JIS C 1507:2006 电声学.声音强度的测量用仪器.双压力传感扩音器的测量

この規格は，音響ィンテンシティの測定に用いる機器及びそれらに関連する校正器の性能について規定する。この規格は，プロープと処理器の製造業者が異なる場合も含めて.同じ測定を異なる測定器で行うことによって生じる差異を実用的な最小値にまで減少させることを目的としている。この規格は，JIS Z 8736-1に従う音響パワーの測定に用いる音響ィンテンシティ測定器の測定精度の確保を目的とする。JIS Z 8736-1に適合する測定を行うため，測定器は，1/3オクタープパンド又はオクタープパンごとに音響インテンシティ分析できることが必要である。また，オプションのA特性で周波数重み付けしたパンドレべルでの音響ィンテンシティ分析が必要となることがある。測定器には，JIS Z 8736-1に規定する音場指標を容易に算出できるように。音響ィンテンシティレべルとともに，音圧レべルの測定も必要である。この規格は，空間的に離して配置した圧力形ペアマイクロホンによって音響インテンシティを検出すろ測定器にだけ週用する。備考 この規格の対応国際規格を，次に示す。なお，対応の程度を表す記号は，ISO/IEC Guide 21に基づき， IDT(一致している)，MOD（修正している），NEQ(同等でない)とする。

ASTM E1503-06 使用数字统计声分析系统测量室外声级的标准试验方法

1.1 This test method covers the measurement of outdoor sound levels at specific locations using a digital statistical sound analysis system and a formal measurement plan.1.1.1 This test method provides basic requirements for obtaining either a single set of data or multiple sets of related data. However, because there are numerous circumstances and varied objectives requiring multiple sets of data, the test method does not address planning of the measurement program.1.2 The use of results of measurements performed using this test method include, but are not limited to, the following:1.2.1 To characterize the acoustical environment of a site,1.2.2 To characterize the sound emissions of a specific sound source which exhibits a temporal variation in sound output, and1.2.3 To monitor the effectiveness of a noise impact mitigation plan.1.3 This test method is intended to be used in conjunction with a measurement plan that references this test method. Changes or additions to the provisions of this test method shall be clearly stated in the plan.1.3.1 In the event it is necessary, for example, because of time constraints, to conduct measurements without first formalizing a plan, this test method can be used if an operator/observer whose qualifications are satisfactory to both the performing organization and the client is present at all times during the measurements and who complies, to the extent possible, with all the applicable requirements of this test method, including record keeping.1.4 The data obtained using this test method enable comparison of sound level data with appropriate criteria.1.4.1 The data obtained with this test method can be used in the derivation of loudness levels provided the necessary requirements regarding sample duration and signal bandwidth are observed in collecting the data. It is recommended that a specialist in the area of loudness evaluation be consulted in preparing a plan for measurements intended to produce data which will be used for this purpose.1.5 The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information only.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 and health practices and determine the applicability of regulatory limitations prior to use.
