Document Summary

Uncontrolled noise and lack of speech privacy negatively affect concentration, slowing task performance, increasing errors and threatening the continuity of creative thought. Acoustic problems also impact comfort, stress levels and morale. Running the partition slab to slab through the ceiling or raised floor provides the highest level of sound separation. Suspending a partition from the structural floor above down to the top of the ceiling grid is also effective(which is cheaper than a slab to slab wall) or. Suspending sheet lead from the structural floor above down to the ceiling. Using batt insulation within the stud cavity (absorption); or. Sound attenuation is achieved in a metal stud partition by: Partition strategies to help mitigate the transference of sound: = decibels unit of measure for the intensity sound. = hertz the pitch of the sound measured in number of cycles (vibrations) per second ability of a material of assembly to block sound the degree of sound absorption of a material.
