[Uni-verse] Acoustic Material Database

[Lauri Savioja]

Hi Emil,

Excellent!

The reason for duplicates is that I removed some columns from the
xls-file. They contained more detailed information of the material
such as thicknes or how it was fixed in the wall and if there was air
gap between the absorbent and the wall, and so on, ...

Ludde, do you have any proposal how we should proceed ?

Regards,
	Lauri
