EN ISO 16283-1:2014 PDF

Overview

EN ISO 16283-1:2014 (ISO 16283-1:2014) - "Acoustics - Field measurement of sound insulation in buildings and of building elements - Part 1: Airborne sound insulation" - specifies field procedures to determine airborne sound insulation between two rooms using sound pressure measurements. It applies to rooms with volumes from 10 m³ to 250 m³ and in the frequency range 50 Hz to 5 000 Hz. Results are frequency‑dependent and can be converted to a single-number rating per ISO 717-1.

Key topics and technical requirements

• Measurement scope: In situ determination of airborne sound insulation between adjacent rooms (unfurnished or furnished), including cases where the sound field may not be diffuse.
• Frequency and volume limits: Designed for 50 Hz–5 000 Hz and room volumes 10–250 m³.
• Instrumentation: Requirements for microphones, sound level meters, loudspeakers, calibration and verification of equipment before and during testing.
• Measurement procedures:
  • Default and low-frequency procedures for sound pressure level measurement.
  • Options for microphone handling: fixed positions, mechanized continuously‑moving microphone, or manually scanned microphone.
  • Guidance on generation of sound field in the source room.
• Background noise: Methods for assessing and correcting measurements for background noise.
• Reverberation time: Measurement of reverberation time in the receiving room (default and low-frequency methods) as part of the calculation.
• Data processing: Conversion to octave bands, energy-averaging, and conversion of frequency-dependent results into single-number ratings (ISO 717‑1).
• Quality and reporting: Recording requirements, uncertainty estimation and detailed test-report contents. Annexes provide requirements for loudspeakers and example measurement layouts.

Practical applications and users

Who uses EN ISO 16283-1:

• Acoustic consultants and field testing laboratories performing in-situ sound insulation tests.
• Building inspectors, architects and contractors verifying compliance with acoustic performance requirements.
• Manufacturers and façade/partition installers validating installed performance.
• Regulatory authorities and certification bodies assessing building conformity to acoustic standards.

Common uses:

• Verification of in-situ airborne sound insulation after construction or renovation.
• Troubleshooting airborne noise problems and comparing performance of partitions and junctions.
• Providing data for compliance with building regulations and for single-number ratings under ISO 717-1.
• Input to acoustic design decisions and product performance validation.

Related standards

• ISO 16283 series (other parts cover impact sound insulation and façade sound insulation).
• ISO 717‑1 for conversion of measured data to single-number ratings.
• Supersedes earlier field methods in ISO 140 series (e.g., ISO 140-4, -5, -7, -14).
