3.2.2 Speech audiometry in table mode
The AC440 Table Mode consists of two tables:
1) The SRT (Speech Reception Threshold) table. When the SRT test is active, it is indicated in orange
There are also options to conduct speech audiometry to find MCL (Most Comfortable Level)
and UCL (Uncomf ortable Loudness Level), also highlighted in orange when acitivated:
2) The WR (Word Recognition) table. When WR1, WR2, or WR3 is active the corresponding label will be
orange
The SRT table
The SRT table (Speech Reception Threshold table) allows for measuring multiple SRTs using diff erent test
parameters, e.g. Transducer, Test Type, Intensity, Masking, and Aided.
Upon changing Transducer, Masking, and/or Aided and re-testing, an additional SRT entry will appear in the
SRT table. This allows for multiple SRT measurements to be shown in the SRT table. The same can be
applied f or when performing MCL (Most Comfortable Level) and UCL (Uncomf ortable Loudness level)
speech audiometry.
Please refer to the Affinity2.0/Equinox2.0 Additional Information document for more inf ormation about SRT
testing.
