Workplace acoustics improve when a design matches the room’s activities with the right combination of speech privacy, background sound, absorption and noise isolation. The most effective approach is not to add one product everywhere: separate incompatible activities, manage reverberation and sound paths, control equipment noise, and verify the finished space. These eight practical tips explain where to start, what each measure can—and cannot—do, and when project-specific acoustic advice is needed.

What should workplace acoustic design solve?
Begin by identifying the actual problem. A room that feels loud because speech reverberates needs a different response from a meeting room where voices carry through a door, or an open office where nearby calls distract people. The U.S. General Services Administration (GSA) describes four connected concepts that govern office acoustics: speech privacy, background sound, sound absorption and noise isolation. A successful plan considers all four rather than expecting a single finish or partition to do everything.

Absorption reduces reflected sound within a space, helping control reverberation and, in open areas, limiting how far sound travels. Isolation limits sound transmission between spaces or from outside; it depends on the construction and continuity of walls, doors, floors, windows and other parts of the sound path. Background sound is the existing or deliberately provided sound level in a space. Speech privacy depends on how clearly speech can be heard elsewhere, which is influenced by background sound, absorption and isolation together.
These distinctions matter when choosing finishes. Paint color and an ordinary painted finish do not, by themselves, provide meaningful sound isolation or replace purpose-designed absorption. Acoustic wall panels or ceiling products may help with reverberation when appropriately selected and installed, but they do not automatically make a room soundproof. GSA recommends sound-absorbing finishes to control reverberation in enclosed rooms and help decrease the distance sound travels through open spaces. That is a different task from stopping sound moving through a wall or door.
How can you improve workplace acoustics? Eight practical design tips
1. Zone the plan by activity and speech needs
Place quiet concentration work away from areas with frequent calls, group discussion or informal collaboration where the floor plan allows. The goal is not to make every office silent; it is to avoid placing activities with incompatible sound needs side by side without a reason. A call-intensive team may work better near shared meeting rooms, while focused work benefits from a quieter zone.

Pick the symptom - the matching free tool is one click away.
Start with a simple activity map: mark where people need sustained concentration, where they routinely speak to colleagues or callers, and where confidential conversations occur. Use that map to guide adjacencies before selecting finishes. ISO 22955:2021 provides guidance for open offices with different activity types, underscoring that layout and intended work are part of acoustic quality. Its recommendations are a planning resource, not a universal floor-plan formula.
2. Keep collaborating teams together—and separate other groups thoughtfully
People who regularly exchange information can often be grouped so that necessary conversation is less likely to disturb unrelated teams. ISO’s plain-language discussion of open-plan offices describes keeping people who need to share information within their distraction distance while placing other groups farther away. Treat that as a planning principle, not a standard distance that applies to every office: the relevant separation depends on the work, the layout and the sound environment.

Consider sightlines and circulation as well as distance. A corridor or shared service area can sometimes help separate work zones, while locating a noisy collaboration area beside a quiet focus zone may undermine the intended separation. If physical space is limited, reinforce zoning with suitable partitions, enclosed rooms and deliberate placement of call areas rather than assuming a sign or a change in paint color will control sound.
3. Use the ceiling as a major absorptive surface
Ceilings cover a large area and can be an important part of an open-plan acoustic design. GSA calls for highly absorptive ceilings as one component of an engineered open office. An absorptive ceiling can help manage reflections and reduce how far speech carries across an open space, but it does not provide the isolation of a full-height, well-sealed enclosure.
Choose the ceiling treatment and coverage for the room’s intended use and the project’s acoustic criteria. GSA’s P100 2024 includes specific criteria for certain federal facilities; for example, its Tier 1 open-plan office criteria specify an NRC/SAA of 0.90 across 100% of the ceiling. Those figures apply to the stated GSA space and performance tier, not every workplace. Coordinate acoustic choices with other project needs, including building systems, fire performance and maintenance requirements.
4. Select screens and partitions for the job they need to do
Partitions and screens can contribute to absorption and block some direct sound paths. GSA describes suitably designed panels of appropriate height as part of open-plan acoustic design. But a desk screen is not a private room: it cannot be assumed to stop speech travelling over, around or through it, and it does not create room-to-room isolation.
Specify screens according to their documented acoustic performance, height, placement and relationship to the surrounding surfaces. A product that absorbs sound may reduce reflections near a workstation; a barrier may interrupt a direct path between speakers and listeners. Those are related but distinct effects. Avoid claims such as “soundproof” unless the complete construction has been designed and assessed for the required isolation.

5. Provide enclosed rooms for confidential talk and focused meetings
Open work areas are not a substitute for acoustically private rooms. Make enclosed rooms available for confidential conversations, focused meetings and calls that would otherwise be disruptive. GSA recommends access to acoustically private meeting spaces and advises that speech-security needs be designed with a qualified acoustical consultant.
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Fix the driver behind crashes, sound loss and screen glitches3Repair Windows errors before they cause bigger problemsPrivacy depends on the entire enclosure, not just wall treatment. A consultant can help identify project-specific requirements and assess the sound path, including partitions, doors, floors, ceilings and adjoining spaces. A soft or absorptive finish inside a room can improve its sound quality, but it does not fix a weak boundary that lets speech leak into a neighboring workspace.
6. Reduce noise and vibration from building systems and equipment
Mechanical systems and office equipment can add a steady or intermittent noise layer that competes with conversation and concentration. GSA calls for limiting system and equipment noise and vibration, and its facilities standards address mechanical noise and vibration isolation. Include these sources in the design review rather than treating every complaint as a problem with wall or ceiling finishes.
Ask the design team to consider where equipment is located, how vibration may be transmitted into the building, and whether system noise is appropriate for the room’s use. If a space remains noisy after occupancy, identify whether the dominant source is mechanical, equipment-related, reverberant speech or sound passing between rooms before choosing a remedy. The fix for one source may do little for another.
7. Design the complete sound path between spaces
When the problem is sound traveling from one room to another—or entering from outside—review the whole boundary: partitions, doors, floors, ceilings, windows and their connections. Noise isolation is a property of the assembled sound path, not simply the surface treatment visible on one wall. A gap or weak element can undermine an otherwise substantial partition.

Absorptive wall panels may help reduce reverberation within a room when selected for that purpose. They do not replace construction designed to limit transmission. Similarly, ordinary paint is primarily a decorative finish; repainting a wall should not be presented as a soundproofing measure. For a painting or renovation scope, coordinate any acoustic panels or other treatments with the intended finish, documented product performance, installation details and applicable fire requirements.
8. Measure and commission the completed space
Acoustic design should be checked after construction, not assumed successful because specified products were installed. GSA says post-construction commissioning confirms whether acoustic standards were met. Agree on the intended performance and how it will be verified before the work is complete, so any shortfall can be traced to the relevant room, boundary, system or finish.
ISO 3382-3:2022 specifies a method for measuring acoustic parameters in unoccupied open-plan offices, including quantities related to how speech decays with distance from a speaker. It is a measurement standard, not a promise that a particular office will meet a target. Project-specific targets and any speech-security assessment should be set with qualified professionals. Measurements made in an unoccupied office also have a defined scope; they should not be casually treated as a complete picture of every condition during a busy workday.

| GSA P100 2024, Tier 1 open-plan offices | NRC/SAA 0.90 across 100% of the ceiling; 0.8 across 25% of walls; RT60 of 0.8 seconds | Criteria for the specified GSA office type and performance tier—not a blanket target for every workplace. |
| GSA P100 2024, Tier 1 meeting rooms with frequent tele/video conferencing | NRC/SAA 0.90 across 100% of the ceiling; 0.8 across 25% of walls; RT60 of 0.5 seconds | Criteria for the specified meeting-room use and tier. Room function matters. |
| WELL v7, sound masking when used | 45–48 dBA in open workspaces; 40–42 dBA in enclosed offices, measured from the nearest workspace | Levels specified by this WELL feature. They are not universal masking targets or a substitute for project design. |
GSA’s P100 is a federal facilities standard, so its values should not be presented as a general building-code requirement for every organization. The WELL v7 levels are likewise tied to its sound-masking feature. Sound masking is a designed and measured condition, not simply a speaker playing background noise. If considered, it should be coordinated with the space’s purpose and acoustic design, then set and verified appropriately.

How should a team choose between acoustic treatments?
Match the intervention to the sound problem before comparing products. Ask five questions: Is the concern reverberation, sound traveling across an open area, transmission between rooms, outside noise, equipment noise or speech privacy? What activities take place in the affected zone? Does the proposed treatment absorb sound, interrupt a direct path, isolate a room or provide background masking? Is its performance documented for the intended application? What installation, fire-performance and commissioning considerations apply?
For example, adding an absorptive ceiling may address reflections in an open area, while a confidential meeting room may need a carefully designed enclosure and door. A screen can help with a nearby direct sound path but is not equivalent to either solution. A wall panel can be relevant when reverberation is the problem, but it is not a stand-in for a properly designed wall assembly. If the source is mechanical noise, changing decorative finishes alone is unlikely to address the cause.
Plan the acoustic strategy alongside the interior finish schedule. Painting can provide the desired color and appearance, while dedicated acoustic products and building assemblies address sound-related functions. Keep those roles clear in specifications and communications, and confirm that any product’s stated performance matches the intended use rather than relying on a broad marketing label.

Which standards and guidance are useful?
GSA P100: Facilities Standards for the Public Buildings Service (2024) lays out acoustic concepts and criteria within the scope of federal facilities. ISO 22955:2021 addresses acoustic quality in open office spaces, including differences in activity. For measurement, the current cited method is ISO 3382-3:2022, which covers acoustic parameters in open-plan offices. The WELL v7 sound-masking feature sets context-specific levels for spaces using masking. ISO’s plain-language explanation of open-plan distractions is useful for understanding layout and distraction-distance concepts; its discussion refers to an earlier measurement-standard edition, so use ISO 3382-3:2022 for the current measurement reference.
Frequently Asked Questions
Can ordinary wall paint make an office quieter?
Ordinary paint is a decorative finish, not a substitute for acoustic absorption or sound-isolating construction. If noise is the concern, identify whether the issue is reverberation, transmission or equipment sound before specifying a treatment.
What does RT60 mean in an acoustic specification?
RT60 is a measure of how long sound takes to decay by 60 decibels in a room. It describes reverberation behavior; by itself, it does not tell you how well a wall or door blocks sound between rooms.
Are GSA’s office acoustic values mandatory for every workplace?
No. The cited values are criteria in GSA’s P100 for specified federal-facility room types and performance tiers. Other projects should use requirements applicable to their own jurisdiction, building type and design brief.
What is the difference between NRC and SAA?
NRC and SAA are sound-absorption ratings used to describe how a material absorbs sound; neither is a measure of how much sound a wall assembly isolates between rooms. Compare ratings only in the context of the specified product and the project’s intended application.
