ASTM D7145-22 用声学方法测量大气风和湍流剖面的标准指南

1.1 This guide describes the application of acoustic remote sensing for measuring atmospheric wind and turbulence profiles. It includes a summary of the fundamentals of atmospheric sound detection and ranging (sodar), a description of the methodology and equipment used for sodar applications, factors to consider during site selection and equipment installation, and recommended procedures for acquiring valid and relevant data. 1.2 This guide applies principally to pulsed monostatic sodar techniques as applied to wind and turbulence measurement in the open atmosphere, although many of the definitions and principles are also applicable to bistatic configurations. This guide is not directly applicable to radio-acoustic sounding systems (RASS), or tomographic methods. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this guide. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This technical report applies to loudspeakers conforming to IEC 61305-5 and intended for home use. The purpose of this report is, in addition to objective testing according to IEC 60268-5, to establish standards for comparison of the sound characteristics of various loudspeakers with each other. Two test procedures are described: – single stimulus ratings; – paired comparisons. The procedures described in this report are applicable to any number of channels. NOTE The test procedures are specified for stereo systems. They can be applied to multichannel systems accordingly.

The document specifies methods for the determination of the sound insulation performance of sound-insulating cabins by measurements under laboratory or in-situ conditions. The sound insulation is the reduction in sound power level or sound pressure level effected by the cabin. The methods can be applied to closed cabins or cabins with little leakage. Only complete cabins (as opposed to building elements) can be measured according to the document. The requirements for the measurement environment are based upon those of ISO 3741.
