Many deaf people use a Silent Call system that automatically picks up things like fire alarms, and door bells, which it transmits to a flashing light/vibration receiving unit that the person keeps with them.

Why are smoke alarms so loud that it hurts my ears?

Smoke alarms are designed to be loud in order to alert people to potential danger and ensure they hear the alarm even if they are asleep or in another part of the house. While the high decibel level may be uncomfortable or even painful, it is necessary to grab attention and prompt immediate action in case of a fire. The priority is to ensure people's safety by making sure they can hear the alarm even in noisy or chaotic situations.
