Air-bone gaps are the difference in sensitivity threshold between air and bone conduction transducers. This measurement helps distinguish between conductive and sensorineural hearing losses, as well…
I wanted to know whether the Eclipse can be used to do ABRs on children that are not sedated (e.g. a 4-year old looking at an iPad). Is sedation essential with children when using the Eclipse? Answer…
The regular ABR stimulus is in dB nHL and the masking in dB SPL. How do we know if the levels are comparative? In other words, if the AC toneburst is 40 dB nHL and the masking intensity is 45 dB SPL…
Both of these auditory evoked potentials responses arise from generators in the thalamo-cortical region of the central auditory system and so you would associate them with objectively assessing thres…
The prefix “nHL” conventionally refers to sound level (dB) of a signal referenced to the thresholds for a group otologically normal hearing people – it is the same concept as dB HL, however nHL is of…
My Interacoustics distributor suggested I get these green jump leads but I’m not sure what they are for? Answer: These connectors are extremely useful so we say you have made a very wise purchase her…

In this quick guide, you will learn how to setup and use Interacoustics’ dedicated Audiometer Keyboard. The Audiometer Keyboard supports clinicians who wish to use a dedicated keyboard to perform aud…
This guide is valid from Titan 3.5. The Titan IMP440 WBT software comes with a possibility to export data to Matlab from the Wideband tympanometry tests. Here only the WB Absorbance and the 3D Tympan…
Electrical Evoked Stapedial Reflex Thresholds (eSRT) can be a very useful objective measure for the upper stimulus levels during the programming of a cochlear implant (Brickley et al., 2005; Buckler…
