Abstract

The present application discloses a method and device for measuring concealment noise of armored vehicles, which belong to the field of automobiles. The method for measuring concealment noise of an armored vehicle includes: acquiring first sound information collected at a first measurement point and second sound information collected at a second measurement point at the same time; wherein the first sound information The distance between the measurement point and the armored vehicle under test is smaller than the second measurement point; according to the first sound information and the second sound information, it is determined whether the background noise when the first sound information is measured meets the preset requirements If the background noise when the first sound information is measured and obtained meets the preset test conditions, the hearing insensitivity distance for the noise of the armored vehicle under test is determined according to the first sound information. The present application can ensure that in the process of measuring the concealed noise of armored vehicles, the background noise meets the test requirements.

Description

technical field [0001] The application belongs to the technical field of automobiles, and in particular relates to a method and device for measuring concealment noise of armored vehicles. Background technique [0002] The operating noise of armored vehicles is one of the factors affecting the concealment performance of armored vehicles. When testing the concealment noise of armored vehicles, it is generally possible to ensure that the environmental noise (ie background noise) in the test site meets the test requirements, but it is very difficult during the test. It is difficult to ensure that the ambient noise from outside the test site always meets the test requirements. SUMMARY OF THE INVENTION [0003] The purpose of the embodiments of the present application is to provide a method and device for measuring concealment noise of armored vehicles, which can solve the problem that it is difficult to ensure that the environmental noise from outside the test site always meets...
