Sound Isolation Assembly

Sound Isolation Assembly

Calculation of STC, MTC, OITC and Rw explained
“Note: This document is an extension/adaptation of a document explaining STC and OITC It is expanded (+ additional adjustments and more in-depth comments) with the MTC and RW single number rating.”

Acoustic Shaping
“In the preceding sections we showed that significant forces could be generated in unsteady fields, especially standing wave fields, due to interaction between the field and solid (or liquid) particles.”

A Simple model of the sound insulation of gypsum board on resilient supports
“Although it is often standard procedure to use resilient channels to improve the sound transmission loss of a wall or floor system, there was no simple model of their performance…”

Are my speakers in a null?
I think my speakers are in a null. Briefly, the room is 11ft.8in. wide, 16ft. 4in. deep, with a ceiling of 8ft.

Bob Golds Room Mode Calculator
“For the case of a typical small studio…calculation shows that no frequency is likely to become prominent unless it (has) a high early intensity and a long decay. This condition* is satisfied only by the axial modes, which are therefore the only ones likely to become individually significant.”

IR818 – Measurements of sound insulation in building facades
“This report provides the results of over 100 laboratory measurements of the sound transmission loss of building fa├žade components. These included various wall and roof constructions along with some windows and a number of tests to evaluate the effects of vents on sound insulation. “

STC rating for glass – Sound Solutions
“The STC rating (acoustical properties) of glass are of considerable importance in many applications.”

Catalog of STC and IIC Ratings for Wall and Floor/Ceiling Assemblies

“This catalog of sound-rated wall and floor/ceiling assemblies was compiled to enable the user to quickly find a group of construction assemblies having similar sound transmission characteristics. It contains STC assemblies according to the following (Sound Transmission Class) or IIC (Impact Insulation Class) ratings for approximately 500 different construction assemblies ”
