Both are equally valid approaches to hearing aid verification, and historically are associated with the philosophies of prescribing gain according to the well-known NAL (REIG) and DSL (REAR) prescrip…
What sensation level is the speech presented at for the word recognition score in IA-AMTAS? In IA-AMTAS the clinician has the option to set the sensation level of the word recognition test. You can b…
Can dB (A) and dB (HL) be used interchangeably in sound field audiometry? Well, I’m not really sure they’re used “interchangeably” as such. Either one or the other scale would typically be used. In t…
Can dB (A) and dB (HL) be used interchangeably in sound field audiometry? Well, I’m not really sure they’re used “interchangeably” as such. Either one or the other scale would typically be used. In t…
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…
The term ‘in-situ’ in the context of audiology is often used to refer to when a hearing instrument or other device is being worn. What is in-situ SPL? In-situ SPL refers to the characteristics of a s…
I’ve noticed a consistent air bone gap at 4000 Hz during audiometry. Can you explain why this happens? For a complete answer to this issue the reader is strongly urged to read Margolis et al. (2013)…
Answer: This is a fascinating question which has occupied the audiological community for some time now, because in theory both techniques arise from the same neural generators but in practice there h…
As the name suggests the CE-Chirp® family is not a single stimulus but instead a family of short duration acoustic stimuli which can be used in evoked potential testing. They were designed with the o…
These numbers represent the number of cycles in a puretone burst sound signal commonly used in Auditory Brainstem Response (ABR) testing for hearing threshold estimation. The ABR relies upon an abrup…
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…
