Message: [QUOTE="RandomGuy, post: 2997654, member: 6422"] Well, on the bright side(pun intended) it looks like ETFE has up to a 70% absorption of acoustic noise... I'd definitely take it louder, than brighter. "Its acoustic properties can reduce excessive interior noise. No one notices acoustics done right, but when it’s wrong, it’s a problem for players, spectators and broadcasters. ETFE film has 70 percent acoustic absorption/transmittance, which dramatically reduces reverberations and creates more comfortable spaces. But it can also let exterior sounds – especially noise from rain falling on a roof – into the facility, so it’s important to carefully study the potential for both positive and negative acoustic effects when considering an ETFE system. Once the effects are understood, designers can take a number of different measures to “tune” the acoustics to mitigate unwanted noise." [/QUOTE]
