I have to suffer wall to wall carpeting in my present house, and the frequency response for the speakers in my sound system has to be attenuated for that. I once lived in an 1840 built house that had all hardwood floors, which had quite a different response to my hi-fi, and it was only ameliorated by area rugs in strategic positions.   I am quite sure that there are others on the list who can give chapter and verse on the physics of all this, - I can only tell you of my own experience. But the above is, to my way of thinking, certainly something to consider. There is also the consideration of curtains and furniture coverings, both of which will have some effect on the sound quality in a room.         Bob Conway <conwayb@post.queensu.ca> Organic DeeJay Emeritus CFRC-FM 101.9 MHz Radio Queen's University Kingston, Ontario, K7L 3N6 CANADA

In a home you are more likely to get "echo" or a slapping response, rather than reverberation because reverberation requires volume of air and distance for travel time in addition to hard surfaces. My preference is to use area rugs over hard floors, so that you have the option of livening or warming the acoustics in the room depending upon the activity. I have even seen churches where most satisfactory results have been obtained from using a decorative carpet in the altar area, chancel, or crossing. It sufficiently deadens the acoustics, controls noisy feet and yaking, but is easily removal not only for acoustical adjustment but for clearning. It doesn't matter how much time is spent vacuuming, a carper never get clean because of all the #$&*% which penetrates and winds up in permanent residence in the pad. When I lived in Vermont I had a ballroom on the third floor of the house with only my stereo equipemtn in it: plaster walls, hardwood floor, and it was glorious (about 45' x 25' with a barrel ceiling 6' at the walls and 10' at the peak; it was extremely warm and live, with about 1-1/2 to 2 seconds reberation--was great for plainson! Go for the area rugs;decor wise they look much more impressive than carpet (to me IMHO)   Bruce Cornely ============ o o o o ============== o o o ______________ o o o o o o ______________ o o o OHS ======================== AGO

Try with and without area rugs.....but I bet you will choose at least some padding be it rugs or in the furniture. When I was building a house organ (pipe) I found that the sound was better with the rugs than without. Empty room (hardwood, plaster) gave a sort of hard sound that was not pleasant to the ear. Different from reverb......RandyT

Hard reflective surfaces should give the best possible sound, and a good amount of finish voicing will take care of any harshness in the sound and the bass/mid/treble balance. IMHO, the best result will be for clarity and not over-loud voices (cleanliness in stead of brute force, if you will)   just my thoughts (since you asked)   Rick Maryman

What think ye? >   An interesting set of responses - I'm certainly surprised to note the feelings of some that some acoustic damping is desirable.That was certainly NOT my experience when I acquired a house organ about 8 years ago.At the time I worked on the basis of my observations of other house organs viz=20   - the successful ones were usually those whose owners had been able to provide adequate space - trying to cram an instrument into a small space was almost always unsatisfactory   - if the space was acoustically 'live' then the result was even better   In preparation for my house organ I simply provided as large a space as could be managed. The music room I built was always intended for 'live' acoustics - double cube dimensions, no carpets or drapes, polished wood floor. The result has been excellent - I've certainly not experienced any ugliness of sound or unwanted echo. The acoustic simply adds warmth to the organ sound (note of course that what you are seeking is the opposite of what is looked for in hi-fi systems where you do NOT wish to modify the sound).   You do need an instrument voiced with due moderation - extremes of voicing just don't work in a house environment. Of the professionally built house organs I've seen, 'skinny' neo baroque voicing seems to be the worst fault. You also need to address the issue of how to ensure that the organ is not to hard on the players ears (another very common fault). But with those issues properly addressed I would always go for as little in the way of rugs, carpets, curtains etc. as possible   Those interested may care to look at my web page where you can see in more detail what I did and read some (possibly coherent) further notes on the issues I saw as important.     Regards       Roger         Roger Brown robrown@ozemail.com.au http://www.ozemail.com.au/~robrown/

Nice to see nothing's changed on PipeChat, that you're all still piping up and being heard! :)   I'm still catching up on my PipeChat reading, but the Wanamaker's question caught my eye.
