BS EN 60268-4:2004 音响系统设备.传声器

This part of IEC 60268 specifies methods of measurement for the electrical impedance, sensitivity, directional response pattern, dynamic range and external influences of sound system microphones, and also gives recommendations as to characteristics to be specified. It applies to sound system microphones for all applications for speech and music. It does not apply to measurement microphones, but it does apply to each audio channel of microphones having more than one channel, for example for stereo or similar use. It is also applicable to flush-mounted microphones and to the analogue characteristics of microphones with digital audio output. For the purposes of this International Standard, a microphone includes all such devices as transformers, pre-amplifiers, or other elements that form an integral part of the microphone, up to the output terminals specified by the manufacturer. NOTE The characteristics specified in this standard do not completely describe the subjective response of the microphone. Further work is necessary to find new definitions and measurement procedures for a later replacement by objective characteristics of at least some of the subjective descriptions use to describe microphone performance.

DIN EN 60942:2004 电声学.音响校准器

This International Standard specifies the performance requirements for three classes of sound calibrator: laboratory standard (class LS), class 1 and class 2. Tolerance limits are smallest for class LS and greatest for class 2 instruments. Class LS sound calibrators are normally used only in the laboratory; class 1 and class 2 are considered as sound calibrators for field use. Revision of the IEC standard of 1997-11 provides correct consideration of the measurement uncertainty of the testing laboratory and contains additional requirements concerning EMC.#,,#

この規格は，音響校正器の三つのクラス，クラスLS(実験室用標準)，クラス1及びクラス2の性能要求事項について規定する。クラスLSに対する許容限度値が最も小さく.クラス2に対する許容限度値が最も大きい。クラスLSは，通常，実験室内でだけ使用する音響校正器，クラス1及びクラス2は，現場で使用する音響校正器である。クラス1の音響校正器は，IEC 61672-1に規定するクラス1の騒音計とともに用い，クラス2の音響校正器は，クラス2の騒音計とともに用いることを想定している。クラスLSの音響校正器についてこの規格への適合性を評価する場合には，IEC 61094-1に規定する標準マィクロホンの使用を前提として，この規格の許容限度値を規定している。クラス1又はクラス2の音響校正器についてこの規格への適合性を評価する場合には，IEC 61094-4に規定する計測用マイクロホンの使用を前提として，この規格の許容限度値を規定している。複数の音圧レべル及び複数の周波数の音を発生すろ音響校正器は，この規格に適合すろと取扱説明書に記載された音圧レべル及び周波数のすべての組合せで，同じクラス表示をもつ。サウンドレペルメータ全体の感度を調整するために用いられることのあろ，等価自由音場音圧レべル又は等価ランダム入射〔拡散音場)音圧レベルについての要求事項は，この規格では規定しない。音響校正器は，トーンバーストを発生させるような，他の機能を内蔵してもよい。このような他の機能についての要求事項は，この規格では規定しない。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。
