Editor's Perspective

January - February 2015

Editorial written by Stavros Hatzopoulos

January - February 2015

  First of all our best wishes for a fulfilling and "clinically creative" 2015 !!  There is a reason why I have highlighted the term "clinically" since the next few months our focus will be dedicated to updates in the area of OAE Hardware. There are several patterns emerging from the available OAE hardware as of today. (i) Screening applications have totally overshadowed OAE research and the majority of devices offer OAE tests in moderate frequency ranges rarely exceeding 6.0 kHz. Only a handful of devices offer DPOAE testing up-to 12 kHz. This is not a surprise since the area of "clinical...

October - January 2014: Also 2nd- and 3rd-order intervals of spontaneous otoacoustic emissions confirm theory of local tuned oscillators

Guest editorial Martin Braun, PhD : Neuroscience of Music, S-66492 Värmskog, Sweden

October - January 2014: Also 2nd- and 3rd-order intervals of spontaneous otoacoustic emissions confirm theory of local tuned oscillators

  Introduction Understanding the origin of spontaneous otoacoustic emissions (SOAEs) in mammals has been a challenge for more than three decades. Right from the beginning two mutually exclusive concepts were explored. After 30 years this has now resulted in two well established but incompatible theories, the global standing-wave theory and the local oscillator theory. The outcome of this controversy will be important for our understanding of inner ear functions, because local tuned oscillators in the cochlea would indicate the possibility of frequency analysis via local resonance also in mammals. In a recent investigation of this controversy, Braun (2013) gained new information from...

22/01/2015 : OAE Hardware vendor Updates

The updates in the area of OAE hardware have made us notice that we had to put more emphasis on the various hardware / software updates posted by the OAE and AEP vendors. Now you can find these communications in a special page , but you will notice that vendors do not communicate routinely outside their websites new information. For the last 8 years .. we were obtaining these "details" by contacting the regional sales managers. Unfortunately there is a global turn-over of positions and the same people rarely remain in the same post .. for more than 2-3 years...

15/01/2015: Otometrics Webimar series

The INTERNET is without a doubt the best channel to share information, thus the creation of the term webinar, meaning a on-line seminar. Otometrics , the known Danish audiology/ENT equipment manufacturer, advertises a series of webinars one of which is on pre-school hearing screening (March 16, 2015). For more information access the main Otometrics Webinar series page. In case you are interested in a past event , just register in the Otometrics site and you will get access to the recorded webinar event.

04/01/2015: 2014 Access Statistics

The Access statistics of 2014 are on-line earlier that expected , thanks to Google ... Several trends emerge with the most obvious the globalization of accesses in comparison to the numbers we had 4 years ago. The number of countries requesting information has also increased to 131 ... some have very few accesses to the Portal material ... but it is important to see that we move to an global INTERNET community. Some details which should be mentioned:   1. The "Americas" are monopolized mainly by accesses from the US and Canada (73.78%) 2. South America is monopolized by accesses from Brasil (68.77%). 3. Asia...

The  OAE Hardware pages were updated with the product line of Mimosa Acoustics including a portable DPOAE screener and a portable OAE system capable of TEOAE / DPOAE / SFOAE recordings. Both products are capable of recording middle ear reflectance, a state of the art approach to middle ear function assessment. In Early 2015 , we have programmed a revision of the OAE Hardware and OAE software pages  since a lot of the models which are theoretically available have been redrawn in 2014.

03/03/2014: Regarding FORUM posting

We have received a number of questions regarding "Freezing" actions on posts from various users. From January 01, 2014 we have established a new set of rules with the objective to protect the OAE Portal from spamming. In the past the FORUM addresses have been captured by various  INTERNET fishing programs and as a result many sections were saturated with advertisements and other irrelevant information. In order to block these actions we have introduced a small delay in the FORUM posting procedure. First, the sender has to be approved and then the argument he/she submits has to be evaluated and approved...

19/02/2014 : 2013 Portal Statistics

The data from Google Analytics are in,  regarding the OAE Portal activity in 2013. There is a light decrease of accesses per month (5300) probably due due to the fact that the sections with the powerpoint lectures and white paper were available in the old site , for which we don't have tracking statistics. The accesses from the Americas still display the highest ranking with 41.38% , followed by European accesses with 30.98% . There is a rather strong increase in the accesses from Asia (19.94 %), a number tripled over the last 2 years.  Comparison data can be found in...

From the Editor : My impressions from the last meetings I have attended in 2012/2013, is that OAE technology has arrived at a still point (plateau). I believe this is the direct consequence of using OAEs exclusively to -partially- screen infants (I am trying to be  a bit provocative here ...) . The OAE technology has not evolved in consumer terms,  despite considerable developments in signal processing, algorithm design, electronics etc. Border line changes arrive at the consumer .. mainly as a re-elaboration of previously developed OAE technologies . I have been asked many times .. What I would like to see...

New Rules of the Forum

The last two weeks we have noticed that we had had four cases of SPAM in the OAE Forum. The reasons for SPAM are beyond our understanding. With the initial FORUM setup it was impossible to create topics automatically (by spamming spiders, spamming robots etc) and we had tried to resolve the problems we had in the old Forum. A spamming message requires a manual insertion .. and despite this in 4 cases someone took time to insert spamming messages. The objectives can be multiple .. but we would like to stop here. We have established two NEW RULES for the...

The NEW Forum

  We have activated the structure of the NEW OAE Forum. For the moment this platform will contain information from October 2013 and on. We have also inserted a link to the OLD Forum (under the FORUM menu), to maintain access to old information, till September 2013. A word of caution about the OLD Forum, it is plagued by high level of SPAM.  We are also considering importing various messages from the OLD Forum to the New, but there is a lot to consider here specially of what can be considered important.
