Aparelho Para Emissão Otoacústicas OAE Ero Scan MaicoERO SCAN ProOAE /TympanometryERO SCAN ProThe Ero Scan Pro was the first system that had the capability of linking DP and TE protocols for diagnostic cochlear mapping.An optional impedance function can be added for tympanometry (226 Hz and 1000 Hz), and ipsiIateral acoustic reflexes for an objective evaluation of the middle ear.Features at a glance:- Customizable settings and protocols - Sequenced protocols permit a full test battery - Test patient of any age - Documented test results - Portable hand held unit runs on alkaline batteries - Small footprint to easily move from room to room - Approved, verified protocols can be customized - Open templates that can be customized - Quick print to PC without a full transfer required DPOAE/TEOAE/Tymp and Ipsilateral Acoustic Reflexes - One probe fit; run three tests without taking probe out of the patients ear. OAE, tympanometry and ipslateral acoustic reflex. - OAE and tympanometry can be completed in as little as 20 seconds - Intuitive interface for fast, easy operation - Advanced diagnostic OAE capabilitiesAdvantages of OAE - DPOAE high to low frequency testing - Immediate stop of testing upon pass result - Boys Town normative data included and visible on the hand held unit screen Advantages of Tympanometry: - Evaluates condition of middle ear - Objective test methodTechnical Data DPOAE SystemPrimary Tones: Frequency: F2 from 1.5 kHz to 12 kHz Intensity: Up to 6 kHz: 40/40 to 70/60 dB SPL Over 6 kHz: 40/40 to 65/55 dB SPL MIC System Noise: < -20 dB SPL at 2 kHz (1 Hz Bandwidth) Artifact: < -20 dB SPL at 2F1-F2 Frequency F1/F2 Ratio: 1.2 (default) adjustable 1.1 to 1.4 F1/F2 Differential: 0 to 30 dB SPL TEOAE SystemStimulus: Adjustable up to 83 dB SPL Broadband Click Click Bandwidth: 500 Hz to 4000 Hz Analysis Bands: 6 or 10 Bands Artifact: <-10 dB SPL Acoustic Reflex SystemStimulus: 500, 1000, 2000, 4000 Hz Pure tone Broadband noise, low pass noise, high pass noise Probe Tone: 226 or 1000 Hz Stimulus Intensity: 500-4,000 Hz 70-95 dB HL, in 5 dB steps Noise stimulus 60-90 dB HL, in 5 dB step Standards: IEC60645-5; ANSI S3.39-1987Tympanometry SystemProbe Tone Frequencies: 226 Hz, 1000 Hz Probe Tone Level: 85 dB SPL with in-ear calibration Air Pressure Range: 0.05cc to 3.0cc: +300 to -400 daPa 3.0cc or greater: at least +200 to -200 daPa Air Pressure Capacity: 0.05cc to > 5.0 cc Air Pressure Speed: 60 daPa/sec. nominal 500 to 700 daPa/sec (depending on ear volume) Test Time: 2.5 seconds nominal (depending on ear volume) Overpressure Limit: 1.0cc ear canal volume < 3 psi (2000 daPa)STANDARD ACCESSORIES- Eartip kit - Cradle - USB - OAE external probe - Probe tips (internal) - Probe tips (external) - Operation manual OPTIONAL ACCESSORIES OPTIONAL ACCESSORIES- Printer - Carrying case - Tymp/OAE external probe - Patient management software
