Last week Apple filed a detailed patent application relating to a new iPhone audio-sharing network concept. While the filing touches on hearing aid technology, it is by no means limited to that narrow definition. Another application applies to teleconferencing, for example. In fact, one of the benefits of this technology relates to a "conference telephone." The technology is designed to cut out background murmurs and general noise while executives discuss business with distant colleagues and/or potential clients. At the end of the day, the patent relates to both students and the enterprise. Yes, the Devil is in the details.
