Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

Introduction

This document describes survey test methods which can be used for surveying the acoustic

characteristics of the airborne sound insulation, impact sound insulation and of the sound pressure

levels from service equipment. The methods may be used for screening tests of the acoustical properties

of buildings. The methods are not intended to be applied for measuring acoustical properties of building

elements.

The approach of the survey methods is to simplify the measurement of sound pressure levels in rooms

by using a hand-held sound level instrument and by manually sweeping the microphone in the room

space. The correction for reverberation time can be either estimated by usage of tabular values or be

based on measurements. The measurement of airborne and impact sound insulation is carried out in

octave bands. For measuring sound from domestic service equipment, A - or C -weighted sound pressure

levels are recorded.

Measurements are performed with specified operation conditions and operation cycles. The operating

conditions and operating cycles given in Annex B are only used if they are not opposed to national

requirements and regulations.

The measurement uncertainty of the results obtained using the survey method is a priori larger than

the uncertainty inherent in the corresponding test methods on engineering level.

NOTE Engineering methods for field measurements of airborne and impact sound insulation are dealt with

in ISO 16283-1 and ISO 16283-2. Engineering methods for field measurements of airborne sound insulation of

façade elements and façades are dealt with in ISO 16283-3. An engineering method for measurement of service

equipment sound is dealt with in ISO 16032.

Acoustics — Field measurements of airborne and impact
sound insulation and of service equipment sound —
Survey method
1 Scope
This document specifies field survey methods for measuring:
a) airborne sound insulation between rooms;
b) impact sound insulation of floors;
c) airborne sound insulation of façades; and
d) sound pressure levels in rooms caused by service equipment.

The methods described in this document are applicable for measurements in rooms of dwellings or in

rooms of comparable size with a maximum of 150 m .

For airborne sound insulation, impact sound insulation and façade sound insulation the method gives

values which are (octave band) frequency dependent. They can be converted into a single number

characterising the acoustical performances by application of ISO 717-1 and ISO 717-2. For heavy/soft

impact sound insulation, the results also are given in overall A-weighted maximum impact sound

pressure level. For service equipment sound the results are given directly in A - or C -weighted sound

pressure levels.
