Interpreting Printed Results
Results from the ERO•SCAN
®
can be transferred to a portable thermal printer or the
ERO•SCAN
®
Database Software for a full page printout. The information, as specified in
section 14.1 and 14.2, is included on both printouts. For instruction on printing from the
database, see the ERO•SCAN
®
Database Software Manual.
14.1
Understanding the DPOAE Printout
The following information is provided for each test (Figure 14):
1)
The software version number (e.g.: V100.01)
2)
The time and date of the test, based on the setting of
the internal clock; if the clock is set correctly, this time
and date will be correct
3)
The test number (if operating in “Save 250” mode)
(e.g.:001)
4)
The protocol selected (e.g.: DP 4s)
5)
The averaging time used for this test (e.g.: 4 sec avg.)
6)
Instrument/Probe serial number (SN)
7)
The ear selected (Right or Left)
8)
A PASS/REFER indication if there is a criterion set for the
selected protocol
9)
The open blocks indicate the noise floor in dB SPL
10)
The solid blocks indicate the emission level in dB SPL
11)
The f2 frequency in kHz (e.g.: 2.0, 3,0, 4.0, 5.0)
12)
The level of the emission in dB SPL (DP)
13)
The noise floor in dB SPL (NF)
14)
The signal-to-noise ratio (SNR) = DP – NF
