Why Building Acoustics Matter
Sound insulation is a critical factor in building quality. Poor acoustics lead to noise complaints, reduced property values, and in commercial settings, decreased productivity. Building codes worldwide mandate minimum acoustic performance standards that must be verified through field measurements.
Airborne sound insulation (walls, floors, facades) and impact sound insulation (footfall noise) are the primary metrics. Measurements must account for room volumes, surface areas, and background noise to produce standardized single-number ratings like DnT,w and L'nT,w.
Reverberation time (RT60) is equally important for spaces where speech intelligibility or acoustic comfort matters - classrooms, offices, healthcare facilities, and performance venues all require careful acoustic design and verification.

Key Measurement Capabilities
Bedrock Elite instruments provide all the functionality needed for comprehensive building acoustics assessment.
Sound Insulation
Measure R', DnT, and L'nT with automatic calculation of single-number ratings (Rw, DnT,w, L'nT,w) and spectrum adaptation terms (C, Ctr).
Reverberation Time
RT60, EDT, T20, and T30 measurements in octave and 1/3 octave bands. Impulse response and interrupted noise methods supported.
Real-Time Analysis
1/1, 1/3, 1/6, and 1/12 octave band analysis for detailed spectral characterization and noise source identification.
Application Areas
Residential Buildings
Party wall testing, floor impact, and facade insulation for new construction and renovations.
Commercial Spaces
Office acoustic privacy, conference room isolation, and open-plan noise control.
Educational Facilities
Classroom acoustics, reverberation control, and inter-room isolation for learning environments.
Performance Venues
Concert halls, theaters, recording studios - optimizing room acoustics for their intended purpose.
Print an on-site measurement record
For on-site building acoustics checks, a compact printed ticket captures the measured level immediately — useful before preparing a full report. Bedrock Elite can support USB printer output depending on the instrument configuration; please confirm before purchase.
