WHICH ACOUSTIC NOSEPIECE?
There are two types of nosepiece supplied with the acoustic system. Two sizes of anatomical
(medium and large), and one size of conical (8mm). The anatomical nosepieces are handed,
i.e. one is for use on the right side (marked D and coloured red) and one for the left side
(marked S and coloured blue). The conical nosepiece can be used on either side.
ANATOMICAL AND CONICAL ACOUSTIC NOSEPIECES
The choice of nosepiece depends on which will give the best seal between the nosepiece
and the nose, with the least
distortion.
The choice of nosepiece depends on
which will give the best seal with the
least distortion.
The conical nosepieces are suitable
for use with a nose which has a small
round opening, while the anatomical
nosepieces are designed to sit on the
outside of a nose with a long narrow
opening, and are shaped to make it
easy, in most circumstances, to get a
good seal. In addition, they have a flange which a soluble gel can be put onto to reduce any
remaining gap
.
CHILD NOSEPIECES
The nosepieces supplied with the
child sound tube
are 4.5 cm long and are manufactured from
silicone rubber. As the wall thickness is 1.5 mm it is possible to run a bead of gel around the
end of the tube, which will help obtain an airtight connection to the nose. Alternatively, an
additional washer can be added to the end of the child nose piece to increase the width where
gel can be added.
