Diagnosing the Cause of Recurring Facility Noise
We measure your space with calibrated instrumentation first, fix the actual cause instead of the symptom, then hand you before-and-after data that proves the complaint is resolved.
Most Facility Noise Gets Diagnosed As A Panel Problem
A tenant files a noise complaint, and the reflex is to order acoustic panels. Panels are visible, they feel like action, and they get the complaint off your desk for a week. Then the complaint comes back, because the panels never touched the real cause.
Panels absorb reflected sound inside a room, so they help when the problem is reverberation. They do nothing for sound passing through a shared wall or floor, and nothing for a rooftop unit driving structure-borne noise. Buy panels for those problems and you have spent money on the wrong physics.
Without measurement, that choice is a coin flip. Roughly half the time the panels miss, the complaint returns, and the next purchase order goes out for more of the same. Two rounds of guessing usually cost more than measuring the space once.
Measurement changes the order of operations. Calibrated instrumentation shows how sound behaves in the actual space, separates reflection from transmission from mechanical noise, and points at the one mechanism creating the complaint. You treat that mechanism, not the guess.
For a facilities director, that turns noise from a recurring line item into a solved problem. The spend is targeted, the disruption is planned, and the result is measured. You walk into the leadership review with before-and-after data instead of another complaint log.

Common Challenges We Solve.
Recurring noise complaints from tenants and staff that never fully go away.
Conference rooms where speech carries straight through the wall next door.
Open offices where sound carries and conversations are hard to follow.
Rooftop and mechanical noise carried through the structure into occupied spaces.
Panels already installed that did not resolve the original problem.
Noise issues repeating across a portfolio on a fixed capital budget.
Complaints Recur When the Cause Goes Untreated

Adding Panels Without a Diagnosis Treats the Symptom
A noise complaint is a symptom. The reflection off a hard ceiling, the sound leaking through a demountable wall, and the hum from a mechanical room can all produce the same complaint, so the same panel purchase gets tried against all three.
When the fix targets the wrong mechanism, the complaint returns within weeks. The occupant loses confidence, leadership sees repeated spend with no result, and the noise becomes a standing item nobody can close. The building keeps its problem and the budget keeps paying for it.
Measurement comes first because you cannot see which mechanism is at work by walking the space. Calibrated instrumentation captures RT60, transmission between rooms, and mechanical signatures, and the numbers separate a reflection problem from a transmission problem from a mechanical one.
With the cause identified, the fix is specific and it holds. You spend once on the treatment the data supports, the complaint closes, and it stays closed. That is the difference between managing a noise problem and ending it.

Three Causes That Each Need a Different Treatment
When sound reflects off hard floors, ceilings, and glass, it layers inside the room and speech turns to noise. This is a geometry problem, measured as reverberation time, and it responds to absorptive treatment sized to the room, not to a generic panel count.
When sound travels through a wall, floor, or ceiling into the next space, absorption inside the room will not help. This is a transmission problem, measured as STC and IIC, and it responds to sealing paths and adding mass or isolation at the assembly.
When the source is a rooftop unit, pump, or fan, the noise rides the structure and shows up rooms away from the equipment. This is a mechanical problem, traced to its path, and it responds to vibration isolation and treatment at the source, not surface panels.
The three look identical from a complaint form and call for opposite solutions. That is why measurement precedes any recommendation. We identify which mechanism is driving your complaint, then specify the treatment that matches it, so the money goes where the physics is.

Spaces We Treat Across Your Portfolio
Complaints cluster in predictable places. Across a building portfolio, the same space types generate the same noise problems, and each has a measurable root cause. We measure the space first, then treat the geometry or transmission path actually driving the complaint.
- Private and open offices where speech carries between desks.
- Conference and board rooms with poor speech intelligibility.
- Labs and cleanrooms where equipment noise disrupts work.
- Lobbies and atriums where hard surfaces raise RT60.
- Fitness and wellness rooms with impact and music noise.
- Dining halls and cafeterias too loud for conversation.
- Education and training rooms where students miss speech.
- Multi-tenant common areas driving recurring tenant complaints.
- Worship and event spaces needing balanced reverberation.

Installed Inside Occupied Buildings, With Minimal Disruption
Your building stays open during the work. We plan installation around your operations, not the other way around. Occupants keep working, tenants keep their space, and your calendar drives the schedule. That planning starts during the assessment, long before the first panel goes up.
We phase the work zone by zone. One area gets treated while the rest of the floor runs normally, so no single department loses its space at once. On a portfolio, we sequence buildings the same way, matching your capital calendar and lease commitments.
When a space cannot go offline, we schedule installation after hours, overnight, or on weekends. Occupied floors, patient areas, and public lobbies get treated on your timeline, so staff arrive to finished work and the business day never stops.
Clean work protects your occupants and your finishes. Crews contain dust, protect floors and furniture, and clear the site each shift, so treated spaces reopen ready to use. You get one point of coordination from measurement through final walkthrough, not a string of vendors to manage.

Before-and-After Data to Report to Leadership and Tenants
Every project starts with a baseline. We measure the space with NIST-traceable Class 1 instrumentation and record what the room actually does: reverberation time, speech intelligibility, transmission between spaces, and where the complaint originates. That baseline becomes the number your fix has to beat.
After installation, we measure again under the same conditions. The before-and-after comparison shows the change in hard numbers: RT60 dropped, speech intelligibility improved, transmission loss increased. You see whether the space now meets its target, not whether it feels different on a walkthrough.
That comparison lands in a report you can put in front of leadership. Capital spend tied to a measured result answers the question every director gets asked: did it work? The data justifies the budget line and supports the next request across your portfolio.
Tenants and occupants get the same proof. A recurring complaint closed with data, not a promise, rebuilds confidence that facilities acts on what people report. When the next noise question comes up, you answer with a measurement instead of another guess at panels.

Engineered Systems We Supply and Install
We specify materials to the problem the measurement found, then supply and coordinate the install. The system matches the root cause, whether that is reverberation inside a room, sound moving between spaces, or equipment noise and vibration.
- Acoustic wall and ceiling panels to control reverberation.
- Sound masking and speech privacy systems for open spaces.
- Mechanical and HVAC noise control for equipment-driven complaints.
- Sound barriers and composite mass to block transmission.
- Floating floors and vibration isolation for impact and equipment.
- Acoustic enclosures for loud machinery and mechanical rooms.
- Room acoustic treatments engineered to a target RT60.
Featured Case Study
The Complaint That Kept Coming Back
A facilities team had already bought acoustic panels twice, and the occupant noise complaints kept coming back. Memtech measured the space with calibrated instrumentation and found the real cause was sound transmission between rooms, not reverberation. We corrected the transmission path and validated the fix with before-and-after data the director could show leadership.
Highlights:
- Two prior panel purchases had not resolved the recurring complaint
- Calibrated measurement showed transmission between rooms, not reverberation inside one
- Corrective work was phased around an occupied, operating building
- Before-and-after data gave the director proof to show leadership

Frequently Asked Questions (FAQs)
Why does a noise complaint come back after we already installed acoustic panels?
Panels absorb reflected sound inside a room. If the real cause is sound transmitting through a wall, floor, or shared duct, absorption changes little. We measure first to confirm whether you have a reverberation problem or a transmission problem, then treat the actual cause.
Why do you measure a space before recommending a fix?
Most facility noise problems get diagnosed as panel problems, but they are usually room-geometry or sound-transmission problems. Measuring with calibrated instrumentation tells us RT60, speech intelligibility, and where sound moves. Buying product without that data is a coin flip, and a wrong guess costs more than the measurement.
Can you work in our building while it stays occupied?
Yes. We assess and install inside occupied, operating buildings regularly. We phase the work by zone, schedule the loud steps after hours, and coordinate around your tenants and staff. You get a plan that names each phase and its impact before anyone starts.
What can I show leadership and tenants to prove the fix worked?
We capture calibrated measurements before and after the correction, so you hold data, not opinions. The report compares the two in plain language (RT60, speech intelligibility, transmission loss), documents the change, and gives you a result you can put in front of leadership and the people who complained.
What is the difference between sound masking and sound isolation?
Sound isolation blocks sound from moving between spaces through walls, floors, doors, and ductwork. Sound masking adds a low, engineered background level that covers speech so conversations stop carrying. Isolation fixes transmission. Masking raises speech privacy where isolation is impractical. We measure to tell you which your space actually needs.
How do you price a project, and what drives the cost?
Cost tracks scope: the assessment, the corrective materials, and installation coordination. We start with a measured diagnosis so you fund the fix that works instead of paying twice. Full-package work carries a performance guarantee. We can also phase the budget across periods rather than unbundle the engineered solution.
We have the same problem in several buildings. Can you handle a portfolio?
Yes. Recurring and portfolio-wide complaints are common, and they usually share a root cause worth diagnosing once. We measure representative spaces, build a standard for the problem type, and apply it across sites so you are not solving the same complaint one room at a time.
How long does a typical project take?
A single-space assessment usually runs a site visit plus a short turnaround on the report. Corrective work depends on materials and phasing inside an occupied building. Material lead times drive most of the schedule, and we give you a dated plan up front so nothing on your calendar slips.
What should I send you to get started?
Send a short description of the complaint, the space type, and when the problem shows up. Add a floor plan or a few photos if you have them, plus any product already installed. That is enough for us to scope a site visit and tell you what the measurement will cover.
Do you install the solution, or only assess it?
Both. We assess, design the correction, supply the specified materials, and coordinate installation through our trade partners. Installation is subcontracted and managed by us, so one team owns the diagnosis, the product, and the validated result. Full-package projects carry a performance guarantee.
