Hi there, Just bought brand new acoustic panels. These are 60cm x 120cm with rigid panel of polyurethane foam 40kg/m3 as the absorvent material. They are covered with good breathable fabric at both front and back sides. Images attached. I put them on my bedroom studio and they absorb quite nicely for my needs which is electronic music. The problem is that after 10 or 15 min my nose and skin started to scratch, I'm also having breathing issues, my chest kind of hurts and started to have nausea and stomach irritation. The whole reason why I bought these ones is because I wanted to avoid fiber glass and rockwool since I don't like the idea of sleeping with such material regardless how well covered it is. Now I'm kind of confused and I don't know what the heck is going on. My understanding is that my house already has some sort of polyurethane, like in my cushion, bed, pillows, etc so it cannot be that. Or can it? Could it be the wood with what has been made? I read that some type of wood dust is also toxic depending the sensitivity of people. Anyone has any experience or feedback? I hope I'm providing enough info if not kindly let me know. I could perhaps provide some additional pictures later. Thanks in advance for all your help.
