Inclusive Design for Hearing Impaired Users

Cambridge AS Design & Technology students produce a coursework project that improves an existing product. This article includes a list of ways that products can be modified to be more inclusive for users with deafness and hearing impairments.

Boost visual communication:

• Provide captions for all audio content – use written words to explain things (i.e. airports provide screens with boarding information in addition to saying it over the loudspeaker)
• Use visual indicators instead of audio alerts (flashing lights, on-screen notifications) – i.e. microwaves that flash lights upon completion, or smoke alarms with flashing strobe lights alongside audio alarms
• Position visual features where they are immediately noticed – provide clear sight lines
• Provide good lighting for lip reading and sign language

Use vibration to communicate

• Washing machines that vibrate upon completion
• Use vibration patterns for notifications and alerts on digital devices

Make audio adjustable

• Provide volume controls and amplification options, with adjustable settings to accommodate different types of hearing loss
• Ensure compatibility with hearing aids and assistive listening devices
• Provide audio transcripts as backup

Reduce background noise

• Use materials that absorb background noise and reduce echo

The core aim is to ensure that any information conveyed through sound can also be communicated by sight or touch, while also enhancing audio when possible for those with partial hearing.
