I thought it might be a resonant cousin of waterhammer, but attempts to detune it with water-hammer suppressors had zero effect. The whole-house pressure regulator proved to be the source. I’m sure plumbing drain vents can work like a Incan pan flute, but I’d expect a deep bass note. The pressure regulator was making a fixed mid-tone pitch, in the middle C-ish range, though I didn’t measure it.

That sounds like a resonant air column to me…beautiful
