Declared properties8#
ten times the logarithm to the base 10 of the ratio of the square of the sound pressure to the square of the reference sound pressure [p_0 = 20 μPa ]
filter reducing the lowest and highest frequencies of the overall measured sound pressure level
highest value reached by the sound pressure level variing with time
rate per unit time at which airborne sound energy is radiated by a source
ten times the logarithm to the base 10 of the ratio of the sound power radiated by the source under test to the reference sound power [W_0 = 1 pW]
filter reducing the lowest and highest frequencies of the overall measured sound power level
reference to an international standard for the measurement of noise emissions describing the operating and mounting conditions of the machine during measurement, the measurement methods and the form and method for declaring the noise emission values
maximum sound power level determined in accordance with the requirements including the uncertainties due to production, variation and measurement procedures and where the manufacturer, or his authorized representative, confirms that according to the technical instruments applied and referred to in the technical documentation is not exceeded.
