flooring
gienic benefits of a hard surface with the acoustic and
ergonomic attributes associated with carpets or other
textile surfaces. These materials offer high levels of
sound absorption and reduce surface noise while providing supportive cushioning underfoot to drive safety
and comfort. Adding a new dimension in healthcare
finishes, these resilient flooring options are helping to
create more comfortable and effective healing environments for patients and providers.
IN-ROOM SOUND

All exposed finishes within a room, including flooring,
can affect the speed and efficiency with which sound
travels. Surface-generated sound measures the level of
sound within the same room produced by an impact on
the surface.
For example, the surface-generated sound of a medical
cart being rolled across a porcelain tile floor is very different and generally louder than the same cart moving on a
rubber mat. By selecting the right surfacing, a floor can
help to contain the sound and vibration to more comfortable levels.
To compare the effect of different flooring materials

Hartford Acoustics (West Hartford, CT) program in
2014 conducted an independent research study titled

Noise Levels in Health Care Facilities." Two senior
acoustical engineering students chose this topic for a semester-long research project. It aimed to quantify the
influence different flooring materials can have on hospital corridor noise.
While there are many noise sources within a hospital, one potentially significant source can come from
the hallways and corridors where regular traffic can include footfalls from staff and visitors and rolling noises
from medical carts and gurneys. The Hartford researchers recognized that addressing these noise sources could
positively affect patient-room acoustics.
The students conducted three different tests on each
material: an absorption test (ASTM C423), a tapping-machine test, and a rollin- cart test. The materials
tested included carpet tiles with a rubber backing, sheet
vinyl, sheet vinyl with a rubber backing, virgin rubber
sheet, and virgin rubber sheet with a rubber backing.
Three of these featured Ecore (Lancaster, PA) technology, whereby a wear layer is fusion-bonded to a recycled rubber backing. The goal was to determine how
effective this technology is in reducing noise when added to vinyl and rubber surfaces and to compare these
results with standard commercial floors, such as carpet
and other traditional resilient sheet products.
The study found that when the rubber backing was
combined with vinyl surfacing, it was as quiet as commercial carpet when rolling a medical cart across a room
or with standard footfall, yet more conducive to meet-
