Full title and description

Acoustics — Measurement of sound pressure level from service equipment or activities in buildings — Engineering method. Specifies an engineering method for measuring sound pressure levels produced by building service equipment and activities (e.g., sanitary installations, mechanical ventilation, heating and cooling equipment, lifts, rubbish chutes, blowers, pumps, motor‑driven car park doors) in rooms such as dwellings, hotels, schools, offices and hospitals.

Abstract

This standard defines procedures for measuring A‑weighted (optionally C‑weighted) sound pressure levels from service equipment or activities in rooms of approximately 300 m³ or less, using octave‑band measurements and engineering measurement methods appropriate for building acoustics assessments. It excludes measurements of external sound sources generating airborne or ground‑borne noise in the building and is not intended for large auditoria or concert halls.

Scope

ISO 16032:2024 specifies an engineering method for in‑room measurement of sound pressure levels from building service equipment and activities installed or carried out inside buildings. It covers sanitary installations, mechanical ventilation, heating and cooling service equipment, lifts, rubbish chutes, heating devices, blowers, pumps and other auxiliary service equipment, and motor‑driven car park doors; it can also be applied to other in‑building activities (for example, restaurants or sports facilities). It does not cover noise originating outside the building (air‑borne or ground‑borne external sources) and is not intended for large auditoria or concert halls. The procedures are intended primarily for rooms of around 300 m³ or less.

Key topics and requirements

• Engineering measurement method for in‑room sound pressure level assessment.
• Specification of measurement quantities: maximum A‑weighted level and optionally C‑weighted level, and equivalent continuous sound pressure level (Leq) with stated integration times.
• Use of octave‑band measurements to derive A‑ and C‑weighted values.
• Guidance on measurement positions, operating conditions and representative operating cycles for equipment under test.
• Instrumentation, calibration and uncertainty considerations for reproducible results.
• Reporting requirements and presentation of measured levels for building‑services noise evaluation.
• Applicability limits (room volumes ≈300 m³ or less) and exclusions (external airborne/structure‑borne noise, large auditoria).

Typical use and users

Used by acoustical consultants, building services engineers, testing laboratories, product manufacturers, architects and building regulators to assess and document noise from service equipment and in‑building activities for design verification, compliance checks, product evaluation and problem diagnosis in typical occupied spaces.

Related standards

Relevant complementary standards in building and environmental acoustics commonly used alongside ISO 16032 include standards for sound insulation, room acoustics, and noise emission measurement methods (for example standards addressing laboratory/field methods for noise emission, room acoustic measurement and airborne/impact sound insulation). Users should consult the applicable national/adopted versions (for example EN or national adoptions) and other ISO acoustics publications for full test suites.

FAQ

Q: What is this standard?

A: ISO 16032:2024 is an international standard that defines an engineering method for measuring sound pressure levels produced by service equipment or activities inside buildings.

Q: What does it cover?

A: It covers in‑room measurement procedures (including octave‑band measurements and the derivation of A‑ and C‑weighted levels) for equipment such as ventilation, heating/cooling systems, lifts, pumps, blowers, sanitary installations and motor‑driven car park doors, primarily in rooms of about 300 m³ or less. It excludes external source measurements and large auditoria.

Q: Who typically uses it?

A: Acoustical consultants, building services and HVAC engineers, test laboratories, manufacturers of building equipment, architects and regulators for design validation, compliance testing and noise mitigation planning.

Q: Is it current or superseded?

A: Current. ISO 16032:2024 (Edition 2, published February 2024) replaces and supersedes ISO 16032:2004.

Q: Is it part of a series?

A: It is part of the body of ISO standards on acoustics (work of ISO/TC 43/SC 2) and is intended to be used alongside other ISO and regional/national standards dealing with building acoustics, sound insulation and noise emission measurement methods.
