- A3.07.1An alarm that can't beat the noise of its deployment site fails before design even starts
- A3.07.2Hearing an alarm is not the same as telling which alarm it is
- A3.07.3An alarm system with more signals than anyone can remember stops meaning anything
- A3.07.4Faster tempo and rising pitch can signal growing urgency without inventing a new timbre
- A3.07.5A sound with no natural link to its meaning must be learned; a resembling sound travels across languages
- A3.07.6When several alarms fire together they can drown each other out unless one takes priority
- A3.07.7A shared alarm sound speeds recognition across systems; a custom one tells contexts apart, not both
