What type of device is used to replace doorbells, alarms, etc. for accommodating hearing loss?

Assistive hearing devices are specifically designed to enhance the auditory experience for individuals with hearing loss. These devices often include alert systems that are used to replace or supplement traditional doorbells and alarms, using visual or tactile signals instead of sound. For instance, a vibrating doorbell can alert a person with hearing loss through a gentle shake of the device or by flashing lights, making it much more effective than sound-based alerts.

The other options refer to broader categories or methods related to hearing loss but do not specifically address the kinds of devices used for alerts or environmental sounds. Cued speech is a method of communicating that involves hand signs to clarify spoken language; it does not pertain to devices for alerting. "Hard-of-hearing" denotes a classification of individuals who experience hearing loss but lack specifics about tools used. The term "deaf" refers to individuals who have profound hearing loss and also does not imply any specific alerting devices. Thus, assistive hearing devices are the most appropriate choice for this context.
