| Software More information about the tailor made Isometric Software that works in conjunction with Ultra Stethoscope
and the third party Picoscope Software; which is available from Pico Technology. Isometric software for a period of 6 months is supplied free of charge with a purchase of each
Ultra Stethoscope. + Isometric Software used in conjunction with Ultra Stethoscope
 Output displayed with tailor made isometric software using an Apple computer. Frequency
components of audio signals generated by the Ultra Stethoscope are shown.
The software is also available for Mac.
Isometric Software used in conjunction with Pico Scope Output from the Ultrastethoscope can also be captured and displayed by using PC - based
instrumentation and data aquisition produced by Pico Technology, St Neots, Cambridgeshire PE19 8YP.
 The traces aim to allow the user to demonstrate any abnormal sounds. The switchable filter on
the stethoscope body limits the sensitivity of the device to unwanted environmental noise [ i.e. that coming from
sources such as lighting, heating pipes, refrigerators and pumps ]. The traces allowcomparison of data obtained
serially. Careful examination of trace qqq shows that instead of a single peak there are sometimes three close together.
In early versions of the stethoscope such traces were common. Investigation showed that these were
due to sound reverberation in the conical capture volume
and this problem has now been eliminated by careful design changes.
 Continually being improved: This is a recording of heart sounds made with an early version of the
Stethoscope before we introduced features to remove the double and triple peaks which are believed
to be artefacts caused by sound reverberations. _ |
