| Название (рус.): | Акустика. Определение уровня звуковой мощности источников шума. Требования для изготовления и калибровки эталонных источников звука |
| Название (англ.): | Acoustics; determination of sound power levels of noise sources; requirements for the performance and calibration of reference sound sources |
| Описание (англ.): | Specifies the essential acoustical performance requirements and procedures for calibrating a sound source in terms of its sound power level in octave and one-third octave bands and with frequency weighting A. To achieve uniform and accurate results it is required that the calibration be performed in the acoustic environment provided by a hemi-anechoic room, i. e. a free field over a reflecting plane. Applies to a soundsource which is manufactured for use as a reference sound source. |
