Please note that the audio might be loud or a bit distorted, this is due to the siren being mounted low close to the ground and the recorder being about 20 or so feet away from the siren.
This audio was captured from Froomfield, Sarnia, ON after the Sarnia sirens have been tested.

Interesting day, my friend invited me to come with him to do some shopping in Niagara Region so I thought to myself why dont I try to attempt Youngstown's noon whistle? so I went there for 15 minutes before noon or so and walked the trail to a bench and setup shop and 11:57 AM or so came around and in the distance I hear the nice sounding 8/16 Port Sterling wind up. I originally wanted to come here when they do Thursday night fire siren testing for the whole County but I guess they stopped doing that.
Note: the unit I was at on Coronation Drive stopped working during the whoop signal for some reason, but it fully worked for the alert signal. During the alert signal, both sirens produced a dual-tone-like sound because the other Whelen has a higher-pitched tone. Both sirens are tested in a 2-minute whoop signal, followed by a 5-minute silence, and then a 1-minute alert for an all-clear signal. I reduced the waiting time for the 5-minute silence so it will go on to the alert signal instead of waiting the full 5 minutes on the audio recording.
Note:
This siren's rotator was broken, so the siren was facing the audio recorder the whole time so you could hear it pretty well during the test.
Note:
Due to settings on the audio recorder, the wind-down sound may fade in and out, this was later fixed by setting the mic sensitivity to high instead of auto.
