Problems solved by technology

There are also more and more test devices for sound insulation testing of vehicle materials and test devices for sound insulation testing of vehicle components on the market. However, these test devices only perform sound insulation on a certain part of the vehicle. The test cannot reflect the absorption and sound insulation effect of the whole vehicle
Moreover, there will be various operating conditions during the actual operation of the vehicle, and these test devices cannot meet the test requirements of the vehicle under different operating conditions.

Abstract

The invention relates to a vehicle sound absorption and insulation performance tester which comprises a data processor and first and second data collectors. The first data collector is mounted in an engine during use, the second data collector is mounted in a compartment during use, both the first and second data collectors are in communication connection with the data processor, and each data collector comprises a sound pressure measuring probe. The tester can measure the sound insulation effect of the whole vehicle, can move with the vehicle, and measures sound absorption and insulation performances of the vehicles in different conditions of practical operation, and a measurement result can be used to reflect the practical sound insulation effect of the vehicle more.

Description

technical field [0001] The invention relates to a testing device for vehicle absorption and sound insulation performance. Background technique [0002] As people's requirements for vehicle comfort are increasing day by day, more and more people pay attention to the performance of vehicle absorption and sound insulation. There are also more and more test devices for sound insulation testing of vehicle materials and test devices for sound insulation testing of vehicle components on the market. However, these test devices only perform sound insulation on a certain part of the vehicle. The test cannot reflect the sound absorption and sound insulation effect of the whole vehicle. Moreover, there will be various operating conditions during the actual operation of the vehicle, and these test devices cannot meet the test requirements of the vehicle under different operating conditions. Contents of the invention [0003] The object of the present invention is to provide a vehicle...
