Abstract

The invention relates to a method for detecting flushing noises of a floor type ceramic pedestal pan. The detection steps include experimental facility requirements, sample installation and debugging,determination of the outdoor rectangular measurement surface of a sound source, sound pressure level measurement, level-of-effective-perceived-noise calculation and background noise and test environment correction, and result evaluation. The method is specially characterized in that the flushing noises of the floor type ceramic pedestal pan, represented by the level of effective perceived noise (LEPN), on the outdoor rectangular measurement surface of the sound source are accurately and quantitatively detected by applying a fast time weighting characteristic "F" and a function key "peak" of the A weighting equivalent sound level of a sound level meter. It is stipulated that the A weighing time average maximum sound pressure level L'pAi(ST)(max) of the flushing noises on the outdoor rectangular measurement surface of the sound source and the A weighting cumulative percentage time average sound pressure level LpAi(B)(50) of background noises are measured; the LEPN of the floor type ceramic pedestal pan in a normal flushing period is calculated; and meanwhile, a result evaluation basis is provided. The method fills the blank of the technical field of pedestal pan flushing noise detection; the scientificity of the method and the comparability of a result are achieved; and the technical support can be provided for ceramic enterprises to improve production processes and standardizemarket order.

Description

technical field [0001] The invention relates to a noise quantitative testing method, in particular to a sound level meter using the fast time weighting characteristic "F" and the function key "peak" to measure the noise level L effectively on the outdoor rectangular measurement surface of the sound source. EPN The invention discloses a method for detecting the flushing noise of a characterized floor-type ceramic toilet, and belongs to the technical field of ceramic physical and chemical performance detection. Background technique [0002] In recent years, as a basic livelihood issue and an important window of civilization, the construction quality of toilets cannot be ignored. With the increasing use of floor-standing ceramic toilets in catering, tourism, home and other key areas of people's livelihood and the enhancement of people's awareness of health and environmental protection , toilet flushing noise monitoring and prevention and control have increasingly received wides...
