The following link is to an excellent article by Neil Bauman, Ph.D concerning the different applications that hearing/induction loop systems and Bluetooth are design to address.
It covers most of the issues with using Bluetooth in large area public environments such as hearing aid battery drain, area coverage and pairing with multiple devices.
What I find most interesting is that he writes about the perception of Telecoils in hearing aids being ‘updated technology’ that is being phased out – and why it simply isn’t the case, in fact it’s quite the opposite.
Check it out, it well worth 5 minutes.
