People with disabilities have special needs for active participation in daily life. This applies not only to people with reduced mobility but also for people with reduced sensory perceptions.
A sensory access to places and use of buildings is a basic and critical demand for everyone.
To ensure the access to buildings for people with disability, especially Deaf and Hearing-impaired or Hard of Hearing, we need to clarify different aspects of each specific user. Specifically, architecture and daily situations have to be considered separately between the Deaf and Hearing-impaired due to their different needs.
The Deaf are hardly able to hear or just recognize the smallest frequency ranges so daily communication and other activities heavily depend on their visual sense.
The Hearing-impaired or Hard of Hearing have a limited hearing capacity in specific frequency ranges so they need particular personal hearing equipment for sound comfort and acoustics solutions.
Not only sensory access architecture but also daily helper solutions are divided to improve an access environment for all, especially Deaf and Hearing-impaired or Hard of Hearing.
