Why Is A Home Theatre System Marketed As A 5.1 System Rather Than A 6 System Even Though There Are 6 Loudspeakers?
While this is not necessarily a question that an audiologist may ask, it summarizes much about room acoustics and speech acoustics.

Is There Evidence for Screening for Vertebral Artery Insufficiency Before Maneuvers That Requires Neck Manipulation Such As The Epley Maneuver?
Research has been conducted to determine the validity of the Vertebral Artery Screening Test (VAST). As with any screening, we would be interested in its sensitivity and specificity.
Is Someone with a Hearing Loss More (or Less) Susceptible to Future Hearing Deterioration from Loud Than Those with Normal Hearing?
One’s initial gut feeling is that if there is already cochlear damage, then this would increase the chances of further hearing difficulty when compared with someone with normal cochlear function, given the same noise exposure. And shouldn’t that person therefore be counselled to double up on their efforts to wear hearing protection?
Why Can Normal Hearing People Hear Better In Very Noisy Places With Earplugs?
Many of us have experienced going to a concert and listening to the music from the tenth row back. Even if you know the words to the songs, it can be difficult to hear them. However, if we were to use hearing protection (such as Musicians’ earplugs), the words are much more intelligible.
Should I Apply An Air-Bone Gap Correction As Default When Fitting Air Conduction Hearing Aids?
Applying corrections for Air-Bone-Gap (ABG) when fitting air-conduction hearing aids is included in many generic and proprietary fitting prescriptions. Because prescription hearing aids are fit and verified via PC software modules, the choice of whether to apply ABG corrections is usually a default setting that may be somewhat hidden and, as a result, not often changed.
An Advantage of Bone Conduction Devices Is That There Will Not Be Feedback—True or False?
Bone-conduction hearing devices connected to skin-penetrating abutments (e.g., Oticon Medical Ponto, Cochlear BAHA) can certainly generate feedback. As expected, feedback becomes increasingly concerning with worsening degrees of cochlear hearing loss. However, the mechanisms contributing to feedback in bone-conduction hearing devices differ slightly from those in air-conduction hearing aids.
Why Is It Crucial To Measure Bone Conduction Hearing Thresholds Directly with the User’s Specific Device and Connection In Place?
Measuring bone conduction hearing thresholds in-situ with the device and connection that the user is wearing is critical for several key reasons, particularly when it comes to the prescription of amplification targets and ensuring that the hearing aid is properly calibrated to meet the user’s specific needs.
When you do REM on a CROS or BiCROS do you measure both ears, or just the better ear? My mom wears BiCROS and we are seeing her audiologist tomorrow.
There is nothing to measure for REMs in the bad ear; there’s no output there! It’s all going to the better ear.
My Patient Has An Open Vent In Their Earmold and I Plan To Measure Their Earmold RECD and Then Fit the Hearing Aid In the Test Box. Should I Leave The Vent Open?
Probably not. When you put the earmold on for the RECD, the sound will be entering the ear through the earmold tubing. Some will leak out through the vent, but no test signal will come in. That means the RECD only captures one of the two vent paths.
If You are Performing an Insertion Gain Measurement, Do You Need to Subtract the REUR If It’s a Non-occluding Fitting?
Non-occluding fittings present unique challenges and considerations when conducting real-ear measurements (REM). For clinicians who subscribe to the insertion gain method for verifying devices to prescriptive targets, confusion can arise regarding how to properly account for the real-ear unaided response (REUR) or real-ear unaided gain (REUG), given it is typically not impacted with open fittings.
