The Real Noise Conditions in Office Environments

Even well-designed offices generate continuous background noise that can travel into meeting spaces.

Typical Noise Levels:

• Open office conversations: 60–70 dB
• Movement and foot traffic: 55–65 dB
• Phones and office activity: 60–70 dB

Executive briefing rooms, however, require:

• 40–50 dB for clear communication and focus

👉 This difference creates a situation where speech from outside areas remains audible and distracting.

How This Affects Meetings and Decision-Making

Noise in executive spaces doesn’t just cause distraction—it impacts outcomes.

Key challenges include:

• Reduced clarity during presentations, especially when discussing detailed information
• Interruptions during conversations, requiring repetition
• Difficulty maintaining focus, particularly in longer meetings
• Lower perceived professionalism, especially when hosting clients or stakeholders

In environments where decisions matter, even small disruptions can have significant consequences.

Why Standard Office Dividers Don’t Solve the Problem

Many offices attempt to manage noise using:

• Glass partitions
• Fixed walls
• Basic accordion room dividers

While these may separate spaces visually, they often fail to control sound effectively.

Common limitations include:

• Low acoustic accordion partition STC rating
• Lack of proper sealing
• Minimal reduction in speech transmission
• Sound leakage through gaps and openings

👉 As a result, briefing rooms remain acoustically connected to the surrounding office.

OSHA Compliance – Illinois Office Environments

OSHA Standard Reference:

• 85 dB(A) – Action Level
• 90 dB(A) – Permissible Exposure Limit

Office environments typically operate below these thresholds, but sustained exposure to 60–70 dB noise levels can still impact:

• Focus and cognitive performance
• Communication clarity
• Overall workplace comfort

The Solution: FoldaSil® ANC-AP40-2 Acoustic Accordion Partition System

The FoldaSil® ANC-AP40-2 Acoustic Accordion Partition System provides a practical way to improve acoustic performance in executive environments without limiting flexibility.

Rather than completely isolating spaces, it reduces how sound travels and how clearly it is heard across areas.

It functions as:

• A high-performance acoustic accordion door system
• A movable accordion partition for office layouts
• A sound control room divider accordion solution for professional spaces

How ANC-AP40-2 Improves Executive Briefing Rooms

With proper acoustic separation, meeting spaces become more controlled and effective.

Key Improvements:

• Reduced noise transfer from open office areas
• Improved speech clarity during discussions
• Better focus and engagement for participants
• Enhanced professional environment for meetings and presentations

Before vs After: Meeting Room Performance

Before Installation:

• Noise levels: 60–70 dB from surrounding office activity
• Conversations interrupted by background noise
• Reduced focus and efficiency

After Installing ANC-AP40-2:

• Reduced to approximately 45–55 dB in briefing rooms
• Less intelligible background noise
• Improved clarity and productivity

👉 The result is a more controlled and professional meeting environment.

Why Accordion Partition Systems Work for Offices

Corporate environments require solutions that balance:

• Flexibility
• Cost efficiency
• Acoustic performance

With accordion partition systems:

• Spaces can be opened for collaboration
• Closed for focused meetings
• Reconfigured quickly without construction

Compared to permanent walls, accordion doors provide a more adaptable solution for evolving office needs.
