sound transmission class (stc)
A system devised by the ASTM in 1961 to describe how well various types of interior walls floors doors etc. Shop Acoustic Panels Clouds Baffles At Audimute.

An STC rating of 20 is considered very poor while a rating of 60 is considered excellent.
. Sound transmission class STC describes the ability of a product or material to stop the transmission of airborne sound. The higher the STC the better the partition is at reducing sound transmission between spaces. The higher the STC number the greater a materials ability to block sound.
Sound Transmission Class STC A measure for rating the performance of a wall system as a barrier to airborne sound transmission between adjacent closed spaces such as offices. Sound Transmission Class STC ratings of glass indicate how well a partition or construction element mitigates or blocks sound and reduces noise. STC accounts for sound measured between 125 Hz to 4000 Hz.
Sound Transmission Class or STC is the rating system by which the ability of a partition to attenuate reduce the effect of airborne sound is measured. Choosing the best material for your application is dependent upon insulation requirements intended usage acoustics and other conditions. Since the 1960s STC ratings have been used to describe the acoustical properties of ceilings walls floors and doors.
Today STC values are provided for acoustic insulation made from a single material and for multi-layer composites. The Sound Transmission Class STC measured in decibels is used to measure building materials ability to absorb sound. Prevent sound in one room from reaching another.
The STC of a wall is determined by comparing sound transmission loss STL values at various frequencies to a standard contour. A wall system with an STC 35 is considered low performance whereas one with an STC 55 is considered high performance. The STC can be used to measure sound absorption for both external building walls and internal walls in single and multifamily structures.
A Sound Transmission Class STC rating is therefore an instrument measurement of how much noise is stopped. Sound Transmission Class STC is an integer rating of how well a building partition attenuates airborne sound. Sound Transmission Class STC is used to measure a building materials ability to reduce sound.
Understanding STC Sound Transmission Class Simply explained the Sound Transmission Class or STC rating for a material tells you about how much sound that material can block. Sound decibels dB are a measure of sound intensity. Although these ratings are in general use it is also important to examine the third octave band transmission loss data that form their basis and to compare them to the theoretical predictions discussed previously.
Sound transmission class. To reflect the fact that insulation is different at different frequencies the ISO standard defines two additional coefficients with different frequency curve. STC or sound transmission class is defined as the level of reduction of sound transmission from outside noise sources to the building interior.
Ad Eco-Friendly Sound Solutions. Sound Transmission Class STC is a standardized rating measuring reduction in sound decibels dB based on different wall or ceiling assemblies. Sound transmission class STC provides an estimate of the acoustic performance of a wall in certain common airborne sound insulation applications.
For example if you were in a room where a wall joining an adjacent room had an STC rating of. Volume Control For The Real World. As we can tell from the process used to rate the Sound Transmission Class of a wall it is possible to have 2 walls with slightly different curves but both having the same STC rating.
In the USA it is common to measure the STC of a wall by mounting an STC meter on one side and playing white noise through a speaker on the other side while recording the sound levels with a microphones The STC value is then calculated from. They are then assigned STC ratings a United States standard since 1961. Free Of Foam Fiberglass Formaldehyde.
The Sound Transmission Class STC is a single-number rating of the sound isolation of a wall or floor-ceiling assembly. In the USA it is widely used to rate interior partitions ceilings and floors doors windows and exterior wall configurations see ASTM International Classification E413 and E90. Higher STC numbers mean higher resistance to sound transmission to the building interior or as acousticians would describe it higher STC means greater sound transmission loss between outdoors and the building interior.
STC is the wall equivalent of CAC. STC See also impact insulation class. The Sound Transmission Class STC is an integer rating of how well a building material absorbs sound.
Materials are tested over multiple sound frequencies from bass levels of 125Hz to treble levels of 4000Hz. 1 If Wall A has a Sound Transmission Class of 60 STC 60 and Wall B also has an STC 60 of 60 they are exactly the same. The higher the STC rating the more efficient the construction will be in reducing sound transmission within the frequency range of the test.
The STC is measured by positioning a representative. The decibel reduction in noise that a materialpartition may give abbreviated dB is used to calculate STC. Ther Rw is more common in Europe when STC is more common in USA.
What is Sound Transmission Class. Sound Transmission Class STC is a single-number rating of the airborne sound transmission loss TL performance of a constructed assembly measured at standard one-third octave band frequencies. Technically speaking STC is a measurement that is used to determine how effective soundproofing materials are at minimizing sound transmission between rooms.
For architects delving into the zany fun-filled world of sound abatement another acronym that will pop up sooner rather than later is the OITC OutdoorIndoor. Higher STC ratings translate into more reduction in sound. The Sound Transmission Class STC ratings of various construction elements are of considerable interest to architects and acoustical engineers.
The method of measuring the sound transmission class STC is defined by the ASTM E413-87 standard.
