11.2 Technical specifications EP15/EP25/VEMP
Medical CE-mark:
The CE-mark indicates that Interacoustics A/S meets the requirements of Annex II of the Medical
Device Directive 93/42/EEC.
Approval of the quality system is made by TÜV – identification no. 0123.
Standards:
Test Signal:
IEC 60645-3, 2007
AEP
IEC 60645-7, 2009. Type 1
EPA Preamplifier:
Two channels standard
EPA4 Cable Collector (4 electrodes). Standard 50 cm. Option: 5
cm or 290 cm
One Channel (optional)
EPA3 Cable Collector (3 electrodes). 50 cm
Gain:
80 dB/60 dB
Frequency response:
0.5 – 11.3kHz
CMR Ratio:
Minimum 100 dB. Typical 120 dB @55 Hz
Radio frequency immunity:
Typically 20 dB improvement over previous available designs
Max input offset voltage:
2,5 V
Input impedance:
10 MΩ/ 170 pF
Power from main unit:
Insulated power supply with 1500 V isolation. The signal is
digitally/capacitive insulated.
Specifications as EPA4
Impedance measurement:
Selectable for each electrode
Measurement frequency:
33 Hz
Waveform:
Rectangular
Measurement current:
19µA
Range:
0.5 kΩ – 25 kΩ
Stimulus:
Stimulus rate:
0.1 to 80.1 stimuli per second in steps of 0.1.
Envelopes/Windows :
Bartlett, Blackman, Gaussian, Hamming, Hanning, Rectangle and
Manual (Rise/Fall and Plateau)
Masking:
White noise. Calibrated and presented in peSPL.
Transducer:
Ear Tone ABR insert phone, calibrated on an IEC 711 coupler.
Headphone with independent calibration (optional)
Bone conductor (optional)
Level:
20 – 135.5 dB peSPL, (-10 – 100 dB nHL) in 1 dB steps.
Polarity:
Condensation, Rarefaction, Alternating.
Click:
100 µs (200Hz -11kHz)
Tone Burst Frequency:
250, 500, 750, 1000, 1500, 2000, 3000, 4000, 6000 and 8000 Hz.
Tone Burst Stimulation
Time:
Stimulation up to 780 ms
NB CE-Chirp® LS Freq.:
500, 1000, 2000 and 4000 Hz
Broadband CE-Chirp®: LS
200Hz -11kHz
Relative Masking Level:
+30dB to -40 dB relative to stimulus level. The stimulus level is
presented in nHL. The masking level is only presented in SPL,
and can therefore not exceed the loudness of the stimulus. E.g. a
stimulus presented at 100dBnHL, and relative masking level at
0dB would provide a masking level of 100dB peSPL. This would
equal a level 75dBnHL.
