Recently I received a letter (in Danish mind you) from an experienced cochlear implant user who describes her personal experience with Cochlear’s new Loop Booster accessory. Thanks to Google Translate and Janni, the writer of the letter, I was able to translate it so that English speaking CI users can read about her Loop Booster experience.

Full disclosure: Janni Glæsner is the past president of the Danish Adult Cochlear Implant Association CIF http://cochlearimplant.dk/ and is currently is employed by Danaflex, the Danish distributor of Cochlear Products.

Johannes Kirke

The Johannes Church in Greve, DK offers a hearing loop for hearing device users. Like nearly all churches in Scandinavia

 

And the Noise Disappeared…

I don’t have to use a hearing loop often with my cochlear implant processors, but recently I was a confirmation at the Johannes Church in Greve Denmark and needed to turn on my telecoil to follow the sermon. I heard what I nearly always hear when I turn the telecoils my Cochlear CP810 processor on: a hum and crackling and my head orientation affects the loop signal strength.  Now, this noise doesn’t really bother me as it will not drown out the speech I want to hear. The crackle is just there, like the humming of a heating system or a fan. So if I think the sound is a bit too far away and requires me to pay very close attention to hear, such as at a lecture,  I use the telecoil, where possible.

A few weeks ago I learned of a new product from Cochlear called a Loop Booster. The Loop Booster is externally mounted on my Cochlear Implant device replacing the internal telecoil in the processor. The Loop Booster is larger and is said to improve the reception of sound through an induction loop system. Well, this aroused my curiosity!  Could a Loop Booster, I wondered, dampen – or perhaps even eliminate the hum and crackling I hear when using a  loop system? It was time for another visit to Johannes Church. So last Sunday I made the trek back to church to attend the All Saints Service.

I found a place discreetly on one of the back rows and settled in with a hymnal, my implant’s remote control and two Loop Boosters. Let the experiment begin!

My first thought turned to the loop system itself. Would it be turned on for the service? It sure was. But, as soon as I turned my processors’ telecoils on, the familiar hum and crackling appeared and when I moved my head the voice of the minister faded and the hum became even worse. It was time to attach the Loop Boosters on both processors. What happened next was amazing: The humming and crackling noise disappeared … and the sound was louder and clearer. It was as if an audio cable was connected from the microphone in the church to my processors. And when I moved my head, the signal did not disappear like it did when I used the built in telecoils. I also did not need to fine-tune using my remote control like I had to in the past.  The sound was clear and bright, just like I like! Wow!

Because I have heard that other CI users have problems with noise when they use the processor’s telecoils I am sharing this experience with you, and am curious as to whether the Loop Booster works for others.

PS: Readers of this blog may want to know that Janni lives in Denmark where, fortunately for all telecoil equipped hearing aids and all cochlear implants users, hearing loops are common place.  She uses Cochlear Model 5 CP810’s in both ears, but told me that the Loop Booster can also be used for the Nucleus Model 6 CP 910 processors. Janni and I would love to hear from other users of the Loop Booster. Janni can be reached via her Facebook page www.facebook.com/janni.glaesner?fref=ts and I can be reached at jsterkens@new.rr.com

Kudos to Cochlear for listening to its customers.
A few years back, many cochlear implant users complained that the older Freedom processors with their vertically positioned telecoils had better hearing loop reception than the newer Nucleus devices whose telecoils were mounted horizontally. It is nice to know the company took these complaints seriously and developed this new telecoil attachment. Telecoils can dramatically enhance the cochlear implant user’s hearing experience in public venues that offer hearing loops as shown in a recently published study in the October 2014 Hearing Review
