Don’t newer connective technologies work better?
New wireless technologies, including Wi-Fi and Bluetooth, enable binaural phone and stereo TV listening. Such technologies, while helpful in sports bars and exercise venues, are not, as yet, a viable for assistive listening. Some years in the future, Bluetooth Low Energy holds promise. But for the present Bluetooth requires significant battery power and is a private phone-to-hearing aid connection. Wi-Fi entails audio delay that negatively impacts speech intelligibility and music enjoyment. An alternative future assistive listening solution—one that, like hearing loops, is hearing aid compatible—will need similarly to:
be inexpensive (essentially no cost to the consumer),
be capable of covering a wide area,
drain little battery power (telecoils require no power),
be universally accessible worldwide,
be sufficiently miniaturized to fit in nearly all hearing aids and
transmit the audio signal without audible latency.
