1.7.5.2 Word Recognition (WR) in table mode

The Word Recognition score determines the patient’s discrimination ability expressed in a percentage. It

provides information about what phonemes the patient has difficulty hearing at a particular intensity level.

This is helpful for counselling and rehabilitation purposes. The diagnostic value has shown to be fairly low

but it is generally accepted that the word and sentence recognition are least affected by conductive and most

affected by neural loss.

There are numerous ways of performing the WR. The procedure described below is a suggestion.

1) Perform air and bone conduction audiometry as described in section 0 and 1.6.3 in order to obtain

the PTA.

2) Open the Speech Screen

3) Ensure that WR test is active.

In table mode, this is shown by the corresponding WR label being orange

4) Choose the input for channel 1 (Microphone, CD or wave file). In case of wave files, select the

preferred material and wordlist (see below). Note that calibration is the same for SRT (see section

1.6.5.1 above).

5) Start in the better hearing ear according to the audiogram and set the intensity to approximately 30

or 40 dB above PTA (minimum 55 dB). In cases where recruitment is present start lower at about 20

dB above PTA and ask the patient if the level is comfortable after 2-3 words.

6) Begin presenting the speech material. Use the scoring buttons to score and store the results. The

current score (in percent) will appear in the black bar.

7) Upon changing Transducer, Masking, and/or Aided re-testing an additional WR entry will appear in

the WR table. This allows for multiple WR measurements to be shown in the WR table

8) If you have other speech audiograms on the patient saved in Noah or OtoAccess™ you can

compare the new audiogram to a previous one using the session list. This is done by using the

checkboxes of the historic sessions that you like to overlay.

To save the audiogram press Save

or Save and Exit .
