Hungaropan® SonOr: An enhanced airborne glass structure. Rw: Values higher than 33 dB.

If the sound absorption value is subtracted from the noise level in the given environment. then the table can be used to determine what the sound insulation actually means. For example: traffic street noise level 60 dB, window glazing with Hungaropan® SonOr 42, which means 42 dB airborne noise: 60- 42 = 18 dB is a filtered noise level ideally in the "very low" range from the above table. Of course, glazing is just one of the factors, insulation of the wall, and the right frame structure is equally important for noise suppression.
