Ponto Pro
scores best in independent test
Over the last year, bone anchored
hearing systems have developed considerably.
The benefits of this development were put to test
in an independent crossover study initiated and
conducted by Rigshospitalet in Copenhagen, Denmark.
The two devices being compared were Cochlear’s
BP100 and Oticon Medical’s Ponto Pro.
The statistically significant results of the
study are presented inside.
8 out of 12 preferred Ponto Pro
Compared to the BP100, Ponto Pro excelled on a number
of key parameters, including speech intelligibility and
ease of use. Out of 12 subjects new to bone anchored
devices, 8 declared a preference for Ponto Pro.
Result highlights
Significantly better ratings of speech perception
Based upon trials in daily environments, subjects rated Ponto Pro significantly
better than the BP100 when conversing with one person in a car and when
listening to the TV or radio.

Improved speech intelligibility
In an objective speech in noise test, measurements of speech reception
thresholds (SRT) showed a statistically significant improvement of about 3 dB
in Ponto Pro’s full-directionality mode compared to its omni-directional setting.
This is equivalent to an improvement in speech intelligibility of about 30%.
The speech was presented from a front loudspeaker and the noise presented
from loudspeakers placed at an angle of 90 and 180 degrees.

About the study
12 first-time users of bone anchored hearing systems
tested, in random order, Cochlear’s BP100 and Oticon
Medical’s Ponto Pro sound processors. The subjects
tested each device on average for 34 days in their
daily environment. The sound processors were fitted
according to the manufactures’ fitting guidelines,
and no fine tuning was performed. The processors
were then rated at the end of each test period.
The study was conducted by Steen Østergaard Olsen,
Henrik Glad and Lars Holme Nielsen, Research Laboratory, Department of Otorhinolaryngology, Head &
Neck Surgery, University Hospital, Rigshospitalet,
Copenhagen, Denmark.
The study was conducted with no outside funding or
grants.
