Severe Hearing Loss:

An FM induction loop should be placed in the classroom of hearing-impaired students or workplace of hearing-impaired employees. The hearing aids may cause headache after a while as the user hears all voices in the classroom as noise and the person may have to take off the device later. The FM induction loop filters the noise in the background and allows the person to clearly hear speeches.

Totals:
 

• There should be typed texts, signboards.
• Illuminated warnings should be used.
• People who know sign language should accompany them.
