Maybe you've heard of "Fake News"? The same happens in the world of acoustics! Here's a place for discussing acoustic myths, legends, mysteries, "questionable" treatment, scams, hoaxes, and just plain old bad information about acoustics, sound, and audio.

More Springy Thingies...

Speaking of strange spring-loaded acoustic stuff, here's another "springy thingy" that I've had in my file of "weird acoustic stuff", for a while, and been meaning to post...

Yup. A bass trap with springs in it, that do ... something! :)

It is called: "A low-frequency bass trap with Pistonic/Helmholtz action"

Here's more info on that... https://www.msr-inc.com/downloads/pdf_f ... ntary3.pdf

Once again, I'd love to see some real test results from a real independent lab! It would be fascinating to find out what that thing actually does...

A couple of possibilities:

1. IF the trash can is part of the assembly, it would act as a resonator (the plastic bag is the adjustable damping).

2. It's the new Hexatheremin.

Great idea! Here's your chance to make a killing on the snake-oil acosutic treatment market: re-purpose trash cans as acosutic treatment! Don't call it a "bass trap", call it a "bass dump", or some such! I bet you could sell those things for a pretty penny...
