Project Silent Hills

Post by admin » Sat Oct 19, 2019 9:12 pm

The MABRC and APES groups conducted experiments to see if the distance of wood knocks and vocalizations varied under different conditions and at what distances they could be heard from. What the data showed afterwards, along with the personal experiences of those who participated, it opened their eyes to some dramatic results.

The experiment was conducted in three phases.

Here is the data of Phase 1, conducted during a Memorial Day Expedition.

Phase 2 was conducted during Winter Conditions to see if the lack of vegetation on the trees and the temperature had any affect on the distance that the wood knocks and vocalizations could be heard.

PHASE 2 - Silent Hills Project

I still have to add it to the other information, but here is the data for what we call Phase 2 of the project, how cold weather affects the decibel readings.

I have to say this first off, on Friday night about 7 PM, we heard a vocalization off in the distance, it was clear but what we thought was at a distance of a half mile or more from the camp.

Date: Jan. 16, 2016
Location: Malfunction Junction (Natural Dam, Arkansas)
Temperature: 38 degrees F.
Participants: CompresserMike, Squatchfinder, Sawdustt, Cherokee Rose, Darkwing

Call Blast 32 32 38
Vocalization 35 31 30

0 means that it did not clear over the ambient noise levels, the only reason the listening team heard the knocks was because they anticipated them and was listening intently for them.

0 means that it did not clear over the ambient noise levels, the only reason the listening team heard the knocks was because they anticipated them and was listening intently for them.

On the Memorial Day expedition, the call blasting was heard at Base Camp during the experiment. Road distance is 7/10 miles, while by direct distance it's 6/10 miles.

To test the distance it could be heard during colder weather, Cherokee Rose and Darkwing returned to Base Camp and listened for several minutes before Darkwing started traveling back towards the experiment Base site. At the 3/10 mile mark, Darkwing was finally able to hear the call blasting.

From what was observed from the experiment in Phase 2, the cold adversely affects the distance that the wood knocks and vocalizations can travel. Leading the field team to deduce that the vocalization heard the night before was even closer than originally thought. The cold actually halved the distance on all knocks and vocals.

Phase 3 will now be planned out, in it, we will be seeing what the distance decibel ranges are using parabolics and recorders of various types and makes. To see the difference in each according to sound.

Phase 3 was conducted to see how well recorders and parabolics could pick up the wood knocks and vocalizations.

Phase 3 - Utilizing parabolics and recorders to see how the sound is affected at the distances.
Below is the readings taken with the decibel reader. We are still evaluating the audio recorded by the parabolics and will post that soon.
