For a recently-constructed school, are sound level measurements permissible in lieu of calculations? I recall that this was a path in LEED for Schools 2007.

hi, We are using LEED for Schools 2007 and am looking for some information on where to find STC ratings for ceiling and floor materials.

We have tectum panels (acoustic/insulation panels) above our beams. Do we have to add additional panels to the wall to make up for the ceiling area occupied by the exposed ceiling structure/beams?

The LEED v3 Reference book provides a table of "common materials". The LEED Online template asks for supporting documentation for all the materials used as an acoustic material finish.

The ANSI norm S12.60-2002 refers to IEC 61672-1 in order to define the A-weighted sound level. Is it allowed to use values from local code based on an acustic map of the city?

We are finishing up reporting on a school addition, and I have a few questions about the template. We are using the "calculation" option for both reverberation time and stc.

The school I am documenting has a Music Classroom that is mostly composed of ACT which meets the required NRC of .7, however, some of the ACT tiles have been replaced by Pyramid Sound Diffusers wit

Hello, We are working on filling out the Sound Absorption coefficient data in Table IEQp3-3.

Hi All, I newbie question: when the credit asks me to upload Form IEQp3-8, is this a form that I download somewhere and fill out, or is it just a document (or several documents) that I create myse
