| What is 1/3 Octave Band Equalization Tuning? | ||||
|
|
Unlike a fixed sound masking spectrum for all applications, this process precisely fills in one-third octave band attenuation deficiencies for the specific application, and generates and contours a precise computer generated sound masking spectrum for optimum performance.
As per the ASTM, American Society of Testing and Materials definition of "True sound masking".
Acoustical privacy is accomplished by a combination of voice levels, sound attenuation, and background levels. The sound attenuation factor is a property of the building structure and cannot be changed, once installed. The background sound levels are set with a masking sound spectrum that is designed to complement the sound attenuating factors such that a specific degree of privacy is obtained. This computer tuning process assures the maximum degree of speech privacy at the lowest possible background sound.
