Abstract

The invention relates to a sound intensity testing bracket, which comprises a bracket base, a vertical rail, a horizontal rail and a sound intensity probe, wherein the vertical rail is vertically arranged on the bracket base; the horizontal rail is vertically arranged on the vertical rail and is arranged horizontally; and the sound intensity probe is movably arranged on the horizontal rail.

Description

technical field [0001] The invention relates to the NVH test belonging to the automobile industry, in particular to a sound intensity test bracket, which can complete the sound intensity test when the sound intensity cannot be measured with a hand-held sound intensity probe. Background technique [0002] When testing sound intensity in the automotive industry, it is very inconvenient to hold a sound intensity probe. And when testing the sound intensity of the engine, the noise near the high-speed engine is very loud, causing damage to people's hearing. In addition, it is very dangerous to test near the high-speed engine. SUMMARY OF THE INVENTION [0003] In view of the above inconvenience, the purpose of the present invention is to provide a sound intensity test stand, so that the tester can complete the sound intensity test away from the engine or the dangerous test position. [0004] Specifically, the purpose of the present invention is to provide a two-dimensional plan...
