Re: Subject: Re: [Harp-L] soundproofing an interior room - another idea

[Vern <jevern@xxxxxxx>]

Carpet, drapery, cane-board, cork and other light, porous material is useful for suppressing sound reflections.  Since it is often visible in sound-controlled rooms, there is a common misconception that it blocks the passage of sound.

If my post has alerted possible buyers that any material lacking mass is likely to be ineffective, then I am content.  Caveat emptor.

Although I would be very surprised to learn that a hydroponic tent makes a dandy sound booth, I can't say for sure that it does not.  Beyond the above generalizations, I am not prepared to argue the effectiveness of any particular materials. My one first-hand experience was practicing guitar in a booth separated from a saxophone by two layers of 3/4" thick cane board. It sounded as if I were in the same booth with the sax.

Thank you for reminding me again that email makes a poor medium for levity.

As long as one adds a good thick base inside (carpeting?), and something on top (thick  batting, perhaps?), the sound could even be prevented from transmitting to the apartment (or room) above and below. The idea was to use      this as a starting base and with some ingenuity pad it out enough TO be used as an improvised sound booth (which run into the $5,000 and up range for anything close to this size).
