UNE-EN ISO 16032:2024

This document specifies methods for measuring the sound pressure level from service equipment in

a building or from other sound sources inside or outside of the building. This document specifically

covers measurements of sanitary installations, mechanical ventilation, heating and cooling service

equipment, lifts, rubbish chutes, boilers, blowers, pumps and other auxiliary service equipment, and

motor driven car park doors; however, it can also be applied to measurements of equipment or activities

in in or nearby a building. To include noise from sport facilities, pubs etcetera inside or outside the

building. The measurement of noise from external sound sources generating ground-borne noise are

not included in this standard.

The methods are suitable for rooms with volumes of approximately 300 m3 or less e.g. in dwellings,

hotels, schools, offices and hospitals. The standard is generally not intended for measurements in

large auditoriums and concert halls, nor where the source is located at a distance from the building

where sound propagation may change with weather conditions. However, the operating conditions and

operating cycles in Annex B can be used in such cases.

The service equipment sound pressure level is determined as the maximum A-weighted and optionally

C-weighted sound pressure level occurring during a specified operation cycle of the service equipment

under test, or as the equivalent continuous sound pressure level in one third octave bands determined

with a specified integration time. A-weighted and C-weighted values are calculated from one third

octave band measurements or optionally from octave band measurements.
