Lesson 25 : Designing Interiors for the Hearing Handicapped

Physical Layout

In general terms, hearing impaired users benefit from simple, straight forward design and layout. However, large open plan spaces can be difficult to hear in as sound often reverberates. Breaking spaces up into smaller "capsules" by the use of portable screens may prove helpful as this isolates sounds and reduces distracting background noise and interference. Avoid the use of hard surfaces, especially on floors as sound "bounces" off them making it difficult to hear. Other sounds, such as chairs and tables being moved, are amplified. Even the sound of footfalls can seem distractingly loud to a hearing aid wearer. Hearing aids pick up and amplify all sounds that surround the wearer, not just the sounds they wish to hear. Use of carpet in walkways helps to reduce reverberation.
