The ER36 Series OAE Test System is indicated for testing of cochlear function in infants, children, and adults by measuring otoacoustic emissions (OAEs). The OAEs are generated by a series of clicks or tones 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 OAE's 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 30-40dB HL). The majority of hearingimpaired individuals will be identified by a simple OAE test.

The ER36 Series OAE Test System is a battery powered, hand-held microprocessor-controlled instrument designed to measure otoacoustic emissions. The ER36 is connected by a 1 meter, thin flexible cable to the ER36 MicroProbe OAE Test Probe (Ear Probe). The Ear Probe incorporates a field replaceable Probe Tip (9-lumen tube) that is inserted and acoustically sealed to the test ear canal with a compliant ear tip. The ER36 provides otoacoustic emissions measurements by two methods: distortion product otoacoustic emissions (DPOAE), and transient-evoked otoacoustic emissions (TEOAE). The OAEs are generated by a series of clicks or tones 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.

The ER35 ERO•SCAN Pro Hearing Test System is indicated for testing of cochlear and middle ear function in infants, children, and adults by measuring otoacoustic emissions (OAEs), tympanometry, and acoustic reflex.

The ER35 is a microprocessor-controlled instrument designed to screen otoacoustic emissions, tympanic membrane performance, and acoustic reflex. Test information is stored in memory, displayed on a graphic LCD, and can be printed by a printer or stored on a computer. The product is manufactured and delivered completely assembled to the retailer using materials and techniques widely used by manufacturers of hearing devices.
