How to Soundproof a Commercial Office: Step-by-Step Guide

Office noise can harm productivity and health. Here’s how to fix it:

• Identify Noise Sources: Common culprits include HVAC systems, office equipment, conversations, and external sounds.
• Measure Noise Levels: Use professional sound mapping or a DIY sound meter.
• Soundproof Key Areas:
  • Walls and Ceilings: Use acoustic panels, soundproof paint, or additional drywall.
  • Doors and Windows: Install solid-core doors, double-glazed windows, and seal gaps with acoustic caulk.
  • Floors: Add rubber underlayments, acoustic carpets, or floating floor systems.
• Choose Effective Materials: Combine sound-blocking (e.g., Mass Loaded Vinyl) and sound-absorbing materials (e.g., acoustic foam).
• Consider Professional Help: Acoustic specialists can tailor solutions to your space and needs.

Finding Office Noise Problems

Main Office Noise Sources

Office noise can come from a variety of sources, creating an unpleasant environment for employees. Pinpointing these sources is the first step to introducing effective soundproofing solutions.

Here are some common culprits in modern offices:

Open-plan offices, often designed with minimal partitions and reflective materials like glass, tend to amplify these sounds. Identifying the sources is key to moving forward with precise noise level measurements.

How to Check Sound Levels

Once you’ve identified the sources, the next step is to assess the noise levels in your office. There are two main ways to do this:

• Professional Sound Mapping
  This involves hiring experts to:
  • Measure sound levels in different areas.
  • Identify surfaces that reflect noise.
  • Provide detailed acoustic reports tailored to your space.
• DIY Sound Meters
  A sound meter (costing around £300) can help you measure noise levels yourself. However, it won’t provide the in-depth analysis that professionals offer.

As Zigaflow.com explains, "Sound mapping, also known as acoustic mapping, is the process of visualising and measuring sound distribution within a space." ^[2]

When assessing noise, focus on areas where employees find it hard to concentrate. Research shows that 3 in 10 employees frequently lose focus due to office noise ^[1], making it a problem worth addressing quickly.

Keep in mind that different parts of the office may need varying levels of soundproofing. Quiet zones and meeting rooms often require stricter noise control compared to communal or reception areas.

Office Soundproofing: Step by Step

Wall and Ceiling Solutions

Reducing noise through walls and ceilings requires careful planning. The key is to add mass and seal any air gaps. Use acoustic sealant (priced around £25 per tube) at wall-ceiling joints, around outlets, cable entries, light fixtures, and HVAC vents. Increasing the mass of walls and ceilings can make a huge difference. Here are some common options:

Once you’ve tackled walls and ceilings, move on to doors and windows, which are often the main culprits for sound leakage.

Door and Window Treatment

Doors and windows are typical problem areas in soundproofing because even tiny gaps can let in a lot of noise.

For doors:

• Replace hollow-core doors with solid-core models.
• Add high-quality door seals and sweeps.
• Install double-door systems in areas where soundproofing is critical.
• Use weatherstripping to seal any remaining gaps.

For windows:

• Install double-glazed units with at least a 25mm air gap ^[3].
• Seal the edges with acoustic caulk.
• Use neoprene gaskets to separate the glass from the frames.
• Add secondary glazing if needed.

After securing walls, ceilings, doors, and windows, the next step is to address noise coming from the floors.

Floor Noise Reduction

Floor noise, whether from footsteps or furniture movement, can be managed with a combination of approaches to tackle both impact and airborne sounds.

Here are some effective floor treatments:

For best results, seal floor perimeters with acoustic caulk. While carpets are great for reducing impact noise, they don’t do much for airborne sound. Combining these methods can help create a quieter workspace.

Selecting Soundproofing Materials

Best Materials for Offices

For effective office soundproofing, combine sound-blocking and sound-absorbing materials. Using a mix of Mass Loaded Vinyl (MLV), soundproof drywall, and acoustic sealant creates a strong barrier against noise.

Here’s a quick overview of key materials:

"Soundproofing is when you use material to block sound from entering or exiting a room, while sound absorption is when you use materials to absorb sound created inside a room in order to create a better-sounding environment." – Acoustical Solutions ^[4]

If you’re working with a limited budget, there are affordable options that can still deliver solid noise reduction.

Cost-Effective Options

Affordable soundproofing solutions can still provide excellent performance without breaking the bank. For example, SilentCore Acoustic Wall Panels offer different Noise Reduction Coefficient (NRC) ratings based on thickness:

Another option is TroyStudio Acoustic Foam Panels, which achieve an NRC rating of 0.8 ^[6], making them ideal for smaller spaces when placed strategically.

For budget-friendly soundproofing, try these steps:

• Seal gaps: Use acoustic caulk to close joints and seams.
• Add mass: Install acoustic panels to walls.
• Use specialised materials: Whispermat is a cost-effective choice for walls and ceilings ^[5].

Materials with high NRC and Sound Transmission Class (STC) ratings are generally more effective. For example, Green Glue compound can increase walls or ceilings by up to 9 STC points ^[7].

Rather than investing in a single expensive solution, combining multiple affordable options often produces better results. Start by addressing the noisiest areas, and expand your efforts as your budget allows.
