shredder has become jammed and is now making an unsettling churning sound. What’s worse is that there is a car alarm going off outside, and it has been for 20 minutes now. If someone is trying to steal it, why don’t they do us all a favour and just hurry up?

Admittedly the car alarm isn’t technically an office noise or something within our control.

This song features a total of 1,560 words in just 6 minutes and 4 seconds. Not ideal for peak concentration in the office.

If you’re reading this article in your office right now, just have a think for a second about all of the noises you can hear. Would you consider it acceptable? Are you able to work consistently without distraction? Check out the sound chart below to see how office noise compares with other noise levels we experience on a daily basis … 

Here’s why a loud office cultivates productivity

To use a widely know quote, silence can be deafening. By this I mean that complete silence can cause your brain to enter meltdown and your creativity to pack up and leave. In literary terms, silence is a lot like writer’s block; a phenomenon where the vast white space becomes daunting and off-putting … 

Not nice is it?

This is where ambient sound comes in. Ambient sound is basically a posh term for ‘background’ noise – covering anything from water running, birds singing or leaves rustling. Our minds are hardwired to live amongst ambient noise (because … nature), meaning that a totally silent dwelling seems odd and unpleasant.

Even if you crave ‘peace and quiet’ after putting the kids to bed, you rarely experience actual quiet unless you’re going to sleep. The TV may be on, music could be playing, your husband may be snoring – never silent. Even the hum of a refrigerator registers around 39 decibels.

So why, when the only silence we get is at bedtime, is it a common belief that a productive office should hear a pin drop? That’s how we fall asleep at work folks – just ask this guy.

The 1883 Krakatoa explosion registered 172 decibels at 100 miles from the source. This is so astonishingly loud, that it’s inching up against the limits of what we mean by ‘sound.’

A study published by the Oxford University Press, entitled ‘Is Noise Always Bad? Exploring the Effects of Ambient Noise on Creative Cognition’, found that workers who were exposed to a moderate level of ambient noise creatively and productively outperformed those working in extremity (silent or much louder) environments. Ravi Mehta outlines this below:

“We found that increasing levels of noise induced distraction, leading to a higher construal level. That is, both moderate and high noise levels lead to more abstract processing as compared to a low noise level. This higher construal level then induces greater creativity in the moderate-noise condition.”

Part of Mehta’s experiment measured a group’s creativity in relation to surrounding noise level. They were asked to come up with as many ‘creative uses of a brick‘ as possible, and then judged on their immediate and delayed response times. The graph below shows how background noise affected their performance:

It’s apparent from this test that an increased ambient noise level aided in creativity. Whether this applies to everyone in the whole world is simply intangible, as results will be subjective to every person, but on this occasion it does disprove the old adage of ‘silence being golden.’

Let’s be honest, the sound of a Transylvanian hurricane is much better than the sound of Deborah’s over-zealous typing and Patrick’s insufferable tea-slurping.

Ambient noise apps: the powerpacks to productivity

So you’ve decided that you want a piece of the ambient noise pie, except your boss still isn’t buying it, so productivity-boosting chatter is permitted only at lunchtimes or for a timed maximum of 30 seconds every two hours.
What can you do?

Well fortunately there is an answer. It involves putting some headphones on and losing yourself in the magical world of sound. I’m not just talking music, but ambient noises recorded from nature.

A quick search in the App Store will return tons of ambient noise apps – giving you a wide range of choice when it comes to raindrop noises or leaf crunching. 

Our personal favourite though is Noisili. It can either be downloaded in the App Store or it can be added to a Google Chromebox in just a couple of clicks.

Noisili offers a wide range of pre-recorded scenarios to take your mind on a journey far, far away from the confines of your office – whisking you off to a bustling coffee shop in Soho, a Transylvanian hurricane, or beneath rainfall in a Canadian log cabin.

Though you might crave the gravelly tones of Otis Redding or the smooth silk of Sade, it’s worth considering what genre of music best suits a thinking brain.

Let’s be honest, the sound of a Transylvanian hurricane is much better than the sound of Deborah’s over-zealous typing and Patrick’s insufferable tea-slurping.
Hold on a second though.

You’re going to need headphones for this. And the last thing you want is loud typing and paper shredders spoiling your ambient whale conversations.

Noise cancelling vs. noise isolating headphones

There are two types we’re interested in here and most people get them confused (for good reason). There are noise cancelling headphones and noise isolating ones. Both ultimately have the end goal of muting any external noises (like Karen’s USB desk fan for example), but both achieve the results differently.

To save the article from becoming too heavy on headphone witchcraft, I’ll just keep it simple:

Noise cancelling – uses inverse wave technology to counteract external sound.
Noise isolating – attempt to put a physical barrier between your ear and external sound.

Which is best for the office?

For the average office environment, noise isolating will do just fine. While noise cancelling headphones would do just as good a job, they are made more for traveling and dealing with constant droning sounds (which can sometimes occur in the office, can’t they Karen?!). This just means you’re paying more for the noise cancelling technology when you just don’t need it.

As a premium pair of headphones for office use, the Bose QuietComfort 20 are an excellent all-round choice. They’re discreet, high quality and will bat away any excessive office babble.

If you don’t fancy taking a mortgage out and selling your first born’s soul for some headphones, then there are some cheaper but very competent alternatives on this list.

Hats off to you, if you listen to this during working hours without doing the silly dance then you win at this thing called life.

Which genres of music feed productivity the most?

There’s going to be times when you want to listen to more than just rustling leaves on your new office headphones. And though you might crave the gravelly tones of Otis Redding or the smooth silk of Sade, it’s worth considering what genre of music best suits a thinking brain.
Best vs. worst music genres for boosting productivity

The University of Birmingham investigated the relationship between the playing of background music during the performance of repetitive work and efficiency in performing such a task. 

“Music is organised sound.” – Edgard Varese.

The studies revealed that workers experienced an overall rise in efficiency and productivity when they were exposed to music. But what type of music should we listen to?

Using the stats produced from extensive research by Heriot-Watt University, we’ve created an infographic which shows what musical genres can say about your personality type AND how productive they make you. Check it out:

As an extension of the graphic above, here’s a list of three of the most inappropriate songs to work to. Supporting the information above, two of the three songs listed below fall into the Metal and Rap genres – considered the least productive of them all.

Top 3 most inappropriate songs to work to:

1. Rap God by Eminem. This song features a total of 1,560 words in just 6 minutes and 4 seconds. Not ideal for peak concentration in the office.

2. Chop Suey! by System of a Down. This is pretty heavy stuff that will not assist spreadsheet making or document filing in anyway.

3. Gangnam Style by Psy. Hats off to you, if you listen to this during working hours without doing the silly dance then you win at this thing called life.


At the end of the day, everyone works at various tempos and thrives in different ways. Just because we say rap music is distracting, or that total silence is a bad thing, doesn’t mean that it’ll suit you. It helps to try out different things when you’re working, so you can find your ‘happy place’. 

Try your music at different volumes, try using an ambient noise app, try total silence. Whatever works best for you. Chances are if you deal with numbers or spreadsheets for most of the day, then lyrics will prove interfering; but if you write creatively then the words to a song could just be the spark of inspiration you needed!

Ultimately, the industry you work within will decide what noise level will help you thrive.
