In this document http://www.archive.org/details/sancesde ... 03physgoog the famous French organ builder Cavaillé-Coll claims he can reduce the reverberation of a room with many threads of wool or cotton across the room. The document is Séances de la Société française de physique, 1877, in French.
The article is reduced to pp 24-25 of the pdf. If you do not want to download the pdf you can view the Full Text version and search "fils de laine".
Has anybody more scientific information? (required length, diameter of the threads, thread direction etc.) Is anybody aware of a paper by Robert S. Gregg? Reducing some rooms' reverberation would be useful both for music and for other situations Cavaillé-Coll was proud because the process is cheap and easy.
