Building Acoustics Buying Guide: Complete ISO 16283 Equipment Selection
This guide helps acoustic consultants, M&E engineers, and test laboratories select the right combination of analyser, sound source, tapping machine, and software for ISO 16283 building acoustics field testing across Asia and the Middle East. Use this guide to build a complete system that meets regulatory requirements from Singapore to Saudi Arabia.
Who Needs a Building Acoustics Measurement System?
- Acoustic consulting firms performing pre-handover building acoustic certification
- ISO 17025 accredited test laboratories — need Class 1 instruments with calibration certificates
- M&E engineers on Grade-A office, hotel, residential tower, hospital, and education projects
- Government building authority inspection teams
- Universities with building science and acoustic engineering programs
Step 1 — Primary Measurement Analyser
- Nor150 Dual-Channel Analyser — Recommended — Two fully synchronized IEC 61672-1 Class 1 input channels; measures source and receiving room simultaneously; built-in T20, T30 reverberation; computes DnT,w, Ln,w, R'w; ISO 3382 room acoustics; ISO 9614 sound intensity; ISO 8041 vibration — the all-in-one professional system
- Nor145 Sound Level Meter — Entry Level — Single-channel IEC 61672-1 Class 1; suitable for basic ISO 16283-1 airborne surveys, background noise assessment, and construction noise monitoring; more cost-effective for high-volume residential testing
- Both instruments: PTB and LNE type-approved, 3-year manufacturer warranty, NorCloud connectivity
Step 2 — Omnidirectional Sound Source for Airborne Testing
- Nor277 Dodecahedral Speaker — ISO 16283-1 compliant 12-driver omnidirectional source; sufficient sound power output for rooms up to 100 m³; flat directivity index across test frequencies; compatible with Nor150 and Nor145 signal output
- Tip: use two source positions minimum per room — ISO 16283-1 requires sufficient SPL in the receiving room (SNR ≥ 6 dB at every 1/3 octave band)
Step 3 — Standard Tapping Machine for Impact Testing
- Nor279 Standard Tapping Machine — ISO 16283-2 compliant: 5 hammers, 500 g each, 10 impacts/second; designed to produce standardized impact force for Ln,w measurement on concrete and floating floor assemblies
- Place tapping machine in minimum 4 positions on the floor under test — record simultaneously with Nor150 receiver microphone
Step 4 — Post-Processing Software
- NorReview Building Acoustics Module — Imports .nox measurement files from Nor150 or Nor145; computes DnT,w, Ln,w, R'w using ISO 16283 formulas; applies Annex A reverberation correction; generates ISO-formatted compliance reports ready for authority submission
ISO 16283 Key Measurement Parameters
- DnT,w: Airborne insulation
- Ln,w: Impact insulation
- R'w: Facade reduction
- Range: 100–3150 Hz (1/3 oct)
- Min 5 source positions
- Min 5 receiver positions
- SNR ≥ 6 dB per band
- T20 all bands required
Regional Building Acoustic Standards Supported
- Singapore SS 553:2009 — residential and commercial acoustic requirements
- Malaysia MS standard acoustic requirements for buildings
- UAE GSAS — green building acoustic performance
- Saudi Arabia SASO — construction acoustic compliance
- ISO 16283 directly — for projects without a specific national standard
