Sound Masking vs Soundproofing: What's the Difference and Which Do You Need?

Noise is one of the most common challenges in modern open-plan and hybrid offices. Conversations, phone calls, meetings, keyboard sounds, and general movement can make it difficult for employees to concentrate or have private discussions. As businesses look for better workplace acoustics, two terms often come up: sound masking and soundproofing.

Although both can help improve the office environment, they work in very different ways. Sound masking makes unwanted sounds less noticeable by adding a consistent background sound, while soundproofing focuses on reducing the amount of sound that travels between spaces.

The right choice depends on the specific workplace challenge. Some offices may benefit from sound masking across a large open area, while others may need an enclosed soundproof office phone booth for private calls, focused work, or confidential conversations.

What Is Sound Masking?

Sound masking is an acoustic approach that uses a controlled background sound to make conversations and other unwanted noises less noticeable. It does not physically stop sound from traveling through walls or open spaces.

Instead, the goal is to reduce how easily people can hear and understand surrounding conversations.

How Sound Masking Works

A sound masking system produces a consistent, unobtrusive background sound throughout a designated area. The added sound increases the overall ambient sound level, making sudden noises and nearby conversations less distinct.

For example, an employee sitting across an open office may still hear a conversation several desks away, but the words may become less intelligible.

This distinction is important. Sound masking does not block or absorb sound in the same way as physical acoustic barriers. It changes how noticeable certain sounds are within the environment.

Where Sound Masking Works Best

Sound masking can be useful in environments such as:

• Open-plan offices
• Shared workspaces
• Reception areas
• Common areas
• Large office environments where major construction is difficult

It can be particularly helpful when a business wants to improve speech privacy across a broad area instead of creating individual enclosed rooms.

What Is Soundproofing?

Soundproofing is designed to reduce the transmission of sound from one space to another. It uses physical construction and acoustic principles to limit the movement of sound through walls, doors, gaps, ceilings, floors, and other structures.

Unlike sound masking, soundproofing works by addressing the path that sound travels through.

How Soundproofing Works

Effective soundproofing can involve several elements, including solid walls, acoustic materials, properly sealed doors, compression seals, and structural isolation.

The objective is to reduce sound transmission between spaces. The effectiveness depends on the construction, materials, gaps, structure, and quality of installation.

It is also important to understand that soundproofing does not necessarily mean complete silence. Even a well-designed acoustic enclosure may allow some sound to enter or escape.

For workplace applications, the more realistic goal is usually meaningful noise reduction and improved privacy, rather than eliminating every sound.

Where Soundproofing Works Best

Soundproofing is especially useful for:

• Private offices
• Meeting rooms
• Phone and video calls
• Confidential discussions
• Spaces requiring greater separation from surrounding workplace noise

For businesses that need a dedicated space for calls or focused tasks, an enclosed acoustic workspace can provide a more targeted solution than background sound alone.

Sound Masking vs Soundproofing: Key Differences

While sound masking and soundproofing can support better workplace acoustics, the two solutions address different problems.

The best approach depends on whether the primary concern is general workplace distraction, speech privacy, or sound containment.

Which Is Better for Open-Plan Offices?

Sound masking can be a practical option when noise comes from many different directions and the goal is to make surrounding conversations less noticeable.

If you want to understand why this happens in the first place, this guide on how sound travels in an open office and why walls alone don’t fix it explains the role of reflections, distance, and open layouts. 

However, employees who regularly need quiet spaces for calls, meetings, or concentrated work may benefit more from an enclosed acoustic area.

In these situations, an office pod or dedicated phone booth can create physical separation without requiring a business to rebuild the entire office.

Can You Use Sound Masking and Soundproofing Together?

Yes. In fact, combining both approaches can be useful in larger workplaces.

Sound masking can help manage general background noise across an open-plan area, while enclosed soundproof spaces can provide additional privacy for specific activities.

For example, a company could use sound masking throughout an open workspace while providing private pods for employees who regularly handle calls, meetings, interviews, or confidential discussions.

When Do You Need a Soundproof Office Phone Booth?

A soundproof office phone booth can be useful when employees need a dedicated space that separates calls and focused work from the surrounding office.

Instead of expecting background sound to solve every privacy issue, an enclosed booth creates a defined workspace for activities that require greater concentration or privacy.

For Private Calls and Video Meetings

Phone and video calls can become difficult when employees are surrounded by conversations and movement.

A dedicated booth can:

• Reduce surrounding distractions
• Create a dedicated calling space
• Support clearer conversations
• Give employees greater separation from busy work areas

This can be particularly useful for frequent client calls, virtual meetings, interviews, and one-to-one conversations.

For Focused Individual Work

Not every task requires a private room, but some work benefits from fewer distractions.

An enclosed phone booth or individual pod can provide a quieter environment for tasks such as writing, reviewing documents, preparing presentations, or completing focused computer work.

This allows businesses to provide dedicated focus areas without assigning a permanent private office to every employee.

For Confidential Conversations

Sound masking can make conversations less intelligible, but it does not physically enclose the person speaking.

For sensitive conversations, physical separation can provide an additional layer of privacy. A properly designed soundproof office phone booth can create a more controlled environment for discussions that should not be easily overheard.

How Office Pods Help Manage Workplace Noise

Office pods are increasingly used to create dedicated spaces inside open-plan workplaces. Instead of converting an entire area into permanent rooms, pods can provide enclosed spaces where employees can work, call, or meet.

Depending on the design, pods can support individual work, private calls, video meetings, and small group discussions.

Another advantage is flexibility. Modular workplace solutions can reduce the need for extensive construction when a company wants to change its office layout.

When evaluating an office pod, businesses should consider more than acoustic performance. Ventilation, lighting, power access, workspace size, comfort, and ease of installation can all affect how practical the pod is for everyday use.

Should You Buy Modern Office Pods or Use Sound Masking?

The decision should start with the specific noise problem rather than the technology itself.

Choose Sound Masking If...

Sound masking may be appropriate when:

• General background noise is the main issue
• The workplace has a large open layout
• Speech privacy needs to improve across a wider area
• Major construction is not practical
• Employees need a more consistent acoustic environment

Consider Office Pods If...

It may make sense to buy modern office pods when:

• Employees need dedicated spaces for calls
• Individual conversations require additional privacy
• Focused work is frequently interrupted
• The workplace needs flexible enclosed areas
• A permanent room renovation is not desirable

Office pods can provide targeted privacy while preserving the flexibility of an open workplace.

Consider Both Solutions If...

Some workplaces have several acoustic challenges at once.

For example, an office may have widespread background conversations while certain employees regularly need private spaces for calls and confidential meetings.

In this situation, sound masking can address the wider environment while pods provide dedicated spaces for higher-privacy activities.

How to Choose the Right Noise Control Solution for Your Office

Before choosing a solution, consider the following questions:

• Identify the main sources of noise.
  Determine whether the biggest problems come from conversations, calls, equipment, movement, or general office activity.
• Decide what matters most.
  Is the priority reducing distractions, improving speech privacy, or containing sound?
• Consider the office layout.
  A large open floor may benefit from a broad acoustic strategy, while specific teams may need enclosed spaces.
• Evaluate installation requirements.
  Consider whether permanent construction is practical or whether a flexible solution would work better.
• Think about future changes.
  If the office layout may change, movable or modular solutions can offer greater flexibility.
• Consider employee needs.
  Different teams may require different levels of privacy depending on daily tasks.
• Look at the complete workspace solution.
  Acoustic performance, ventilation, lighting, power, comfort, and usability should all be considered together.
