Building Acoustics Equipment Guide: ISO 16283 Systems for Asia
Complete guide to selecting building acoustics measurement equipment for ISO 16283 field testing — airborne sound insulation, impact sound insulation, facade testing, and room acoustics. Used by acoustic consultants, M&E engineers, and test laboratories across ASEAN, GCC, and South Asia for Grade-A offices, residential towers, hotels, hospitals, and education facilities.
What ISO 16283 Requires
- ISO 16283-1: Airborne sound insulation between rooms — DnT,w weighted single-number rating
- ISO 16283-2: Impact sound insulation through floor/ceiling assemblies — Ln,w weighted index
- ISO 16283-3: Facade sound reduction — R'w index for external walls and glazing systems
- Frequency range: 100 Hz – 3150 Hz in 1/3 octave bands (16 bands)
- Minimum 5 source positions and 5 receiver microphone positions per building element
- Signal-to-noise ratio ≥ 6 dB required in each 1/3 octave band
- Reverberation time T20 measurement required in both source and receiving rooms
Step 1 — Primary Measurement Instrument
- Nor150 Dual-Channel Analyser — Recommended for the full ISO 16283 suite: two synchronized microphone channels measure source and receiver rooms simultaneously; built-in T20 and DnT,w calculation; ISO 3382 room acoustics; ISO 9614 sound intensity
- Nor145 Sound Level Meter — Single-channel Class 1 for basic ISO 16283-1 airborne insulation surveys and background noise assessment during construction monitoring
Step 2 — Omnidirectional Sound Source
- Nor277 Dodecahedral Speaker — ISO 16283-1 compliant 12-driver omnidirectional array; sufficient output for rooms up to 100 m³; built-in amplifier; compatible with Nor150 and Nor145 tone generator output
Step 3 — Standard Tapping Machine
- Nor279 Standard Tapping Machine — ISO 16283-2 compliant; 5 hammers striking at 10 impacts/second; produces standardized impact force for Ln,w impact sound insulation measurement
Step 4 — Post-Processing Software
- NorReview Building Acoustics Module — Imports field data from Nor150 or Nor145; calculates DnT,w, Ln,w, and R'w per ISO 16283; generates ISO-formatted compliance reports with uncertainty estimates
Building Types and Target Values in Asia
- Residential (Singapore SS 553): DnT,w ≥ 45 dB between dwellings; Ln,w ≤ 63 dB
- Hotels (typical ASEAN specification): DnT,w ≥ 50 dB guestroom partitions; Ln,w ≤ 55 dB
- Offices and healthcare: DnT,w varies by room category — open-plan STI, private office ≥ 45 dB
- UAE, Saudi Arabia: GSAS and local codes reference ISO 16283 or equivalent EN ISO 16283 values
