Class 1 Standards: noiseLAB is designed to conform to EN 61672-1 Class 1 for free-field applications.
The filters in noiseLAB conform to EN 61260 Class 1.
The user is responsible for using Class 1 conformant Microphones, Preamps, Calibrators and Digitizers/Recorders with noiseLAB, as well as ensuring the required periodical calibration of the system and its components.
Tone Analysis: Conformant to ISO 1996-2 Annex C. This standard is also referred to in multiple national and international standards.
BS 4142: The standard references the relevant EN standards for Class 1 measurements. These measurements can be used by the user to derive the ratings described in Annex A of the standard.
Annex C describes the “objective” method for Assessing audibility of tones using the one-third octave method. noiseLAB provides these third octave analysis, tp which the user can apply the simple requirements of Annex C.
Annex D for tones is based on ISO 1996 2 and is fully supported in noiseLAB. This method was originally developed by DELTA.
Annex E for impulsive sounds in fully supported by noiseLAB. This method is based on the Nordtest Method ACOU 112 which also was developed by DELTA.
