The geometry of the acoustic chamber – perfected over decades – in combination
with the modern ERKA. dual membrane provides optimal auscultation over
the entire frequency range. The auscultation is optimized by the high specific
gravity of the brass body, as this reliably prevents noise interference.

1_ The construction of the patented ERKA. dual-membrane allows for an
additional resonance chamber which optimizes the sound.
2_ The non-chill ring ensures patient comfort and protects the membrane.
3_ Highly polished and chromium-plated for a non-porous surface, the brass
chest-piece ensures perfect surface hygiene.
4_ Through the separately integrated spring in the tube, there is no acoustic
loss from the chest-piece to the ear.
5_ The ergonomically designed, super soft ear tips create an excellent acoustic
seal against external noise interference and maximize wearer comfort and fit.
6_ The standard 15° inclined binural can be individually adapted to the ear
canal characteristics of the user.
