3.5.5 Weber

The Weber test distinguished between conductive and sensorineural hearing loss through use of a bone
conductor. Use the indications to show where the tone is perceived. If the patient hears the tone better in
the poorer ear the hearing loss is conductive, and the tone is heard better in the better ear the hearing
loss is sensorineural at the given frequency.
The symbols for Weber correspond with the soft buttons:
Percieved right Percieved center Percieved left Not heard No reaction

3.5.6 Pediatric Noise Stimuli

This Pediatric Noise stimuli is a narrow band noise signal that is designed with very steep filter slopes.
Pediatric noise stimuli replaces the use of the narrow band masking noise as a stimulus for threshold
assessment – in particular for pediatric testing and in sound field (e.g. using VRA). When the pediatric
noise stimuli is selected, the Warble light indicator (25) will blink.
