Oitc Rating Chart

Oitc Rating Chart - Web sound transmission class (stc) and outdoor/indoor transmission class (oitc) are measured in decibels (db), and are the standard method for rating sound attenuation characteristics of glass products and window assemblies. Web using what you’ve learned. It is used to specify the sound transmission loss properties of exterior building elements such as walls and windows. Web the oitc is a newer rating system similar to stc that was designed to measure sound transmission loss between a more extensive frequency range from 80 to 4000hz. The lower frequencies are given more weight in all oitc calculations. Web we also use the oitc rating to determine a product’s value for use in low frequency sensitive areas such as home theaters and recording studios. The oitc is the preferred rating for exterior walls and roofs of metal buildings. Web today, the oitc rating system is used to assess any barrier meant to block out low frequency sound.
