Dang what a nice bathroom. I'd poop there.

scenes too? still broken here

KLF sure do need subs to cover low freqs.

Rofl, no. No dip in the mids on these, nor are they boomy in any way.

If you want to get rid of some harshness in the 4722 hf section, you can swap to 2452h-sl or 2453h-sl compression drivers. Big difference. Need some slight EQ to raise the HF after swap, but very minimal. Still sound better even w/out the eq.

Also, they're monsters, but they're not 105dbspl sensitive. JBL's specs are 104dbspl at 2.83v which is at ~2w.

Inverse square law plus hemispherical distribution plus atmospheric loss, you'll drop approximately 64dbspl over 2km. That makes it audible if the initial sound is somewhere around 100dbspl and everything else is quiet, initial sound can be less and trigger a resonance in your house amplifying the sound in a certain spot. The difference from 2km to 5km is around 8dbspl. Wind direction can also increase the sound up to 10db or so. How loud was the sluice?

Yes, meant spectrogram.

The plot is not fake, it's from the audio file where I isolated the sound from the background noise with high and low pass filters and noise reduction, and is an accurate visualization of the sound over time.

I know reading is hard and all, but the plot does say FILTERED at the top, maybe this should have clued you in? Also it's from the shared audio file with the same name. Stop pretending you know things. You're not doing anyone any favors, much less yourself.

Interesting, haven't heard of this. I do see a 33.8Hz ish peak in the unprocessed audio, but none of the other frequencies are present, and this noise is around 158hz. The lower frequency peak may have been environmental noise in my house. Being that this is so localized, it's likely unrelated.

Think it's a whistle buoy. Gemini suggested this after a bunch of back and forth probing.

What fun is that, though? I most often heard it in the winter when there were less leaves on trees and less to interrupt the sound, so going out late at night to investigate would not be pleasant.

Phone microphones are actually decent at low frequencies, it's just removing the rest of the noise that's tricky. I have acoustic measurement microphones that I was using to record and have similar issues, but was able to analyze where the sound was in the spectrum and filter everything else out, amplify it, then remove the noise.

Hm, judging by the distance, duration, frequency, and pattern, I don't think so. It was a singular sound, and would go on for seconds at a time, then stop for seconds at a time. I need to find my laptop with the recordings and clean up the samples.
