Overview - ISO 10052:2021 (Acoustics, Survey method)
ISO 10052:2021 defines a practical survey method for in-situ acoustic measurements used to screen building and room acoustics quickly and consistently. It covers field measurements of:
- airborne sound insulation between rooms,
- impact sound insulation of floors (including heavy/soft impacts),
- airborne façade sound insulation, and
- sound pressure levels from service equipment in rooms.
The methods apply to dwellings or comparable rooms up to 150 m³ and produce octave‑band frequency dependent results that can be converted to single-number ratings using ISO 717-1 and ISO 717-2. Service equipment results are given directly in A- or C-weighted sound pressure levels; heavy/soft impact results include A-weighted maximum impact sound pressure level values.
Key technical topics and requirements
- Measurement scope and limits: Designed for rooms up to 150 m³ and intended as a survey - simpler and with larger uncertainty than full engineering test methods.
- Instrumentation: Use of sound level meters conforming to IEC/ISO performance standards (hand‑held measurement instruments are acceptable for the survey approach).
- Generation of sound field: Guidance on source placement and excitation for airborne and impact tests, including the standardized tapping machine for impact measurements.
- Frequency analysis: Results reported in octave bands (per IEC 61260 filters) and optionally converted to single-number indices (ISO 717 series).
- Reverberation and corrections: Use of reverberation index, reference reverberation time, or tabulated estimates to normalize results.
- Measurement procedures: Steps for measuring level differences, impact sound pressure levels, façade insertion loss and service equipment noise; includes required measurement ranges and precision considerations.
- Reporting: Template requirements and mandatory details for a test report; Annex B specifies operating conditions and cycles for reproducible service equipment measurements.
Practical applications
- Rapid acoustic screening surveys during design, refurbishment or prior to detailed testing.
- Pre‑acceptance checks and on-site verification of partition or floor performance when quick assessments are needed.
- Noise investigations related to building services (pumps, HVAC, lifts) using A/C-weighted sound pressure levels.
- Supporting decisions for retrofits, soundproofing, tenant complaints, and compliance checks where full engineering tests (ISO 16283 series) are not required or feasible.
Who should use ISO 10052:2021
- Acoustic consultants and building acousticians
- Building inspectors and enforcement authorities
- Architects, MEP engineers and contractors
- Facility managers and maintenance teams
- Manufacturers and installers of partitions, floor coverings and building services seeking rapid on-site assessment
