After 1 week used, the panel does absorb some sounds but doesn't make a massive change. I download a decibel meter app for testing and it's showed the noise only decrease 1-2dB. (i guess a thick curtain may achieve the same effect). It just makes the noise softer, less sharp but can't fully block them. By the way, the panel doesn't match the description picture at all and there is a corner of the panel that was damaged during transportation. Overall the shopping experience is a thumbs down.
Hello Ying, we are sorry to hear your response. Here is a quote from one of the 4 or 5 five star responses we received over this weekend ...
'Went out of their way to do everything they could to make sure I got what I wanted!
Great product. Great value. Great service.'
We are disappointed firstly because we did the same for you over an extended period of consultation by emails (with your photos of the window etc) and phone discussion. What we supplied was a thicker blockout, with an extra foam layer to fill the larger window cavity - all at no extra cost, and as discussed, according to our understanding.
So we are sorry and surprised to hear accordingly, and further of a damaged corner during shipping, especially as the panels had 60mm of foam facing outwards on each side and we further overlaid them, backed together in padded foam wrap.
As far as your experience with the sound absorption, we also are surprised about this compared to other feedback we have received. A hard reflective material such as plywood added to the back of the panel in your case will assist further in reflecting the sound back to its source. SB
Great product. Doesnt maybe block out as much noise as I had hoped, but still very effective. Fast shipping and good customer service as well.
Thanks for bringing this to our attention, it's unfortunate that our product did not fully meet your expectations. Thanks for your honest and kind words. Joe
