Summary
48 SLS loop systems have been installed in all public spaces in a home for elderly
people in Finland. Despite a problematic installation the project was successfully
completed resulting in higher accessibility for the hearing impaired residents.
Case Study
Home for the elderly,
Kontula, Finland
Challenge
To make it possible for hearing aid users to enjoy music, watch TV and listen to a sermon
or lecture without interfering with each other. The building has seven storeys including
basement and the rooms to be covered were often situated above/below each other.
Solution
As the rooms often were either adjacent or above/below each other it was rapidly
decided to install SLS loop systems throughout the house. The first plan was to
install the loop wires using thin copper foil directly beneath the linoleum carpet.
After tests this solution was abandoned as the contours of the copper foil were
visible under the carpet. As a result the loops had to be installed in a suspended
ceiling about 2.4-2.8 meters above the floor. This made the installation process
more complicated and wooden bars had to be used to attach the copper foil across
the metal network of the suspended ceiling. The ceiling height (between 3.7 and
4.6 meters) and the exceptional overspill control built into the SLS system made
it possible to finalize the installation successfully with a signal-to-noise ratio good
enough to allow simultaneous use of the loops.
Conclusion
The result was that all public areas, ranging from 25-120m2, were made accessible:
dining rooms, cafeterias, TV rooms, gyms, meeting rooms and several halls. Also
the chapel was covered and for any other space or for outdoor use a portable
loop system was purchased. This portable loop system can also be used during
excursions.
