What Is White Noise?

A conversation between colleagues. A ringing phone. Footsteps in the hallway. The coffee machine running in the background. In a busy workplace, small sounds can quickly become distractions.

White noise is often suggested as a way to make these sounds less noticeable. But what exactly is white noise? Can it help with concentration? And is white noise the same as professional sound masking?

In simple terms, white noise is a continuous sound containing energy across a broad range of frequencies. It can make changes in background sound less noticeable by creating a more consistent sound environment. In professional workplaces, however, specifically designed sound masking is often more appropriate than ordinary white noise.

That difference is important when improving workplace acoustics.

What Is White Noise?

White noise is a continuous broadband sound with energy distributed across a wide range of frequencies. The name comes from white light, which combines different frequencies of visible light.

Many people compare it to the static sound of an old television or radio between stations. A fan or constant airflow can sound somewhat similar, although these sounds are not technically always true white noise.

What makes white noise useful is its consistency.

A sudden conversation or closing door attracts attention because it stands out from the surrounding background. When a continuous background sound is present, the contrast may become less noticeable.

This is where the idea of sound masking becomes relevant.

However, white noise and professional sound masking are not exactly the same thing.

How Does White Noise Work?

Human hearing is particularly sensitive to changes in the surrounding environment.

In a very quiet room, even a small sound can immediately attract attention. Someone starts talking, a keyboard clicks across the room, or a phone vibrates on a nearby desk.

White noise creates a consistent layer of background sound. As a result, certain changes in the acoustic environment may become less noticeable.

It is important to understand that white noise does not remove the original sound.

A conversation is still taking place. The printer is still running. White noise simply changes the background against which those sounds are heard.

This distinction becomes especially important when considering workplace acoustic solutions.

Does White Noise Help With Concentration?

There is no simple answer that applies to everyone.

White noise is sometimes presented as a guaranteed way to improve focus, productivity, or relaxation. In reality, people respond differently to background sound.

Some people find a consistent sound less distracting than an environment filled with sudden changes. Others may find white noise itself distracting or tiring.

The type of work also matters.

Someone writing a detailed report may need a very different acoustic environment from a team that spends much of the day talking and collaborating.

For this reason, white noise should not be treated as a universal solution for concentration problems.

It is better understood as one possible way of influencing the overall sound environment.

Why Is Office Noise So Distracting?

An office does not have to be extremely loud to feel distracting.

Speech can be particularly difficult to ignore. When nearby conversations are clearly understandable, the brain may automatically process parts of what is being said, even when someone is trying to focus on another task.

This is a common challenge in open-plan offices.

Desks may be close together, colleagues hold conversations throughout the day, and video meetings often take place directly at workstations.

The materials within the space also matter.

Glass, concrete, hard flooring, and bare walls reflect sound. In some environments, these reflections allow sound to travel further through the room and can contribute to an uncomfortable acoustic environment.

Good office acoustics are therefore not simply about making a room quieter. They are also about controlling reflections, reverberation, distractions, and speech intelligibility.

White Noise vs Sound Masking: What Is the Difference?

The terms are often used interchangeably, but there is an important difference.

White noise is a specific type of broadband sound with a particular distribution of energy across frequencies.

Sound masking, on the other hand, is a professional acoustic technique. It introduces carefully controlled background sound into a space to make certain sounds, particularly human speech, less noticeable or less intelligible over distance.

A professional sound masking system can be adjusted according to the room, existing background noise, and different workplace zones.

When correctly designed, the result should blend into the background rather than sound like loud static.

For this reason, calling every workplace sound masking system “white noise” is not technically accurate.

In short:

White noise is a type of broadband background sound.

Sound masking is an acoustic technique that uses controlled background sound for a specific purpose, such as reducing the distraction or intelligibility of speech.

Both involve added sound, but their purpose and application are different.

What Are the Benefits of Sound Masking in the Workplace?

When correctly designed and applied, sound masking can form part of a wider workplace acoustic strategy.

Less Distraction From Conversations

A conversation several desks away can sometimes be surprisingly easy to understand.

The intelligibility of speech is often what makes it so distracting.

Sound masking can help reduce the distance over which conversations remain clearly understandable.

Better Speech Privacy

Not every conversation should be easily heard by everyone in the room.

HR discussions, client calls, financial conversations, and meetings between managers and employees may require greater privacy.

Reducing speech intelligibility over distance can support a greater sense of acoustic privacy.

A More Consistent Sound Environment

A workplace that changes from almost silent to suddenly busy can feel distracting.

A carefully controlled background sound can reduce the contrast between quieter periods and sudden sounds, creating a more consistent acoustic environment.

Support for Different Workplace Zones

Modern offices often include spaces for collaboration, individual focus, calls, meetings, and informal conversations.

Each area has different acoustic requirements.

Sound masking can form part of a wider strategy in which the acoustic environment is adapted to the way each space is used.

White, Pink and Brown Noise: What Is the Difference?

White noise is not the only type of coloured noise.

People may also come across pink noise and brown noise. The main difference is how sound energy is distributed across frequencies.

White noise contains relatively more energy in higher frequencies and can sound bright or hiss-like.

Pink noise places relatively more emphasis on lower frequencies, giving it a softer and deeper character.

Brown noise places even greater emphasis on lower frequencies and therefore tends to sound deeper again.

Personal preference plays a role in which sound someone finds most comfortable.

For a professional workplace, however, personal preference alone is not enough to design an acoustic environment. The solution should consider the room, existing noise sources, activities, and required level of speech privacy.

White Noise Is Not the Same as Sound Absorption

This is one of the most important distinctions to understand.

White noise and sound masking add sound to influence how noticeable or intelligible other sounds are.

Sound absorption works differently.

Acoustic materials absorb part of the sound energy that would otherwise reflect from hard surfaces back into the room. This can help control unwanted reflections and reverberation.

Imagine a meeting room with large glass surfaces, a hard floor, and bare walls. Speech reflects from these surfaces, which can make the room sound lively or echoey.

Adding background noise alone does not remove those reflections.

In situations like these, acoustic wall panels or acoustic ceiling panels may be more relevant.

The two principles therefore have different purposes:

Sound absorption helps control reflections and reverberation.

Sound masking influences how noticeable or intelligible certain existing sounds are.

In some workplaces, both approaches can complement each other.

When Are Acoustic Panels a Better Solution?

If reverberation or excessive sound reflection is the main problem, adding sound absorption is often the more logical place to start.

Offices with large areas of glass, concrete, and other hard materials can reflect a considerable amount of sound. Even a relatively small number of people may make the room feel acoustically busy.

Acoustic wall panels add sound-absorbing surfaces to walls while also offering opportunities to complement the interior design.

When wall space is limited because of windows, storage, screens, or other features, acoustic ceiling panels provide another option.

In open workplaces, acoustic partitions can help create more defined working areas.

Closer to individual desks, acoustic desk panels can provide another form of acoustic treatment.

There is no single acoustic product that works best in every situation.

The right solution depends on the room, the source of the problem, and the way sound moves through the space.

Can Acoustic Panels and Sound Masking Work Together?

Yes. The two approaches address different parts of an acoustic problem.

Sound-absorbing materials can help reduce unwanted reflections and control reverberation. Sound masking can then be considered when speech remains too noticeable or intelligible across a workspace.

This combination may be useful in larger open offices where both concentration and communication are important.

However, adding more acoustic material is not automatically better.

An office should support focused work, but people also need to communicate, collaborate, and hold conversations comfortably.

A good acoustic design therefore looks at the complete environment:

• Where does the sound come from?
• Which surfaces reflect it?
• Where are the focus areas?
• Where do people regularly talk or collaborate?
• Which conversations require greater privacy?
• How do employees move through the space?

Only then can the right combination of acoustic solutions be considered.

White Noise When Working From Home

Background noise can also become distracting when working from home.

Traffic passes outside. A refrigerator switches on. Someone speaks in the next room. A neighbour starts work in the garden.

For some people, a consistent background sound can make these changes less noticeable.

But the same principle applies at home as in the office: first identify the actual problem.

Is noise entering from outside? Is the room too reverberant? Is sound travelling from an adjoining room? Or does every small sound stand out because the workspace is extremely quiet?

Each situation may require a different approach.

Anyone who regularly works remotely can therefore consider acoustics alongside ergonomics, lighting, and other elements of a comfortable home workspace.

When Does White Noise Not Solve the Problem?

White noise is not a solution for every acoustic problem.

If a room has strong reverberation, the reflections are still present.

If unwanted sound is travelling through a wall, floor, or ceiling from another room, the problem may require improvements to sound insulation.

White noise can also become a distraction itself when it is too loud or unpleasant for the people using the space.

This is why three commonly confused acoustic concepts should be separated:

Sound absorption helps reduce sound reflections within a room.

Sound insulation helps limit sound transmission between spaces.

Sound masking introduces controlled background sound to make certain existing sounds less noticeable or less intelligible.

These techniques address different acoustic problems and should not be treated as interchangeable.

Good Workplace Acoustics Start With the Problem, Not the Product

White noise is an interesting tool when discussing concentration, privacy, and sound in the workplace. But professional workplace acoustics usually require a broader approach than simply adding a white noise machine.

In one office, excessive reverberation may be the main problem.

In another, conversations may remain understandable over too great a distance. Elsewhere, employees may lack acoustic privacy or collaborative areas may sit too close to quiet work zones.

A good solution therefore starts by understanding the space.

At Akoesta, attention is given to how a room is used, the materials within it, its layout, and the way people work there. From there, suitable acoustic panels, partitions, furniture, or a combination of solutions can be considered.

This makes acoustics part of a comfortable and functional interior rather than an addition made after problems appear.

Frequently Asked Questions About White Noise

What is white noise?

White noise is a continuous broadband sound containing energy across a wide range of frequencies. It is often recognised as a consistent hiss or static-like sound. By creating a continuous background, it can make some changes in surrounding sound less noticeable.

What is white noise used for?

White noise is commonly used to make changing or sudden background sounds less noticeable. Some people use it while working, studying, or relaxing. Its effectiveness and comfort can vary between individuals and environments.

Can white noise help with concentration?

It may help some people, particularly when sudden changes in background sound are the main source of distraction. However, white noise does not guarantee better concentration. Personal preference, the task being performed, and the surrounding acoustic environment all matter.

Is white noise the same as sound masking?

No. Although the terms are sometimes used interchangeably, professional sound masking uses carefully controlled background sound designed for a specific acoustic purpose, such as reducing speech intelligibility over distance. Ordinary white noise is not necessarily calibrated to a room in the same way.

Does white noise reduce office noise?

Not physically. White noise does not remove existing sound. It adds background sound that may make certain other sounds less noticeable. Sound-absorbing materials are used when the aim is to control reflections and reverberation within the room.

What is the difference between white, pink and brown noise?

The main difference is how energy is distributed across frequencies. White noise tends to sound brighter and more hiss-like. Pink noise has relatively more low-frequency energy and often sounds softer. Brown noise places even greater emphasis on lower frequencies and has a deeper sound.

Can white noise fix poor room acoustics?

No. White noise can mask certain sounds, but it does not solve excessive reverberation, poor sound insulation, or unwanted sound reflections. These problems require different acoustic measures.

Which is better: sound masking or acoustic panels?

It depends on the problem. Acoustic panels help control reflections and reverberation. Sound masking can help make conversations less noticeable or intelligible over distance. In some workplaces, a combination of both approaches may provide the most suitable acoustic environment.
