3hours to charge 90%Ģ50 OAE tests or 100 ABR tests per charge, 8hours typical use, 1 week intermittent useĢ78mm x 84mm (widest point, 66mm at handgrip) x 66mm (11in x 3.3/2.6in x 2.6in)ĭata connector to USB 1.1/2. This aspect of the device is of particular interest to Audiologists, Ear, Nose and Throat specialists, Neurology specialists and other health professionals concerned with the differential diagnosis of hearing problems, the monitoring of changes to hearing, the conservation of hearing or the detailed measuring peripheral auditory function.Ģ x 16bit analogue. These functions are intended for use as a part of the audiological diagnostic test battery, not as a solitary diagnostic test. The TEOAE and DPOAE analysis functions of the device are also indicated for clinical audiological investigations when objective non-invasive characterisation and monitoring of the functional status of the peripheral auditory function is required. The screening functions of the device are suitable for operation by trained screeners without specialized knowledge. A quiet room is required and the patient should be very quiet and still during the test. The device can be used in a wide range of different environments for example in the well-baby nursery, the NICU, a doctor’s office, an audiology clinic, the outpatient clinic or in the home. Fast, accurate and automatic pass/refer result with low cost consumables and long battery life all make the Otocheck DP the ideal way to screen with DPOAEs. ABR waveform identification (Template Correlation) is optimised for infants from 34 weeks to 6 months gestational age but template-free pass criteria for ABR may be selected for use with patients outside this age range. The Otocheck DP is an easy and simple to use handheld DPOAE system with an intuitive interface for both paediatric and newborn hearing screening. Its use is also indicated in populations of any age where objective evidence of normal peripheral auditory function is required. The device is especially indicated when the patient is unable to give reliable voluntary responses to sound, for example with infants. The device provides evidence of normal peripheral hearing function objectively and non-invasively. The instrument uses the Distortion Product Otoacoustic Emissions (DPOAE), Transient Evoked Otoacoustic Emissions (TEOAE) and Auditory Brainstem Response (ABR) technologies. Its use as a screener is indicated when there is a requirement to screen for hearing disorders. The Otodynamics Otoport/Otocheck OAE+ABR device is a handheld hearing test device.
