Code List 143 - 15: Sound hazard

Explanation

Code 15 indicates that the publication contains sounds which may trigger seizures.

Sounds hazards are currently not well defined, so there is no standard way to check if the sounds in a publication may affect readers.

When publishers make sound hazard claims, they should provide details about the hazard in the accessibility addendum.

If there are no sound hazards, use code 16. If the risk cannot be determined, use code 25.

Only for use in ONIX 3.0 or later.
