The International Building Code (IBC) is a uniform model law that governments adopt as their own to regulate the construction, design and installation of buildings within their jurisdiction. The IBC is intended to safeguard the health, safety and welfare of the public. The IBC is published every three years.
Section 1207 of the 2000 edition of the IBC is titled "Interior Space Dimensions."
Section 1207 of the 2003 edition, and subsequent editions, of the IBC is titled "Sound Transmission."
Chapter 12
The 12th chapter of the IBC deals with interior environments of buildings. It covers such topics as lighting, ventilation, temperature, sound, space and rodent proofing.
Section 1207 of 2000
The original IBC was published in 2000. Section 1207 (Interior Space Dimensions) is divided into four subsections. The first is 1207.1 (Minimum Room Widths). The second is 1207.2 (Minimum Ceiling Heights). The third is 1207.3 (Room Area). The fourth is 1207.4 (Efficiency Dwelling Units).
This section 1207 was renumbered as section 1208 in the 2003 edition.
Section 1207 of 2003
The 2003 section 1207 on sound transmission is divided into three subsections. The first is 1207.1 (Scope). The second is 1207.2 (Air-Borne Sound). The third is 1207.3 (Structure-Borne Sound).
This section 1207 was numbered as section 1206 in the 2000 edition.
Air-Borne Sound
The IBC governs the amount of noise that is allowed to be transmitted within, and through, the interior walls of a building. In short, it makes sure that the acoustics of a building fall within an acceptable range. To do this, it requires construction contractors to conduct a test known as the Standard Method Test for Laboratory Measurement of Airborne Sound Transmission (also known as the ASTM E 90).
The acceptable rating of sound transmission class (STC) is not less than 50 (45 if field tested).
Structure-Borne Sound
In addition to the acoustics of a building, the IBC also deals with the amount of noise that can be transmitted through interior floors and ceilings. To do this, it requires construction contractors to conduct a test officially known as the Standard Test Method for Laboratory Measurement of Impact Sound Transmission Through Floor-Ceiling Assemblies Using the Tapping Machine (also known as the ASTM E 492).
The acceptable rating of impact insulation class (IIC) is not less than 50 (45 if field tested).
