John Heisz - Speakers and Audio Projects | Acoustic Panels from the Future? and the Haas Effect @IBuildIt | Uploaded 1 year ago | Updated 10 hours ago
Rather than using drywall to finish the walls in a room, one could make cloth wrapped acoustic panels that fill the space and extend from floor to ceiling! And it could be reversible, with a different colour fabric on the other side! That's it, I'm doing it!!
While the Haas effect points out something important about how our hearing works, it doesn't address what happens when two sounds converge at a single point at different times. Comb filtering (a series of peaks and dips in the response) occurs and has a detrimental impact on the original single.
It reduces clarity because you have a disrupted response. Also, instead of just one strong signal, you have two with one reaching your ear slightly behind the direct sound. While this does give spacial cues that add dimension to the listening space, it also smears the sound that reaches your ear. There's a reason why they say to wear headphones when you need to listen to something carefully, since headphones are as close as you can get to reflection-free listening.
Using the findings of this effect to claim that reflections are good and needed for proper stereo imaging ignores or minimizes the comb filtering that reflections cause.
