This document describes a test method for measuring a quantity representative of the intrinsic characteristics of airborne sound insulation for traffic noise reducing devices: the sound insulation index. The test method is intended for the following applications: - determination of the intrinsic...
1.1 This practice covers a guide for the multivariate calibration of infrared (IR) spectrophotometers and Raman spectrometers used in determining the physical, chemical, and performance properties of petroleum products, liquid fuels including biofuels, and lubricants. This practice is applicable to...
5.1 The spectrum of the noise produced in the receiving room by the standard tapping machine is determined by (1) the size and the mechanical properties of the floor-ceiling assembly, such as its weight, surface properties, mounting or edge restraints, stiffness, and internal damping; (2) the...
1.1 This test method uses specific automatic particle counters (APCs) to count and measure the size of dispersed dirt particles, water droplets and other particulates, in light and middle distillate fuel, in the overall range from 4 µm(c) to 70 µm(c) and in the size bands >e;4 µm(c),...
This Recommendation defines error-correction, data framing, modulation and emission methods for terrestrial multimedia broadcasting for mobile reception using handheld receivers in the VHF/UHF bands.
This document a) defines single-number quantities for airborne sound insulation in buildings and of building elements such as walls, floors, doors, and windows, b) takes into consideration the different sound level spectra of various noise sources such as noise sources inside a building and traffic...
This Recommendation describes the planning criteria, which could be used for planning of terrestrial digital sound broadcasting in the MF band, including DRM and IBOC (HD Radio) Digital Systems in Recommendation ITU-R BS.1514.
This document describes two procedures for determining whether or not noise emissions contain prominent discrete tones: the tone-to-noise ratio method and the prominence ratio method. Discrete tones occurring at any frequency within the one-third-octave bands having centre frequencies from...
PURPOSE Delta Differential One-Way Ranging (Delta-DOR) is a Very Long Baseline Interferometry (VLBI) technique that can be used in conjunction with Doppler and ranging data to improve spacecraft navigation by more efficiently determining spacecraft angular position in the plane of sky. It involves...
