Technologies is proud to showcase how such a small package can
bring about such impressive results. The technical advantages
in Clarity Aloft headsets are illustrated in the charts provided.
From the speakers, the boom microphone, to the viscoelastic foam
tips inserted in the ear canal, Aloft Technologies is committed
to quality.
The Earpieces – A two part wonder: The Speaker and
the Foam Tips
The Foam Tips
The patented Comply™ Canal Tips were initially created for
the communication needs of hearing aid users. This advanced technology
has been adapted for use in aviation by Aloft Technologies under
the guidance of Dr. Bob Oliveira, who developed this technical
achievement. The viscoelastic polyurethane foam offers impressive
characteristics based on scientific research and development conducted
by Hearing Components, Inc. in Oakdale, Minnesota. They are licensed
under U. S. Patent nos. 4,880,076 and 5,002,151 and their international
equivalents.
Tests conducted by the US Army have proven that this unique method
of Viscoelastic Passive Noise Reduction (VPNR) results in hearing
protection equal to or better than Active Noise Reduction. The
same earpieces used in Clarity Aloft headsets have been used in
military helicopters in practical application for hundreds of
thousands of hours.
The viscoelastic foam tips have unique capabilities that transfer
well to aviation needs. For example, the tips are designed to
be squeezed, inserted in the outer ear canal and allowed to expand
slowly at body temperature, conforming precisely to the outer
ear canal of each user in a custom fit. Although the customary
use is similar to the simple foam earplugs found in most pilot
shops, the performance characteristic of the foam tips are dramatically
better as evidenced by the chart provided.
Speakers
The speakers used in Clarity Aloft headsets are derived from the
highest quality dual balanced armature transducers used in a variety
of advanced high-end hearing aids. They are designed for very
flat frequency response over a wide frequency range. The sound
is transferred to the ear through a central sound pathway in the
foam. The foam tips are attached to the speaker by a simple threaded
screw mechanism and are easily removed. The earpieces also have
the same proven successful history in use in military helicopters.

Microphone
The microphone used in Clarity Aloft headsets have distortion
free, flat frequency response that produces clear audio over the
entire range of speech frequencies. The audio output of this microphone
far exceeds the capabilities of most other aviation-based microphones.
