Acoustical
Testing Services
E4 Acoustics travels to your facility to perform calibrated, on-site acoustical testing — then delivers a clear, professional report with findings and recommendations. We serve commercial, institutional and public-sector clients across the Midwest, including government & military, retail stores, restaurants & bars, arenas & casinos, music venues, colleges & universities, and manufacturing plants & industrial facilities. We also perform outdoor environmental noise testing for commercial and government clients. Please note: we do not perform residential neighbor-noise testing.
We measure ambient and background noise, HVAC and mechanical equipment noise, and occupational/industrial noise levels for plants, retail, restaurants, bars, arenas and casinos. We report against NC/RC room criteria and occupational exposure levels, and perform outdoor environmental noise testing for commercial and government clients (no residential neighbor-noise testing).
We measure reverberation time (RT60) by octave band per ISO 3382 to quantify echo and "live" room behavior in arenas, gymnasiums, houses of worship, restaurants and convention spaces. Testing pinpoints problem frequencies and predicts how much acoustical treatment a space needs for clear speech and music.
Field Sound Transmission Class (FSTC/ASTC) testing of walls, floor-ceiling assemblies and partitions per ASTM E336 and E413. We document how much sound transfers between spaces — bar to dining room, casino floor to meeting room, classroom to hallway — and what it will take to control it.
Performance
Sound Testing
Tune your room and your sound system
For venues, theaters, casinos, music clubs and houses of worship, performance sound testing measures how your space and your audio system actually perform together. We capture frequency response, sound pressure level (SPL), and speech intelligibility (STI/STIPA), then map coverage to find dead spots, harsh frequencies and uneven levels. You receive room-equalization data and clear recommendations so your system delivers consistent, professional sound everywhere in the room.

Class 1
Precision Instrumentation
State-of-the-art measurement — measured right, the first time
E4 Acoustics measures with a state-of-the-art Class 1 sound level meter and real-time analyzer — the highest accuracy grade defined by the international standard (IEC 61672-1). It is calibrated to NIST-traceable standards and field-verified before every engagement, so the numbers in your report stand up to scrutiny.
We invest in the most advanced instrument available so your results are beyond question. That precision is why our equipment is compliant for all government and military projects and every commercial application — from arenas, casinos and music venues to restaurants, retail, colleges and manufacturing plants. It captures noise, reverberation (RT60), sound transmission and full-spectrum frequency data in real time for defensible, repeatable results.
- Class 1 accuracy (IEC 61672-1)
- Calibrated to NIST-traceable standards
- Compliant for government, military & commercial projects
- Real-time octave / third-octave analysis
- Field-verified before every measurement
Our Testing
Process
1. Assess & Schedule
We discuss your facility and goals, then schedule on-site testing around your operations — including off-hours for arenas, casinos, restaurants and plants.
2. Measure On Site
Using calibrated instrumentation, we measure noise, reverberation, sound transmission and system performance to the relevant ISO and ASTM standards.
3. Report & Recommend
You receive a clear acoustical assessment with measured results, comparison to criteria, and practical recommendations — and we can install treatment if needed.
