We assess vibration levels in ventilation systems and ducting, install high-density fiberglass dampeners, measure decibel levels, and isolate noise in commercial buildings. No video streaming — only physical acoustic engineering.
Request a site assessmentMeasurable attenuation for ventilation, ductwork, and industrial equipment.
Modal analysis of vertical and horizontal duct runs. We identify standing wave patterns using precision microphones and FFT analyzers, then install tuned mass dampeners at anti-nodal points. Typical attenuation: 10–16 dB in the 63–250 Hz band.
Custom baffle placement for industrial exhaust fans and HVAC plenums. Inline, elbow-mounted, or plenum-chamber configurations. Achieves 8–12 dB reduction across 500–4000 Hz with minimal pressure drop. Materials rated for ducts up to 120°C.
Spring isolators, neoprene pads, and floating slab systems for air handling units. Field measurements show spring mounts with 25 mm deflection reduce floor vibration velocity by 90%. Includes wind uplift and seismic bracing compliance.
Broadband noise control for fans in manufacturing and processing plants. Hybrid dampener placement at fan outlet and first 90° elbow. Typical insertion loss of 8–12 dB without exceeding static pressure limits.
Room-by-room and duct-by-duct noise surveys using Class 1 sound level meters. We produce contour maps of sound pressure levels and identify dominant frequency bands. Reports include recommended treatment locations and expected attenuation.
Assessment of existing duct liners and sound attenuators. We measure insertion loss, pressure drop, and degradation over time. Recommendations include replacement schedules and material upgrades for high-temperature or corrosive environments.
One acoustic audit identifies the exact source of duct resonance and structural vibration. We provide a detailed attenuation plan with measurable decibel targets.

High-rise HVAC duct resonance solved with tuned mass dampeners.
Hospital AHU isolation using spring mounts with 25 mm deflection.
Industrial exhaust fan noise mitigated with hybrid fiberglass placement.
“The duct resonance analysis saved us from a costly redesign. The 14 dB reduction was exactly what our tenant required.”
“We tested three dampener configurations and their field data matched our simulation within 2 dB. Highly practical approach.”
Common inquiries about our acoustic assessment and insulation services.
We evaluate rectangular, spiral, and flexible ductwork in commercial HVAC, industrial exhaust, and ventilation shafts. Our diagnostics cover low-frequency standing waves and high-frequency broadband noise.
We use calibrated sound level meters and real-time analyzers to measure decibel levels before and after installation. Insertion loss is calculated across octave bands from 63 Hz to 8 kHz, with results documented in a detailed report.
Yes. We design retrofit solutions using spring isolators or neoprene pads that fit under existing AHU bases. Each installation accounts for static deflection, wind loads, and seismic requirements without disrupting ongoing building operations.
A standard diagnostic for a single duct run takes one to two days on-site, followed by three to five business days for data analysis and report generation. Complex multi-zone systems may require additional measurement cycles.
We perform modal analysis and finite element modeling for critical duct runs to predict resonance frequencies and optimize dampener placement. This reduces trial-and-error and ensures measurable attenuation from the first installation.
