ACOUSTIC AUDITS
& FIELD TESTING.
Comprehensive on site testing utilizing high precision sound level meters and analyzer systems to detect leakage, measure STC ratings, and verify compliance.
PRECISION ACOUSTIC MEASUREMENT & ANALYSIS
Acoustic performance cannot be assumed it must be measured. We conduct rigorous field audits using Class 1 sound level meters, real time frequency spectrum analyzers, and calibrated signal generators to evaluate existing environments or verify newly constructed spaces.
From identifying structural acoustic leaks and measuring speech privacy indices (STI/PI) to validating STC/IIC field ratings, our empirical diagnostic reports give you clear, actionable data and official compliance verification.
ENGINEERED CAPABILITIES
On-Site STC & FSTC Field Testing
Measurement of Sound Transmission Class across walls, partitions, and doors using calibrated pink noise generators and dual channel analyzers.
Reverberation Time (RT60) Profiling
Impulse response and decay measurements across fractional octave bands to evaluate room reflection characteristics.
Acoustic Leakage & Flanking Audits
Ultrasonic and acoustic signal mapping to identify sound bridges, unsealed penetrations, and structural weakness zones.
Speech Privacy (STI & PI) Testing
Assessment of Speech Transmission Index and Privacy Index for confidential executive suites, medical facilities, and legal offices.
Environmental & HVAC Noise Surveys
24-hour background noise logging (NC/NR curves) to assess HVAC rumble, ambient environmental noise, and municipal code compliance.
Impact Noise (IIC / FIIC) Testing
Standardized tapping machine testing to evaluate floor ceiling assemblies against footstep and impact noise transmission.
