5.1.11 Langenbeck
The Langenbeck noise audiometry investigates the hearing threshold of pure
tones while masking noise is presented simultaneously to the same ear with a
constant level for all frequencies. The tone in noise hearing threshold is typically
as high as the level of the noise. The noise has a higher influence to neural
hearing losses and the tone in noise hearing threshold will be increased. Set the
signal of the first channel to tone and the signal of the second channel to noise
and route both channels to the same ear. Set the level of the noise to a fix value
and test the hearing threshold.
