What's the best bass trap material?
It should be safe to install in my bedroom.
Thanks

Something weird about that article. According to the author "Theory says that the deeper an absorber is, the lower a frequency it will absorb. It’s called the quarter wavelength effect and it definitely holds true."
What about the waterfall graph? That looks interesting.Something weird about that article. According to the author "Theory says that the deeper an absorber is, the lower a frequency it will absorb. It’s called the quarter wavelength effect and it definitely holds true."
Googling "quarter wavelength effect" says: "...the thickness of the sound absorbing material should be a quarter-wavelength of the lowest frequency of interest." So if you multiply the thickness of the material by 4, you'll find the wavelength of the lowest frequency it can absorb.
The author used 6-inch material, which is the quarter wavelength of 565Hz, which should be the lowest frequency it can absorb. But he claims it absorbs down to 35Hz, which has a quarter wavelength of 8 feet. I guess his comment about the quarter wavelength effect "definitely holds true" should be taken with a grain of salt.
What's interesting is that there is no "before" measurement; only the "after" measurement was posted in the article. So there's no way to know how much of the "after" graph is a result of the bass trap.What about the waterfall graph? That looks interesting.
