IMPORTANT NOTE for Hearing Impaired Users.
Please be aware that using the E-Scope with your hearing aid
for auscultation of the heart, lungs or Korotkoff (blood pressure)
sounds may be limited by the capability of your hearing aid or
the interface between your hearing aid and the E-Scope
Electronic Stethoscope.
Heart Sounds have a frequency range of 20-650Hz while
breath sound range form 70 to 2000Hz.
Hearing aids are designed for enhancement of voice sounds
that have a frequency range from approximately 500 to
4000Hz. Some hearing aids can be programmed for lower
frequencies. However, even with this additional low frequency
response, the hearing aid may still not be able to reproduce the
heart and lung sounds adequately for diagnosis. Also, some
individuals may have hearing loss in the range for heart and
lung sounds that is not compensated by their hearing aid. For
these reasons, Cardionics recommends that you consult with
your audiologist for advice covering your hearing loss and the
response of your hearing aid.
We will be pleased to assist you or your audiologist.
