Acoustics -- Description, measurement and assessment of environmental noise -- Part 1: Basic quantities and assessment procedures

ISO 1996-1:2016 defines the basic quantities to be used for the description of noise in community environments and describes basic assessment procedures. It also specifies methods to assess environmental noise and gives guidance on predicting the potential annoyance response of a community to long-term exposure from various types of environmental noises. The sound sources can be separate or in various combinations. Application of the method to predict annoyance response is limited to areas where people reside and to related long-term land uses.
Community response to noise can vary differently among sound sources that are observed to have the same acoustic levels. This part of ISO 1996 describes adjustments for sounds that have different characteristics. The term "rating level" is used to describe physical sound predictions or measurements to which one or more adjustments have been added. On the basis of these rating levels, the long-term community response can be estimated.
The sounds are assessed either singly or in combination, allowing for consideration, when deemed necessary by responsible authorities, of the special characteristics of their impulsiveness, tonality, and low-frequency content, and for the different characteristics of road-traffic noise, other forms of transportation noise (such as aircraft noise), and industrial noise.
ISO 1996-1:2016 does not specify limits for environmental noise.
NOTE 1 In acoustics, several different physical measures describing sound can have their level expressed in decibels (e.g. sound pressure, maximum sound pressure, and equivalent continuous sound pressure). The levels corresponding to these physical measures normally will differ for the same sound. This often leads to confusion. Therefore, it is necessary to specify the underlying physical quantity (e.g. sound pressure level, maximum sound pressure level, and equivalent continuous sound pressure level).
NOTE 2 In this part of ISO 1996, quantities are expressed as levels in decibels. However, some countries validly express the underlying physical quantity, such as maximum sound pressure, in pascal or sound exposure in pascal-squared seconds.
NOTE 3 ISO 1996‑2 deals with the determination of sound pressure levels.

Akustika - Opis, merjenje in ocena hrupa v okolju - 1. del: Osnovne veličine in ocenjevalni postopki

Ta del standarda ISO 1996 opredeljuje osnovne veličine, ki se uporabljajo za opis hrupa v bivalnem okolju, in opisuje osnovne postopke ocenjevanja. Določa tudi metode za ocenjevanje okoljskega hrupa in podaja navodila za napovedovanje možnega odziva skupnosti na motnjo s hrupom pri dolgoročni izpostavljenosti različnim vrstam okoljskega hrupa. Zvočni viri lahko delujejo ločeno ali v različnih kombinacijah. Uporaba metode za napovedovanje odziva na motnjo s hrupom je omejena na območja, kjer bivajo ljudje, in z njimi povezano dolgoročno uporabo prostora.
Odziv skupnosti na hrup zvočnih virov, ki dosegajo enake zvočne ravni,
je lahko različen. Ta del standarda ISO 1996 opisuje popravke zvokov, ki imajo različne
značilnosti. Izraz »ocenjena raven« se uporablja za opis fizikalnih napovedi zvoka ali za meritve, ki jim je bil dodan vsaj eden popravek. Na podlagi ocenjenih ravni je mogoče oceniti dolgoročni odziv skupnosti.
Zvoki so ocenjeni posamezno ali v kombinaciji, kar po potrebi omogoča,
da pristojni organi upoštevajo posebne značilnosti impulznosti, tonalitete in
zastopanosti nizkih frekvenc ter različne značilnosti hrupa cestnega prometa,
drugih oblik prevoza (na primer letalski hrup) in industrijskega hrupa.
Ta del standarda ISO 1996 ne določa mejnih vrednosti za okolijski hrup.
OPOMBA 1: V akustiki je več različnih fizikalnih kazalnikov, ki opisujejo zvok, izražen v decibelih (npr. raven zvočnega tlaka, najvišja raven zvočnega tlaka in enakovredna neprekinjena raven zvočnega tlaka). Ravni, ki ustrezajo tem fizikalnim kazalnikom, se za isto vrsto zvoka običajno razlikujejo. To pogosto vodi do zmede.
Zato je treba opredeliti osnovne fizikalne veličine (npr. raven zvočnega tlaka, najvišjo raven zvočnega tlaka in enakovredno neprekinjeno raven zvočnega tlaka).
OPOMBA 2: V tem delu standarda ISO 1996 so veličine izražene kot ravni v decibelih. Vendar v nekaterih državah je uveljavljeno izražanje z osnovnimi fizikalnimi veličinami, kot sta najvišja raven zvočnega tlaka v paskalih ali zvočna izpostavljenost v paskalkvadrat sekundah.
OPOMBA 3: Standard ISO 1996-2 obravnava določanje ravni zvočnega tlaka.

Introduction
To be of practical use, any method of description, measurement, and assessment of environmental noise
is intended to be related in some way to what is known about human response to noise. Many adverse
consequences of environmental noise increase with increasing noise, but the precise dose-response
relationships involved continue to be the subject of scientific debate. In addition, it is important that
all methods used be practicable within the social, economic, and political climate in which they are
used. For these reasons, there is a very large range of different methods in use around the world for
different types of noise, and this creates considerable difficulties for international comparison and
understanding.
The broad aim of the ISO 1996 series is to contribute to the international harmonization of methods of
description, measurement, and assessment of environmental noise from all sources.
The methods and procedures described in this part of ISO 1996 are intended to be applicable to noise
from various sources, individually or in combination, which contribute to the total exposure at a site.
At the stage of technology at the time of publication of this part of ISO 1996, the evaluation of long-
term noise annoyance seems to be best met by adopting the adjusted A-weighted equivalent continuous

NACIONALNI UVOD
Standard SIST ISO 1996-1 (sl), Akustika – Opis, merjenje in ocena hrupa v okolju – 1. del: Osnovne
veličine in ocenjevalni postopki, 2016, ima status slovenskega standarda in je istoveten mednarodnemu
standardu ISO 1996-1 (en), Acoustics – Description, measurement and assessment of environmental
noise – Part 1: Basic quantities and assessment procedures, 2016.
Ta standard nadomešča SIST ISO 1996-1:2006.
NACIONALNI PREDGOVOR
Mednarodni standard ISO 1996-1:2016 je pripravil tehnični odbor Mednarodne organizacije za
standardizacijo ISO/TC 43 Akustika. Slovenski standard SIST ISO 1996-1:2016 je prevod
mednarodnega standarda ISO 1996-1:2016. V primeru spora glede besedila slovenskega prevoda v
tem standardu je odločilen izvirni mednarodni standard. Slovensko izdajo standarda je pripravil tehnični
odbor SIST/TC AKU Akustika.
V slovenski zakonodaji so nekateri kazalniki uporabljeni v poslovenjeni obliki in tako so upoštevani tudi
v besedilu tega slovenskega standarda, čeprav se v enačbah lahko pojavijo v angleški obliki. Tako velja:
t t , t = t , t = t , L L , L = L , L = T , L = L .
day = dan evening večer night noč day = dan evening večer night noč den dvn
Odločitev za izdajo tega standarda je 22. aprila 2016 sprejel SIST/TC AKU Akustika.
ZVEZA S STANDARDI
S privzemom tega mednarodnega standarda veljajo za omejeni namen referenčnih standardov vsi
standardi, navedeni v izvirniku, razen tistih, ki so že sprejeti v nacionalno standardizacijo:
SIST EN 61672-1 Elektroakustika – Merilniki ravni zvoka – 1. del: Specifikacije

Uvod
Za praktično uporabnost tega standarda naj bi se vse metode opisa, merjenja in ocenjevanja hrupa v
okolju na določen način povezale z odzivom človeka na hrup. Povečanje hrupa prinaša številne škodljive
posledice za okolje, vendar pa natančna povezava med dozo in učinkom še vedno ostaja predmet
znanstvenih razprav. Poleg tega je pomembno, da so vse uporabljene metode praktično izvedljive v
družbenem, gospodarskem in političnem okolju, v katerem so uporabljene. Posledično je po svetu na
voljo širok nabor različnih metod, ki se uporabljajo za različne vrste hrupa, kar predstavlja veliko težavo
pri mednarodni primerjavi in razumevanju.

Splošni cilj skupine standardov ISO 1996 je prispevati k mednarodnemu usklajevanju metod za opis,
merjenje in ocenjevanje hrupa v okolju iz vseh vrst virov.

Metode in postopki, opisani v tem delu ISO 1996, so namenjeni uporabi pri hrupu, ki izvira iz različnih
virov, bodisi posameznih bodisi v kombinaciji, in prispevajo k skupni izpostavljenosti na mestu merjenja.
Glede na tehnološke razmere ob času objave tega dela ISO 1996 se zdi, da je za ovrednotenje
dolgotrajne vznemirjenosti, ki jo povzroča hrup, najprimernejša uporaba popravljene A-vrednotene
ekvivalentne neprekinjene ravni zvočnega tlaka, znane kot "ocenjena raven".

Cilj skupine standardov ISO 1996 je oblastem zagotoviti podlago za opis in ocenjevanje hrupa v
bivalnem okolju. Na podlagi načel, opisanih v tem delu ISO 1996, je mogoče pripraviti ustrezne
nacionalne standarde, pravilnike in določiti sprejemljive mej
