Designation:E157498(Reapproved 2014)Standard Test Method forMeasurement of Sound in Residential Spaces1This standard is issued under the fixed designation E1574;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This test method provides guidance to the methodologyused in the measurement of building interior sound levels.1.2 This test method describes procedures for measuringsound in enclosed residential spaces produced by built-inutilities and major appliances such as plumbing,heating,ventilating,air-conditioning systems,refrigerators,and dishwashers.The measured values may then be used to assesscompliance,design,or habitation suitability.1.3 This test method does not promulgate or recommendacoustical criteria.1.4 This test method is not intended for obtaining data toevaluate indoor environments for:1.4.1 Commercial activities such as studios,communicationcenters,hospitals,and auditoria,and1.4.2 Effects from exterior sources such as aircraft,railroadoperations,motor vehicles,mining operation,weapons fire,etc.1.5 This test method is not intended for evaluating soundtransmission loss,sound absorption coefficient,or any otheracoustical aspects of the space or structure.1.6 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.7 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2C634 Terminology Relating to Building and EnvironmentalAcousticsE177 Practice for Use of the Terms Precision and Bias inASTM Test Methods2.2 ANSI Standards:3S1.4 Specification for Sound Level MetersS1.11 Specification for Octave-Band and Fractional-OctaveAnalog and Digital FiltersS1.40 Specification for Acoustical Calibrators3.Terminology3.1 DefinitionsFor definitions of acoustical terms used inthis standard see Terminology C634.3.2 Descriptions of Terms Specific to This Standard:3.2.1 background noiseto include sound propagating tothe measurement space from sources which are not undercontrol of the proprietor or occupant of the measurement space.See Terminology C634.3.2.1.1 DiscussionExamples include external utilities,traffic,and activity in adjacent residences.3.2.2 highest transient sounda sound characterized by abrief excursion of pressure level which exceeds the ambient orsteady sound.3.2.2.1 DiscussionThe transient sound may be accompa-nied by steady sound;for example,flushing of toilets orfurnace start-up.The highest transient sound is the maximumexcursion of the sound product by the source of interest duringthe source on-off cycle.3.2.3 measurement spaceresidential spaces with a definedboundary,usually a room or hallway,in which acoustical dataare to be acquired.Although the space may have a definedboundary,it does not have to be an enclosing boundary.3.2.3.1 DiscussionFor example;an L-shaped living room/dining room would be considered two spacesliving room anddining room.3.2.4 source of interesta source which is part of theresidence and which propagates sound into the measurementspace.3.2.4.1 DiscussionTypical sources of interest are built-in1This test method is under the jurisdiction ofASTM Committee E33 on Buildingand Environmental Acoustics and is the direct responsibility of SubcommitteeE33.08 on Mechanical and Electrical System Noise.Current edition approved March 1,2014.Published March 2014.Originallyapproved in 1994.Last previous edition approved in 2006 as E1574 98(2006).DOI:10.1520/E1574-98R14.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3Available from American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036,http:/www.ansi.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 utilitiessuchasplumbing,heating,ventilating,air-conditioning systems,and major appliances.3.2.5 source soundthe sound pressure level at a pointproduced solely by the source of interest.3.2.6 steady sounda sound whose pressure level remainssubstantially constant during the period of observation whenmeasured with the slow setting on the sound level meter.3.2.6.1 DiscussionExamples are a forced air blower and awater pump.4.Summary of Test Method4.1 This test method is a procedure for quantifying thesound from sources identified as the cause or potential cause ofnoise complaints in residential spac
