Talk:Outdoor-Indoor Transmission Class

From Wikipedia, the free encyclopedia

This reads like a dictionary entry not a Wikipedia article. Brian 17:45, 2 July 2006 (UTC)btball

[edit] I stand corrected

A sysop has determined that it is not CSD ... so I bow to great experience and wisdom. But it does still read as a dictionary entry (IMHO) and would benefit by expansion and links from other articles (at the moment it is linkless). Brian 18:28, 2 July 2006 (UTC)btball

[edit] On using OITC for home remodeling

From an email message I sent to an Architecture web-site in April, 2008:

- - My wife and I live on a busy road in..... Lots of traffic noise. We would like to install a new entry door on our home with suitable OITC ratings, but we don't know what the acceptable range would be, or how to estimate the OITC of our present door.

- - Response: We usually do not get involved with acoustical consulting for homeowners, but initially you need to determine what the overall sound level (dBA) is outside and inside your house. You can do this with a cheap sound level meter from Radio Shack. The nationally recognized interior sound level should not exceed 45 dBA. If the level outside is 75 dBA, then you would need an OITC 30 door in order to reduce the level inside down to 45 dBA. But you also need to look at the windows and exterior walls to see if they also meet an OITC of 30. Sound will take the path of least resistance, so if the door is an OITC 30 and the windows are only an OITC of 23, then most of the sound will bypass the door and come in through the windows

I asked the gentleman if it was all right to post his reply, and he agreed, with the proviso that I should not identify him in any way which would lead to his receiving lots of email on this topic. He is in a supervisory position related to Acoustical Testing. (Babybowen (talk) 09:00, 2 May 2008 (UTC))
