Acoustics - Statistical distribution of hearing thresholds related to age and gender

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.

Acoustics - Statistical distribution of hearing thresholds related to age and gender

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.

Acoustics - Statistical distribution of hearing thresholds as a function of age

Le présent document fournit des données statistiques descriptives concernant le seuil d'audition de populations d'âges divers. Il spécifie la valeur médiane attendue de seuil d'audition donné par rapport au seuil d'audition médian à l'âge de 18 ans et la distribution statistique attendue de part et d'autre de la valeur médiane, pour la gamme de fréquences audiométriques de 125 Hz à 8 000 Hz et pour des groupes de personnes otologiquement normales d'âge donné compris entre 18 et 70 ans inclus.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
