1.5 Full 2(4) channel Speech in noise

The ability to test via Full 2(4) Channel Speech in noise allows the ability to test whilst stimulating speech
and noise in both channels at the same time.
If the R+L is chosen in channel 1 the level presented in Channel 1 will be equal in both Left and right
transducer at the same time and vice versa. When this is enabled the Audiograms will both be coloured grey.
Channel 1 serves as the stimulus in this instance and channel 2 serves as the masking. This will be
presented to both ears simultaneously, therefore alteration of frequency or intensity is applied binaurally.
When the R+L is activated the stored symbol will be shown as a "B". See below:
If it is used in speech mode it will be stored equally to the binaural mode, as mentioned above.
When the R+L is activated in the speech section and displayed via the table mode both results will be
stored even if the level is different. This results in second channel data being stored at the same time.
The table screen is split up in two which means the transducer and the stored level is shown for channel 1
first and then channel 2. See below:
