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 tested with a hand-held sound intensity probe. Background technique [0002] It is very inconvenient to hold the sound intensity probe in the automotive industry to test the sound intensity. And when testing the sound intensity of the engine, the noise near the high-speed engine is very loud, causing hearing damage to people. In addition, it is very dangerous to test near the high-speed engine. Contents of the invention [0003] In view of the above inconvenience, the object of the present invention is to provide a sound intensity test bracket, which can complete the sound intensity test by keeping the tester away from the engine or dangerous test position. [0004] Specifically, the object of the present invention is to provide a two-dimensional pl...
