The STC rating for a basic wood structure floor/ceiling is 40-43. 2. 2015 (Mediastika et al Discusses the acoustical properties of glass, methods of rating, such as STC and OITC, applicable standards and the relationship between glass and other glazing components in determining an overall rating. It uses a specific decibel (Db) range (80 Hz to 4000 Hz) which makes it a better measure for low sound frequencies such as road noise. The Delta IIC rating is the best sound rating to consider when comparing the performance of different types of underlayment The updated version of this Standard provides minimum requirements for rating masonry walls for sound transmission class (STC) and outdoor-indoor transmission class definitions and notations, materials, construction, and methods to STC and OITC rating for concrete masonry and clay masonry assemblies.

Department of Housing and Urban Development (HUD) provides information on housing policies, programs, and resources. Explore noise reducing windows and doors from Pella. The OITC rating is thus more applicable to garage doors than the STC rating. This Outdoor-Indoor Transmission Class (or OITC) is a relatively new way of measuring sound transmission, an OITC rating is designed to account for sound transmission from typical ViraconAcousticPerfDataTables. 3% rate as a result of a verifiable NiS inclusion, Viracon will replace the broken heat soaked tempered glass without charge, FOB nearest shipping point to the place of installation and pay for the costs of reasonable market replacement labor.

However, Referring to the typical STC 30 rating chart below, STC is determined by testing sound transmission decibel loss at 16 standard frequencies from 125 to 4000 Hertz (Hz). Two common ratings for windows and doors are the Sound Transmission Class (STC) and Outdoor-Indoor Transmission Class (OITC) Ratings. Check Your Local Replacement Window Regulations When considering replacing windows in your home, it’s COMPARISON CHART The charts below show comparisons between various types of glass and insulated glass units and also between the Rw, Rw+C & Rw+Ctr indices.
