DP-OAE
Product catalog summary
System Overview: The PC-module with a microprocessor controller and USB 2.0 port is designed for use with a Pentium PC (minimum 500 MHz) and compatible with Windows 98, ME, 2000, and XP. It adheres to standards EN 60601-1, 1-1, 1-2, MPG, and NUB rules.
Specifications: The device operates with stimulus frequencies ranging from 562 Hz to 9,843 kHz and intensity levels from 0.5 dB SPL to 70 dB SPL, adjustable in 0.5 dB steps. It features a miniature probe with pressure ventilation and semi-automatic self-cleaning, controlled via a best-fit-test and real-time control view.
Functionality: The system supports averaging of sweeps in time or spectral areas and presents results in a DP-graph showing signal, noise, and spectrum. It evaluates hearing loss using input/output functions and slope analysis, with options for DP 1 = 2F1 - F2 or DP 2 = 2F2 - F1.
Design and Accessories: The device measures 290 x 250 x 75 mm and weighs 1.8 kg, with a probe weight of 12 g. It includes a 2000 mm flexible probe cable, a power pack (+13.2 V, 15 W), a miniature probe, 30 earplugs in five sizes, an external power pack, a USB cable, a program CD, and an instruction manual.
Clinical Application: The DP-OAE 4000 is used for diagnosing sensorineural deafness through T-OAE and DP-OAE measurements. It is suitable for all age groups and is particularly effective for early detection of hearing loss in children and newborns. The device covers a wide range of diagnostic needs with its ability to test multiple frequency areas and its 'Hearingloss-Mode' for assessing hearing loss when traditional audio tests are not feasible.
Advanced Features: The system includes methods to suppress artifacts and unwanted responses, such as adding a third frequency (f3) and setting output in phase relation to the input signal. Results are displayed in various diagrams, including a 3-D graphic for comprehensive analysis. Data is stored on the computer's hard drive, and the system can integrate with other HOMOTH diagnostic modules.

DP-OAE 4000 Lately the Otoacoustic Emissions (OAE) have become more and more important in the field of objective diagnosis at sensorineural deafness. Using the T-OAE measurement (Transient Evoked Otoacoustic Emissions) clicks will cause a wide-band-irritation, using the DP-OAE´s specific frequencies for irritation, (Distorsion-Products Otoacoustic Emissions) it is possible to provoke, measure and evaluate frequency related parts of the cochlear. A sound proof cabin is not necessary, only a noise-reduced area. By continuous stimulation with two presetable primary sinus tones(f1, f2), the selected...
