Acoustics - Statistical distribution of hearing thresholds related to age and gender (ISO 7029:2017)
ISO 7029:2017 provides descriptive statistics of the hearing threshold deviation for populations of otologically normal persons of various ages under monaural earphone listening conditions. It specifies the following, for populations within the age limits from 18 years to 80 years for the range of audiometric frequencies from 125 Hz to 8 000 Hz:
a) the expected median value of hearing thresholds given relative to the median hearing threshold at the age of 18 years;
b) the expected statistical distribution above and below the median value.
For the frequencies from 3 000 Hz to 8 000 Hz, the median and statistical distribution for populations above 70 years are presented for information only.
ISO 7029:2017 also provides for information the expected median values at audiometric frequencies from 9 000 Hz to 12 500 Hz within the age limits from 22 years to 80 years.

Acoustique - Distribution statistique des seuils d'audition en fonction de l'âge et du sexe (ISO 7029:2017)
ISO 7029:2016 fournit des données statistiques descriptives concernant l'écart de seuil d'audition de groupes de sujets otologiquement normaux d'âges divers dans des conditions d'écoute monoaurale à l'aide d'écouteurs. Il spécifie les informations suivantes, pour des populations dont l'âge est compris entre 18 ans et 80 ans et pour la gamme de fréquences audiométriques de 125 Hz à 8 000 Hz:
a) la valeur médiane attendue de seuils d'audition donnés par rapport au seuil d'audition médian à l'âge de 18 ans;
b) la distribution statistique attendue de part et d'autre de la valeur médiane.
Pour les fréquences comprises entre 3 000 Hz et 8 000 Hz, la médiane et la distribution statistique pour des populations de plus de 70 ans sont présentées uniquement à titre d'information.
ISO 7029:2016 fournit également, à titre d'information, les valeurs médianes attendues aux fréquences audiométriques de 9 000 Hz à 12 500 Hz pour des personnes âgées de 22 ans à 80 ans.
Akustika - Statistična porazdelitev praga slišnosti v odvisnosti od starosti in spola (ISO 7029:2017)
Ta dokument podaja opisno statistiko odstopanja praga slišnosti pri različno starih osebah brez težav s sluhom pri monavralnem poslušanju prek slušalk. Za nabor avdiometričnih frekvenc od 125 Hz do 8000 Hz za osebe, stare od 18 do 80 let, določa naslednje:
a) pričakovana srednja vrednost pragov slišnosti glede na srednji prag slišnosti pri starosti 18 let;
b) pričakovana statistična porazdelitev nad in pod srednjo vrednostjo.
Za frekvence od 3000 Hz do 8000 Hz sta srednja vrednost in statistična porazdelitev za osebe, stare več kot 70 let, izključno informativni.
Ta dokument podaja tudi informacije o pričakovanih srednjih vrednostih pri avdiometričnih frekvencah od 9000 Hz do 12.500 Hz za osebe, stare od 22 do 80 let.
Podatki se uporabljajo za ocenjevanje stopnje izgube sluha, ki jo povzroči poseben povzročitelj v populaciji. Takšna primerjava je veljavna, če je preučevana populacija sestavljena iz oseb brez težav s sluhom, razen za vpliv posebnega povzročitelja. Primer posebnega povzročitelja je izpostavljenost hrupu in za to vrsto uporabe se v standardu ISO 1999 izbrani podatki iz tega dokumenta imenujejo »zbirka podatkov A«.
OPOMBA 1: Standard ISO 1999:2013, Zbirka podatkov A je osnovan na prejšnji izdaji standarda ISO 7029.
Podatki se lahko uporabljajo tudi za ocenjevanje posameznikovega sluha v povezavi s porazdelitvijo pragov slišnosti,
običajno za starostno skupino osebe. Vendar pri posamezniku ni mogoče natančno določiti, kateri del zaznane izgube sluha je posledica kopičenja
škodljivih vplivov na sluh, ki se povečujejo s starostjo, in kateri del je posledica drugih dejavnikov, npr. hrupa.
V tem dokumentu opredeljeno odstopanje praga slišnosti in ravni praga slišnosti, opredeljene v drugih mednarodnih standardih (ISO 389-1, ISO 389-2, ISO 389-5, ISO 389-8, ISO 8253-1, ISO 8253-2, IEC 60645-1), odražajo prag slišnosti posameznika ali ustreznega ušesa v odvisnosti od:
– pričakovane srednje vrednosti praga slišnosti pri 18-letnih osebah istega spola, ali
– referenčne ničelne ravni, določene v različnih delih standarda ISO 389.
V obsegu, v katerem referenčna ničelna raven označuje srednjo vrednost pri 18-letnih osebah,
bosta vrednosti dveh postavk enaki.
OPOMBA 2: Zaradi nekaterih razlogov ti vrednosti nista vedno enaki. Eden od razlogov je, da je bila referenčna ničelna raven določena na podlagi ravni praga slišnosti pri osebah, starejših od 18 let, vključno z osebami, starimi do 25 ali 30 let, ki imajo v povprečju nekoliko slabšo občutljivost sluha.
OPOMBA 3: ISO 28961 določa pričakovano statistično porazdelitev pragov slišnosti, izraženo v ravni zvočnega tlaka v decibelih, za osebe brez težav s sluhom, stare od 18 do 25 let, pri binavralnem poslušanju v prostem zvočnem polju. Omogoča izračun avdiometričnih frekvenc in tudi drugih frekvenc v intervalih po eno tretjino oktave v območju od 20 Hz do 16.000 Hz.

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
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

This third edition cancels and replaces the second edition (ISO 7029:2000), which has been technically
revised with the following changes:
— new data has been adopted, as explained in the introduction;
— estimation accuracy of expected medians and statistical distributions of hearing thresholds were
generally improved by modifying the formulae used;
— the age range for which the expected medians and statistical distributions of hearing thresholds are
calculable was extended to the age of 80 years at audiometric frequencies of 2 000 Hz and below; it
was up to 70 years for all frequencies in the previous editions.

ISO 7029:2017(E)
Introduction
The sensitivity of human hearing is well known to decrease with age and the impairment of hearing
develops more rapidly for sound at high frequencies than at low frequencies. Moreover, the magnitude
of this effect varies considerably among individuals.
When testing the hearing of persons markedly over 18 years of age, part of any observed hearing loss
will probably be associated with age. It is important to be aware of this when estimating the amount of
hearing loss attributable to other causes under investigation.
It should be noted that a decrease in hearing ability may not necessarily be caused by ageing itself, but
by many injurious influences during lifetime, which are not known in detail.
This document is based on a thorough examination of literature data on the differences between groups
having different ages for populations of otologically normal persons as defined herein. Distinction is
made between males and females since the difference is found to be of significance in the case of older
age groups. The data have been derived from investigations using pure tones transmitted to the ear
from an earphone, but no evidence is known that disqualifies their use for noise band stimuli.
This document is a revision of the second edition (ISO 7029:2000). The expected medians and statistical
distributions of hearing thresholds were re-estimated using audiometric data published after the
establishment of the first edition (ISO 7029:1984). All the data on which the second edition had been
based were discarded. Thus, this third edition describes the hearing sensitivity profile of people in
recent years.
Hearing thresholds presented in this document are generally lower at high frequencies than those in
the previous editions of this document. The 4 kHz dip observed in males has become negligibly small.
The source data of the previous editions might not have been screened rigorously in terms of hearing
abnormalities. Problems related to instrumentation might also have affected measurement data.
The expected median hearing thresholds at the frequencies from 9 000 Hz to 12 500 Hz are presented
for information. Audiometry at those frequencies is executable using an extended high-frequency
audiometer.
