DESKTOP DEVICES:
Senti Desktop and Senti Desktop Flex differ in sockets. Senti Desktop offers jack plugs and
is calibrated to a specific headphone and/or bone conductor. Senti Desktop Flex offers the
ability to exchange different calibrated transducers. Sentiero Desktop offers the same modules as
Sentiero together with the ability to conduct tympanometry and acoustic reflex measurements.
1.3 Intended Use
Devices of the Senti and Sentiero device families offer different test methods which can be
configured to fit the professional's needs for hearing screening or diagnostics. Devices of the Senti
device family provide multiple psycho-acoustic test procedures including conventional and image-
based pure-tone audiometry (e.g. Audio, MAGIC) and speech tests (e.g. SUN, MATCH). Devices of the
Sentiero device family additionally provide physiological test procedures including transitory evoked
otoacoustic emissions (TEOAE), distortion product otoacoustic emissions (DPOAE), auditory
brainstem responses (ABR; Sentiero Advanced only), auditory steady state responses (ASSR; Sentiero
Advanced only), and auditory impedance and acoustic reflex measurements (Sentiero Desktop,
Sentiero and Sentiero Advanced with tympanometry add-on).
Available psycho-acoustical methods on Senti and Sentiero are especially indicated for use with
cooperative patients starting at the age of two years or adequate development age, which enables
them to do play/interactive audiometry. All other physiological modules are suitable to be used for
all ages elder than infants from 34 weeks (gestational age) that are ready for discharge from the
hospital.
All physiological test methods are especially indicated for use in defining the type and configuration
of hearing loss particularly for individuals whose behavioral audiometric results are deemed
unreliable or to assist in the diagnosis of otologic disorders. Estimation of cochlear hearing thresholds
(DPOAE Threshold) is possible at various frequencies without the need of cooperative interaction
with the patient. Acoustic reflex and tympanometry are featured to evaluate the functional condition
of the middle and outer ear. For each method, several protocols can be configured. The results can
be used to make further recommendations regarding appropriate intervention strategies.
Devices of the Sentiero device family are intended for the following purposes:

Diagnostics, monitoring and follow-up after newborn hearing screening

Pre-school, school, and adult hearing screening

ENT diagnostics based on measurement of
a) Otoacoustic emissions
b) Tympanometry and acoustic reflex (Sentiero Desktop, Sentiero and Sentiero
Advanced with tympanometry add-on)
