Ipsilateral Earphone: is integrated in the probe system
Probe frequency transmitter and receiver and
pressure transducer is integrated in the probe system
Generally the instrument is made and calibrated to be
within and better than the tolerances required in the
specified standards:
±1%
±3 dB for 250 to 4000Hz and ±5 dB for 6000 to
8000Hz
±5 dB for 500 to 2000Hz and +5/-10 dB for 3000 to
4000Hz
±1.5 dB for 1000 to 4000Hz and ±3 dB outside range
±2 dB for click stimulus
±2 dB for all stimulus types
±5% or ±10 daPa, whichever is greater
±5% or ±0.1 ml, whichever is greater
ON-OFF ratio = ≥ 70 dB
Rise time = 27 ms
Fall time = 24.6 ms
A weighted SPL in Off = 31 dB
226 Hz ± 1%, 678 Hz ± 1%, 800 Hz ± 1%, 1000 Hz ±
1%
85 dB SPL ±1.5 dB measured in an IEC 60318-5
acoustic coupler. The level is constant for all volumes
in the measurement range.
Max 1% THD
0.1 to 8.0 ml
-0.00020 ml/daPa
0.001 ml is the lowest detectable volume change
≥95 dB SPL (measured in the 711 coupler, 0.2 ml, 0.5
ml, 2.0 ml & 5.0 ml hardwalled cavities).
Initial latency = 35 ms (±5 ms)
Rise time = 45 ms (±5 ms)
Terminal latency = 35 ms (±5 ms)
Fall time = 45 ms (±5 ms)
Overshoot = max. 1%
Undershoot = max 1%
Values between -600 to +300 daPa can be selected
in the setup.
-750 daPa and +550 daPa, ±50 daPa
