Description of the observing site
Location of the observing site: general description
Backyard - yard blasted into the side of a hill (Phoenix, AZ)

Describe in detail the meteorological conditions at your observing site
(temperature, humidity, wind, rain, clouds, etc...):-42F, no wind,
clear to partly cloudy, 20% humidity

Describe in detail your observing site (vegetation, buildings,fences,
and -especially- any metal objects in your vicinity, etc...):
In backyard (sunken) in between 2-storey house & 15ft concrete high back
topped with 3 ft iron fence. I was standing next to my DV Camcorder that was
on a 5ft aluminum latter.

Describe in detail your outlook and clothing during observation
#11-01# (especially important is your haircut,glasses and metal objects):
Short haircut; no glasses; with cotton

Specify all electrical equipment at the observing site
#12-01# and in its vicinity:
DV camcorder & a am/fm radio that was powered on about 30-40ft away

Details about the sound from the meteor
Specify the date and time of your sound observation: month
11

Specify the date and time of your sound observation: day
18

Specify the date and time of your sound observation: year
2001

Specify the date and time of your sound observation: local time(hh:mm:ss.ss)
02:00:00.00

How would you describe the sound you heard?
I've heard sonic booms & this was very similar (boom/popping) but preceeded
by a strange short hissing or bass-like fizzle.

How long did the sound last (seconds)?
1.5-2.5

Which direction did the sound come from
(the meteor, the ground, some object, air, all directions)?
behind me (hissing; same direction as flash); all sides (boom)
How many observers from your vicinity heard a sound from that meteor,
and how many observers did not hear it?
observers heard sound: 1

observers did not hear sound:

Did you see the meteor that could be connected with the sound?
1=yes, simultaneously with the sound
2=yes, a moment before the sound
3=yes, a moment after the sound
4=I can not decide which meteor was connected to the sound
0=no
4
If YES, what was the correlation with the light maximum?
0=I can not decide
1=the sound appeared SIMULTANEOUSLY with the light maximum
2=the sound appeared BEFORE the light maximum
3=the sound appeared AFTER the light maximum
3
Did you notice any other unusual phenomena which might be related to
the meteor (electric or magnetic effects, strange odors, unusual
animal behavior, strange air glow, etc...)?
I think I noticed a flash behind me before the noise.

Additional remarks
#30-01# Additional remarks related to this event:
I was filming the shower for a friend & business associate you may have heard
of Steve Kates (Dr. Sky). A few hours into the filming, I saw a group of
meteors (1 with dissipating trail) followed a short time later by a strange
noise. I did get this noise digitally recorded on my DV Camcorder.
Furthermore, at a different time however, Steve had a similar experience
while doing a live worldwide radio broadcast in which he commented on it very
briefly live on the show. However, no good audio is available from that event.
I have not yet tried to digitally isolate the noise from the background noise
I heard from the waterfall. This background noise seems to have drowned out
the hissing noise but definately not the boom. (wav file attached)
