Acoustics - Determination of highfrequency sound power levels emitted by machinery and equipment - Second Edition
N 9295
Annotation
This International Standard specifies four methods for the determination of the sound power levels of high-frequency noise emitted by machinery and equipment in the frequency range covered by the octave band centred at 16 kHz, which includes frequencies between 11,2 kHz and 22,4 kHz. They are complementary to the methods described in ISO 3741 and ISO 3744. The first three methods are based on the reverberation test room technique. The fourth method makes use of a free field over a reflecting plane.
The test conditions which prescribe the installation and operation of the equipment are those specified in ISO 3741 or ISO 3744 as applicable.

Акустика - Определение высокочастотных уровней звуковой мощности, испускаемых машинным оборудованием и оборудованием - Второй Выпуск
Этот Международный стандарт указывает четыре метода для определения уровней звуковой мощности высокочастотного шума, испускаемого машинным оборудованием и оборудованием в частотном диапазоне, покрытом полосой октавы, центрируемой в 16 кГц, который включает частоты между 11,2 кГц и 22,4 кГц. Они дополнительны к методам, описанным в ISO 3741 и ISO 3744. Первые три метода основываются на тестовом методе реверберации помещения. Четвертый метод использует свободное поле по отражающейся плоскости.
