Test Procedure

NOTE: the TEN test is performed ipsilaterally, meaning that the tone and the noise are presented in the
same ear. It can only be conducted with TDH39, DD45 and Insert earphones headphones
Setup:
2
1. Launch the Affinity
2. Ensure you are in the AUD module (click on the AUD tab on right hand side of the screen if not)
1
3. Choose TEN test from the Protocols and sessions drop down menu
4. Transducers: Select the desired transducer and ensure that the stimulus is
directed to the same ear in channel 1 and channel 2 (see below). If testing
the right ear, select Phone right for both channels (see below)
5. Stimulus/Input: Tone for Channel 1 and TEN for channel 2 (see below)
6. Set the masking to Rev to have a continuous masking signal. To stop the masking, click on Man or hover
the mouse over the Stimuli button (see below)
7. Set the intensity levels (Moore, 2009)
- For frequencies where hearing loss up to 60 dB HL: set the TEN level to 70 dB.
- For frequencies where hearing loss is 70 dB or more: set the TEN level 10 dB above the
audiometric threshold at that frequency. For example, if the audiometric threshold is 75 dB HL, set
the TEN level to 85 dB HL.
- If the TEN is too loud, or if the maximum TEN level of 90 dB HL is reached, then set the TEN level
equal to the audiometric threshold. This should still give a definitive result.
8. Conduct a threshold search using the traditional method for air conduction
9. Repeat for each frequency where a dead region is suspected
