1.1 Intended Use Statement

The ERO•SCAN

®

Hearing Test System is indicated for testing of cochlear function in

infants, children, and adults by measuring otoacoustic emissions (OAEs). This
instrument is suitable for use in all settings, including hospitals, schools, physician's
offices, and audiologist practices. Factory defined protocols allow for simple screening
measurements and user customizable protocols allow for diagnostic evaluations. The
ERO•SCAN

®

is intended to be used by hearing healthcare professionals (i.e. ENT

doctors, audiologists) and/or technicians, neonatal nurses and school nurses who have
been trained by a hearing healthcare professional.

1.2 Indications for Use Statement

The OAEs are generated by a series of clicks that are directed into the ear canal.

Otoacoustic emissions are low level audio-frequency sounds that are produced by the
cochlea  as  part  of  the  normal-hearing  process.  Available  evidence  suggests  that
otoacoustic  emissions  are  generated  by  the  cochlea’s  outer  hair  cells  and  that  the
presence of OAEs is an indication that the outer hair cells are viable. Clinical evidence
indicates  that  these  emissions  normally  occur  with  normal  hearing,  or  at  most,  mild
hearing loss (usually 30-40 dB HL). The majority of hearing-impaired individuals will
be identified by a simple OAE test.

1.3 Contraindications of Use Statement

Testing should not be performed on patients with one of the following symptoms
without a medical doctor’s approval:

•

Recent stapedectomy or other middle ear surgery

•

Discharging ear

•

Acute external auditory canal trauma

•

Discomfort (e.g. severe otitis externa)

•

Occlusion of the external auditory canal

Visual inspection for obvious structural abnormalities of the external ear structure and
positioning as well as the external ear canal should be performed before testing.
