Stc Tables, Oct 10, 2025 · The Sound Transmission Class table below, inspired by the one from Mecanum, a manufacturer of noise and vibration control instruments, shows how different STC ratings perform. The STC rating very roughly reflects the decibel reduction of noise that a partition can provide Jan 5, 2025 · What STC ratings really mean across walls, doors, and windows, the assemblies that hit common targets (STC 35 to 60+), code minimums by building type, and the lab-to-field penalty that catches projects off guard. Nov 30, 2025 · The STC rating is important when you are trying to reduce the amount of sound entering or leaving a room. Sound Transmission Class (STC) is an integer rating of how well a building partition attenuates airborne sound. * The field test evaluates the dwelling's actual construction and includes all sound paths. Get accurate results for sound transmission class calculations. Products and corresponding data in this document are intended to provide comparative estimates between glass configurations. In the US, it is widely used to rate interior partitions, ceilings, floors, doors, windows and exterior wall configurations. Before you create STCs, you need to calculate how many STCs your system is eligible for. The standard requires a minimum laboratory STC rating of 50 for party walls and floor/ceilings. STC RATINGS FOR VARIOUS WALL ASSEMBLIES Below are the STC ratings of various wall assemblies, each presented to help illustrate concepts, improvements and rules of thumb. The estimated ratings are based on laboratory test results from various compendiums of STC ratings. Apr 30, 2026 · Under the Small-scale Renewable Energy Scheme, eligible systems can earn small-scale technology certificates (STCs). With the widest offerings on the market and a customer service staff ready to offer full support , we are confident you’ll find the appropriate sound-control solution you need for your project. TABLE OF CONTENTS We would like to show you a description here but the site won’t allow us. SITE EXTERIOR NOISE - OITC/STC of façade (H,OP,R) Issue: Outdoor Indoor Transmission Class criteria are more appropriate than STC for façade evaluation, but test data are sparse Resolution: 2010 Guidelines listed STC, 2014 Guidelines listed OITC, 2018 will list both providing guidance on how to select. Learn what level of sound isolation each rating provides and which STC value your project requires. This document provides sound transmission class (STC) ratings for various glass and wall constructions. All too often this plenums and suspended ceilings unbaffled ducts window to window (outdoors) common heating units transoms and air grilles unblocked joist spaces uncaulked wall perimeters ducts, piping and fixtures masonry joints Can increase the STC rating of a double-layer, steel-framed partition from 29 to 53 STC An integral part of high-performance USG partition designs for attenuation of low-frequency sound from machinery and music Suitable for use at the perimeter of fire-rated wall assemblies For more information see the following brochure: Calculated values of STC are listed in Table 1.
