STL-10?

Sounds like the Silent Hill siren

Yep, that's an STL-10 by the sound of it. The Doppler effect makes it sound creepy. I don't think I've ever heard one of those used for fire calls.

Ye betcha...and a beautiful sound she makes too with the audio waves bouncing off things and dancing in the humid nighttime atmosphere.

Dont think i've heard one of those before - very creepy! Thanks!

There used to be one in the hamlet jut south of where I live. One of the reasons why it sounded so close for being a bit over a mile away was that they decided to install it at ground level.

Imagine waking up to that in the middle of the night during a tornado warning...

Imagine the increased range of the 2001 if it had it's ports reduced to seven. The STL-10 was the most effective omnidirectional siren Federal ever made.

Which induces me with a random thought: does anybody on the siren board own a 2001 (of any kind). (preferably someone who could "experiment with it")

I just listened to a clip of the Silent Hill siren on YouTube, and it does sound very similar to that STL-10, especially with the Doppler effect. The sound for the Silent Hill siren was probably an E-57, which sounds almost exactly like an STL-10, with added studio effects. I've never seen the movie, but that's something I might do next Sunday...

The E-57 has a lighter rotor and has a faster acceleration/deceleration rate than the ponderous STL-10, but they both sound close to the same frequency at top speed.
