We’ll be live blogging from the upcoming Conference on the Diagnosis and Management of Auditory Neuropathy Spectrum Disorders (ANSD), hosted by USF Professor Charles Berlin and Vanderbilt Professor Linda Hood, this Thursday through Saturday March 15th through 17th at All Children’s [sic] Hospital in St Petersburg, Florida.
Topics covered include:
• Results and Outcomes from more than 500 ANSD Patients
• Hearing Aids vs. Cochlear Implants
• Cortical Evoked Potentials
• Newest Developments in Trans-Tympanic ECochG
• Speech Language Management
You can follow developments on Twitter by using the #ANSD hashtag & by following @ANSD2012
On the docket are the following sessions: Just click the links below for the separate blog entries, as they become available…

• Hands-on Practice Session in Otoacoustic Emissions (OAE) and Auditory Brainstem Response (ABR) Testing, by Kathy Slifer AuD
[We're looking forward to this one, and will have pictures.]

• Hearing Aids, vs. Monaural vs. Binaural Cochlear Implantation Results in Speech and Language Acquisition, by Susan Spirakis AuD
[We're looking forward to this one too, and will have questions regarding differing findings from Mike Dorman & his bimodal studies.]
• Little Patient, Big Doctor: My Journey and Experiences with Big Doctors vs Children as Patients, by Haleh Rabizadeh-Resnick JD
[Haleh was the subject of the controversial report Don't let a doctor destroy your baby's hearing on CNN]


Although they have differences, the Bellman Audio Domino Classic costs $200 less, and performs as well as the Comfort Contego. While the Contego has a zoom mic, the Audio Domino Classic has a tone control on the receiver, and also when stereo is input into the transmitter jack, the system switches to digital stereo (more on this in a moment).
Previously, A.U. raised a point about the 40ms latency of the Audio Domino vs 10ms delay in the Contego (vs. no latency with analog!) and how it can interfere with lipreading cues. [Note:In googling Comfort Contego specifications there is no mention of latency.] From personal experience, I haven’t noticed any latency issues; but more importantly, if either system is used with a TV, it is important to note that with the shift from NTSC to HDTV the lead/lag for the separate AC3 and MPEG audio streams can be up to 150mSec (and in practice is often much higher), so the (supposed) 30ms delta between the two doesn’t seem to be a factor.
Now, let’s say your patient wants a zoom mic on the transmitter & receiver: With the Contego, the user has to walk over and manually switch the transmitter. But, remember when I said above that the Bellman Audio Domino Classic transmits in digital stereo? Well, so does the Audio Domino Pro… But also, the Pro version does something Really Clever: The audio from the omni mic rides on the left channel simultaneously with the audio from the zoom mic! This way, the user need only push the button on the receiver to “zoom” the transmitter, saving endless user fiddling.
My friend Sarah, who blogs on her Speak Up Librarian website received upon my recommendation the Audio Domino Pro from her employer to use at work. She wrote two extensive first-person reviews here and here that are worth reading.
Finally, I welcome everyone’s own observations of FM ALD’s, whether good or bad; clinician or user, on The Hearing Blog’s article covering all things FM.
