Methods of study of acoustic materials and parts with distinct acoustic properties
EDN: TFSGCR
Abstract
Introduction (problem statement and relevance). Testing of acoustic materials depends on the standards used by the manufacturer: the supplier independently selects the methods by means of which it will further classify the new material. This paper describes the acoustic materials testing methods applied by FSUE “NAMI”: bench tests of vibration dampening or cushioning (shock-absorbing) materials, flat and moulded acoustic materials, and parts with distinct acoustic properties to determine noise transmission loss.
The purpose of the study is to create a full complex of FSUE “NAMI” methods for testing and classification of acoustic materials of various types.
Methodology and research methods. The selected research methods based on the standards related to acoustic materials testing.
Scientific novelty and results. In reliance on the complex of methods collected in this paper, one can carry out full efficiency analysis and classification of noise-insulating, noise-absorbing (noise-attenuating) and vibration dampening (shock-absorbing) vehicle materials and products. Previously, such a full list of FSUE “NAMI” research methods has not been covered in the public domain in one publication.
Practical significance. The test methods specified in the paper have been applied in FSUE “NAMI” for several years within work performance under various projects.
