Test procedure

There are output, input, stimulus level, and stimulus presentation controls for channels 1 and 2. In the top-middle there is a percentage speech score and word counter, below which the user can score the responses, in this example number of correct phonemes from zero to four. To the right there is the patient’s audiogram and pure tone average. The main part of the screen is the speech audiogram, displaying speech recognition and speech detection as a function of dB HL. — **Figure 1:** Speech audiometry test screen.

Before performing speech audiometry, you may wish to perform pure tone audiometry. This provides valuable predictive information useful in speech testing, including information about when masking is needed.

Once you’ve entered the speech test, select the intensity level for channel 1. If masking is needed, configure channel 2 also.

Explain to the patient that they will now hear some words/numbers/sentences through the transducer of choice. Instruct the patient to repeat what is said even though it may be very soft.

Patients may also be encouraged to guess if they are unsure about the word/number/sentence. If performing the speech test in noise, instruct the patient to focus on the speech and not the noise.

Press play to start presenting the words, numbers or sentences.

Based on the settings for speech, the response can be scored as correct, incorrect, or as the number of correct phonemes.
