I just got this app that detects infrasound and I suspected it for some time but not finding the right app. It recording big signal at 20 hertz and below infrasound. In downtown Vancouver alarms going off like crazy. I wish I could show you but I do not see any attachments to this comments. Should I be worry that some event is going on now. New to this and big room for error but this is what I recording

In reply to C. Bremner. I would believe that a modern subwoofer is able to produce this kind of infrasound, but not idea were to verify that.

We’ve just been through two days and nights of a techno-pop concert (heavy on the bass) at a local exhibition ground that was heard and felt more than 5 kilometres east in a straight line. My neighbours and I are not happy, and I wonder if the promoter is using some kind of bass speaker that produces ELF sound. My home is 2 kilometres from the venue, and I could hear/feel the bass line in a small windowless bathroom. Can someone point me towards data that could confirm this speculation, please?

[…] Horror movie soundtracks sometimes include infrasound, which is sound below the range of human hearing. Even though we can’t hear it we can still feel it and infrasound has been shown to induce anxiety, heart palpitations, and shivering..
