Ann: Becoming a substantial holder, page-17

I read that too, but scope of the announcement was quite narrow. There certainly are other studies involving the recording and analysis of respiratory sounds:

These studies all involved the capture and analysis of respiratory sounds in one context or another. I haven't yet read through them in detail or followed up in the media, published articles, or the companies doing the studies (I have a day job, a night family, and interests) but there may be something useful in these experiences that we haven't thought of.
