Hi All,
I came across this rather interesting spreadsheet while googling for inform=
ation on typical sound levels in Olympic National Park.
http://www.e-a-r.com/pdf/hearingcons/Noise_Nav.xls
According to the spiel:
"...the Noise Navigator spreadsheet of sound levels for more than 1700 occu=
pational, recreational, and military noise sources. The data are compiled =
from references in the literature and from our own measurements. For each =
source the reference is listed, and as available additional notes are provi=
ded. When the primary reference cites sources for its data, those too are =
listed.
The tabled values are primarily A-weighted sound levels, as opposed to time=
-weighted average levels or Leqs."
A couple of examples of entries:
Haleakala volcano (Maui), in crater, no wind - 5dBA
Leaf falling onto fern fronds, single big maple leaf, Hoh Valley
(distance=
1.8m) - 30dBA
cheers
Paul
