Office Soundproofing Guide: How to Create a Soundproof Office

Office soundproofing is essential in today’s office environments where noise, distractions, and constant interruptions can undermine focus and performance. A truly soundproof office does not mean complete silence – it means controlling sound so that unwanted noise is reduced, speech intelligibility is improved, and people can work, listen, and communicate effectively.

‍

Whether you are dealing with open plan offices, busy meeting rooms, or a growing hybrid work environment, this guide walks through a practical, step by step plan to reduce noise, improve acoustics, and create a more productive space.

‍

Making your office "sound proof" may be easier than you think. At Persy Booths, we work closely with organisations tackling these challenges every day – particularly where phone calls, client calls, and privacy are critical. The noise reduction systems you need may be quite different to others, depending on your people and your office space. And remember that you don't need every product and every feature available – just the right solution to create the right soundproofing level for you. We hope the advice in this article helps you achieve that.

Key takeaways from this article

• Office soundproofing requires both blocking sound and improving sound absorption
• Small fixes like sealing gaps and improving door performance can dramatically reduce sound leakage
• Open plan offices need zoning, acoustic panels, and ceiling treatments rather than full isolation
• A structured noise audit helps identify the real sources of unwanted noise
• Office pods provide a fast, flexible way to create noise-free zones and maintain privacy without structural work

In modern office space design, aesthetics and flexibility often take priority – but acoustics are often overlooked. The result is background noise, ambient noise, and overlapping conversations that make it difficult to focus or hear clearly.

Workplace noise is not just a nuisance – it is a measurable productivity issue. Recent research from Forbes shows that noise acts as a stressor and reduces concentration, making it harder for employees to perform deep work and maintain focus.

‍

Effective office noise reduction delivers several important benefits:

• Better focus and productivity – people can concentrate without constant interruption
• Improved call quality – especially for client calls and remote collaboration
• Greater confidentiality – essential for HR, legal, and leadership conversations
• A calmer work environment – reducing stress caused by unwanted noise

Office soundproofing plays a critical role in maintaining privacy. In many offices, phone calls and meetings involve sensitive information – yet sound leakage through existing walls, door frames, or ceilings means conversations can be overheard.

By improving sound isolation and using acoustic solutions that absorb sound, organisations can ensure that voices remain contained within a room.

Open plan offices are designed for collaboration, but they often create a constant mix of voices, movement, and background noise.

Studies show that acoustic comfort directly affects employee wellbeing, concentration, and job satisfaction, reinforcing the need for effective office soundproofing. Using acoustic panels, ceiling baffles, ceiling clouds, and other soft materials helps dampen noise and reduce reverberation.

Before investing in solutions, it is important to understand the difference between blocking sound and absorbing it. It is worth taking a moment to appreciate the difference between soundproofing vs sound absorbing. Blocking sound prevents sound waves from travelling between spaces, while absorbing sound reduces echo within a room. A successful strategy uses both.

Airborne noise includes voices and phone calls, while impact noise comes from vibration such as footsteps or moving furniture. Understanding this difference helps determine the right approach.

• Sealing gaps
• Adding mass
• Decoupling
• Damping

‍

These principles underpin all noise reduction solutions.

Before purchasing acoustic products, identify where noise originates and how it travels.

Common issues include:

• Hollow core door construction
• Gaps in door frame and walls
• Ceiling voids
• Hard floors and reflective surfaces

Define measurable outcomes such as improved speech intelligibility or reduced background noise. It may be helpful to see what other businesses consider to be acceptable noise levels in the workplace.

• Install weather stripping
• Seal cracks
• Tighten door frame gaps

‍

These simple fixes can significantly reduce sound leakage.

Replacing a hollow core door with a solid one and improving seals can dramatically block noise.

• Add a second layer of drywall
• Use insulation
• Install acoustic panels

• Use ceiling baffles and ceiling clouds
• Add soft materials such as carpet

‍

These reduce echo and absorb sound across different frequencies.

Focus on door seals, wall construction, and echo control to maintain privacy.

Use zoning, acoustic panels, and furniture to reduce noise in open spaces.

Prevent noise spill and improve acoustic comfort.

A dedicated soundproof phone booth provides a quiet, enclosed space for phone calls, focused work, and moments where concentration really matters. These pods:

• Reduce ambient noise
• Improve voice clarity
• Provide personal space for focus

A flexible team meeting booth allows teams to collaborate privately without structural changes. These pods:

• Improve sound isolation
• Reduce sound leakage
• Provide scalable acoustic solutions

• Separate quiet and noisy areas
• Encourage awareness of noise

Headphones can help reduce background noise but do not solve overall acoustic issues. (And bear in mind that people using headphones may end up talking louder!)

Options include:

• Low-cost fixes
• Mid-range acoustic products
• High-performance structural upgrades

• Ignoring gaps
• Treating only one surface
• Overlooking ceilings and floors

Office soundproofing requires a layered approach combining sealing, absorption, and structural improvements. By starting small and scaling up, organisations can create a quieter, more productive work environment.
