LABORATORY MEASUREMENT OF THE AIRBORNE NOISE REDUCTION OF ACOUSTICAL MATERIALS
1989-05-01
HISTORICAL
J1400_198905
This SAE Recommended Practice establishes the test procedure, facilities, and instrumentation for determining the noise reduction characteristics of materials commonly installed in ground vehicles, marine, products, and aircraft to reduce noise levels. This document is intended to provide a means of rank ordering materials by utilizing facilities that do not necessarily meet all of the acoustical requirements in ASTM E 90, Laboratory Measurements of Airborne Sound Transmission Loss of Building Partitions. Latitude is permitted in certain test conditions to allow better correlation with in-use acoustical results.

LABORATORY MEASUREMENT OF THE AIRBORNE SOUND BARRIER PERFORMANCE OF AUTOMOTIVE MATERIALS AND ASSEMBLIES
1990-05-01
HISTORICAL
J1400_199005
This SAE Recommended Practice presents a test procedure for determining the airborne sound barrier performance of materials and composite assemblies commonly installed in surface vehicles and marine products. This document is intended to provide a means of rank ordering barrier materials according to their sound transmission loss. At each test frequency the transmission loss (TL) is projected from the measured noise reduction of the test specimen using a correlation factor (CF). The respective CF for the test condition is determined as the differences between the measured noise reduction (MNR) of a homogeneous limp panel, such as lead, and its calculated field-incidence transmission loss. Latitude is permitted in certain test conditions that do not necessarily conform to all of the acoustical requirements of ASTM E 90.

Laboratory Measurement of Random Incidence Sound Absorption Tests Using a Small Reverberation Room
2021-07-13
WIP
J2883
This SAE Recommended Practice describes a laboratory test procedure for measuring the random incidence sound absorption performance of a material or a part in a small size reverberation room by measuring decay rates. The absorption performance may include sound absorption coefficient of the test sample and or the amount of energy absorbed by the test sample. Materials for absorption treatments may include homogeneous materials, nonhomogeneous materials, or a combination of homogeneous, nonhomogeneous, and/or inelastic impervious materials. These materials are commonly installed in the mobility products and in the transportation systems such as ground vehicles, marine products, aircraft, and commercial industry (in industrial and consumer products) to reduce reverberant sound build-up and thus reduce the noise level in the environment by minimizing reflections off of hard surfaces.
