T/JAMIA 003-2023 吸声系数实验室测量：小型混响舱法

材料的吸声系数是一项重要的材料声学性能指标，其对分析材料在工业生产及生活中应用有重要指导作用。材料的吸声系数测量方法常见的有混响舱法与驻波管法，采用混响舱法测量声音无规入射时的吸声系数，而采用驻波管法测量声音正入射（声音入射角度为90°）时的吸声系数。因在工程及建筑的实际使用过程中声音大多为无规入射，因此实际工程中常使用混响舱法测量材料吸声系数。但在实际需要测量的均为小型不规则试样，不满足标准混响舱法测量所要求的标准试样大小。小型混响舱是声学测量领域的一种专业实验装置，其室内声能密度较为均匀，形成扩散声场，主要用于小型不规则构件（如汽车构件）吸声特性的测量。与标准混响舱相比，具有造价低廉，占地面积较小，方便移动等优点。基于这些优点，小型混响舱能广泛应用于各种小型不规则构件吸声系数的测量。

ASTM F2174-02(2023) 验证声发射传感器响应的标准实践

1.1  This practice is used for routinely checking the sensitivity of acoustic emission (AE) sensors. It is intended to provide a reliable, precisely specified way of comparing a set of sensors or telling whether an individual sensor's sensitivity has degraded during its service life, or both. 1.2  The procedure in this practice is not a “calibration” and does not give frequency-response information. 1.3  The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.4  This practice does not purport to recommend one sensor manufacturer over another nor does it imply that one type of sensor will react differently from another when using this procedure. 1.5  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. 1.6  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.

ASTM E1932-12(2022) 小型零件声发射检验标准指南

1.1 This guide covers techniques for conducting acoustic emission (AE) examinations of small parts. It is confined to examination objects (or defined regions of larger objects) where there is low AE signal attenuation throughout the examination region. This eliminates the consideration of complex attenuation factor corrections and multiple sensor and array placements based on overcoming signal losses over distances. 1.2 The guide assumes a typical AE examination as one where there is a controlled or measured stress acting upon the part being monitored by AE. Particular emphasis is placed on sensor and system selection, sensor placements, stressing considerations, noise reduction/rejection techniques, spatial filtering, location determination, use of guard sensors, collection of AE data, AE data analysis and report. The purpose of the AE examination is to analyze how an object under evaluation is withstanding the applied load. 1.3 Possible applications of this guide includes materials characterization, quality control of production processes, proof testing after fabrication, evaluating regions of interest of larger structures and retesting after intervals of service. The applied load may include mechanical forces (tension, compression or torsional) internal pressure and thermal gradients. 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.
