This International Standard does not specify the characteristics of the alerts, such as alarm sounds or emergency signals. NOTE 2 The auditory danger signals are covered by ISO 7731. This International Standard does not specify the characteristics of auditory guiding signals coming from the personal mobile equipment that is worn by persons with seeing impairment and blindness.
