The Littmann Electronic Stethoscope Model 4100 features amplification
and proprietary Ambient Noise Reduction (ANR) technology allowing you to
reduce ambient noise by an average of 75% (-12dB) without eliminating
critical body sounds. Three frequency modes are available for listening
to heart, lung, and other body sounds: Bell (20-200 Hz), Diaphragm
(100-500 Hz), and Extended Range (20-1000 Hz).
In addition, digital signal processing
offers recording, storage, and playback capabilities, as well as the
ability to transfer recorded sounds via an infrared transmission to
another Model 4100 or Model 4000 or IBM-compatible computer or hand-held
device.
When combined with the 3MT Sound Analysis
Software you have an exquisite, state-of-the art auscultation system,
which allows you to see what you are hearing via visual display of a
phonocardiogram . This "hardware" and "software" combination will
enhance teaching opportunities, serve as a diagnostic aid and help you
make more effective use of telemedicine.
A
trusted leader in innovative auscultation technology, Littmann
stethoscopes are renowned worldwide for unsurpassed quality. Since 1963,
the Littmann brand name
has been the assurance of precision, acoustical superiority, innovative
design and
exceptional performance.
