Commercial Soundproofing by Property Type
Wall, floor, ceiling, and HVAC soundproofing for hotels, multi-family, healthcare, restaurants, and 10 more property types — engineered in Tampa, delivered nationwide. Pick your building type below to see the assemblies, code targets, and field results we use most.
Fourteen Building Types, Fourteen Soundproofing Playbooks
Every property type has its own code targets, source noise, and weak points. Pick the closest match for your project to see assemblies, products, and the state subpage where local code and regional notes live.
Four Soundproofing Disciplines, One In-House Team
Most projects pull from at least two of these. We engineer all four under one roof so a wall detail integrates with the floor system, the door schedule, and the HVAC plan instead of fighting them.
Wall Soundproofing
Engineered partition assemblies that hit STC targets in standard wall depths.
- Mass-loaded membrane systems
- Resilient channel and isolation clips
- Mineral wool and high-density batts
- Double-stud and staggered-stud detailing
Floor and Ceiling Soundproofing
Footfall and impact-noise control for stacked units, with IIC-compliant assemblies.
- Acoustic underlayment and isolation pads
- Resilient hangers and ceiling pads
- Concrete topping and gypcrete detailing
- Field IIC and AIIC test verification
Doors, Windows and Penetrations
The weak links most assemblies miss. Sealing detail is what carries the lab rating into the field.
- STC-rated door and frame assemblies
- Acoustic perimeter and threshold seals
- Dual-glazed acoustic window units
- Outlet, conduit, and pipe-penetration sealing
HVAC and Mechanical Noise
Equipment, duct-borne, and rooftop noise mitigation for occupied spaces below or beside them.
- Duct silencers and lined plenum design
- Equipment isolation pads and inertia bases
- Rooftop unit enclosures and barriers
- NC and RC verification in occupied rooms
Numbers That Pass a Field Test or a Building Official
Soundproofing is only worth specifying when the field result matches the spec. Every assembly we recommend has a target, a tested rating, and a path to verification at punch list.
Performance targets follow IBC, HUD, FGI, and ICC criteria. Ratings cite the ASTM standard, the assembly, and the test conditions so the data holds up in lender review, code review, or HOA disputes.
- STC 50IBC minimum for party walls (lab)
- STC 55+Premium hotel and condo demising
- NIC 45+Field-measured airborne (E336)
- IIC 50IBC minimum for floor-ceiling
- AIIC 45+Field impact insulation (E1007)
- STC 35–45Acoustic doors and windows
- NC 30–40Background noise in occupied rooms
- HUD 45 STCMulti-family financing compliance
A Soundproofing Team That Stands Behind the Field Rating
Most acoustic firms hand off a spec and walk away. We engineer assemblies, ship the materials, train the sub on site, and field-test the result so the rating in the spec book is the rating that gets installed.

Property-Type Specialists
Fourteen building types with their own engineering playbooks — multi-family demising walls, hotel guestroom assemblies, hospital patient floors, school music rooms, and the rest.
-
Field-Tested Assemblies
Recommendations are based on installs that passed a real ASTM E336 or E1007 test, not just laboratory STC certificates.
-
State and Metro Code Awareness
Each property type has state-level subpages with local IBC amendments, AHJ practices, and regional detailing — so a Texas spec reads like a Texas spec, not a Florida one.

Sister Discipline: Acoustic Consulting
When a project also needs reverberation control, exterior noise modeling, or stamped engineering, the consulting team is on the same floor.
Discovery, Engineering, Specification, Installation
Same four steps on every soundproofing project, scaled to fit. A 12-unit condo retrofit runs the loop in three weeks. A 300-room hotel runs it across the build calendar with site visits at framing, insulation, and rock.
Discovery
Drawings review or site walk. Identify the source, the path, the receiver, and the code target the assembly has to clear.
Engineering
STC, IIC, and NC modeling against the room program. Compare assemblies before any product is named or quoted.
Specification
Wall sections, floor build-ups, door schedules, and CSI-format spec language a GC can hand to a sub.
Installation
Site visits during framing, mass installation, and rock to catch the details that turn STC 55 lab ratings into STC 50 field ratings.
Recent Soundproofing Work, By the Numbers
A small sample of completed soundproofing projects across property types. The full library lives in case studies, organized by industry.
Wood-Frame Hotel Hits STC 55+ Across 60,000 SF
Membrane-based assembly on a wood-frame La Quinta beat the alternative spec on cost and field performance.
New Orleans Duplex Cleared STC Field Test
Pre-drywall ASTM E336 testing on a duplex demising wall verified the engineered assembly before close-out.
Restaurant Private-Dining Sound Curtain
Operable acoustic curtain partition isolated a private dining room from the main floor without permanent wall construction.
Hotel HVAC Noise Pulled Below NC 35
Targeted PTAC isolation, duct lining, and rooftop barrier work brought guestroom background noise within design intent.
Airport Traffic Control Room Soundproofing
Mass-loaded membrane and an STC-rated door assembly isolated a Tampa control room from adjacent training and break areas.
Sazerac House Museum Soundproofing Membrane
Mass-loaded membrane on a historic New Orleans museum quieted exhibit AV between adjacent gallery rooms.
Soundproofing Questions We Get Every Week
What’s the difference between soundproofing and acoustic treatment?
Soundproofing blocks sound from passing between rooms. Acoustic treatment controls reflections inside a room. Mass-loaded assemblies and isolation handle the first; absorptive panels and ceiling clouds handle the second. Most projects need both, but the techniques are not interchangeable.
Do you serve projects outside Florida?
Yes — Tampa is HQ but the project map is national. Many property types have dedicated state-level subpages with local code references and regional detailing, and Wall Blokker and our other materials ship direct to job sites in all 50 states.
How early should soundproofing be specified?
Schematic design, ideally. Wall thickness, floor build-up depth, and HVAC routing are flexible then. By the time framing is up, retrofitting an STC 55 wall costs three to five times what it would have cost to detail from the start.
What rating do I need for an apartment demising wall?
IBC requires STC 50 lab rating between dwelling units. HUD requires STC 45 field-measured. Many lenders and luxury developers spec STC 55+ to differentiate the asset and reduce noise complaints. Field rating typically lands 5–7 points below lab rating, so a STC 55 lab assembly tends to deliver around STC 48–50 in the field.
Do you install your own products?
We can. Most large multi-family and hotel projects use their own framing and drywall subs, and we provide install training and field oversight rather than bidding the labor. For smaller retrofits we have also self-performed, especially on condo conversions, audiologist suites, and studio buildouts.
Have a Wall, Floor, or Room That Needs Soundproofing?
Send us the program — building type, square footage, the noise source, the state, and the target rating — and we’ll tell you which assembly we’d specify and what the field rating tends to land at.
