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…
The HiLo CE-Chirp® is a stimulus which is used in automated ABR or ABRIS (auditory brainstem response infant screening). Hearing screening programs typically recommend to screen hearing initially usi…
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…
How much masking should we use in this ABR case example? We tested a 7-month old baby with a bilateral conductive hearing loss. We wanted to check whether we need to mask or not. The not-masked heari…
For caloric testing, I am just thinking if we can do cold or warm water alone, why we need to do bithermal beside the benefit of better averaging. Answer: Well your question already encapsulates one…
This video demontrates a live recording of the ocular VEMP, and the identification of the biphasic response, and the marking of the waveform. Transcript Darren Whelan: Now that we have our patient pr…

In May 2023, the Global Foundation for Children with Hearing Loss (GFCHL) launched a multi‑year pediatric program in Nepal. With Interacoustics equipment donated by the William Demant Foundation and…
This video provides a description of how the Optokinetic test is performed and a short summary of results interpretation. You can read the full transcript below. Optokinetic stimulation What we have…
Transcript How to operate the Interacoustics AS608 device. To turn on the AS608, ensure that the headsets are connected and that the AS608 is connected to a power source or has the batteries installe…
What is the short increment sensitivity index (SISI) test? The short increment sensitivity index (SISI) test measures the ability to recognise 1dB increases in intensity during a series of bursts of…
What is pure tone audiometry? Pure tone audiometry is a hearing test that establishes hearing sensitivity at various frequencies for air conduction and bone conduction. The test can specify the air c…
