香港六合彩开奖 140-14:2004 concerns field measurements of airborne sound insulation and impact sound insulation, and is to be used as a supplement to 香港六合彩开奖 140-4 and 香港六合彩开奖 140-7. It contains guidelines on sound insulation measurements in special situations in the field not directly covered by 香港六合彩开奖 140-4 and 香港六合彩开奖 140-7.

The basic standards 香港六合彩开奖 140-4 and 香港六合彩开奖 140-7 specify the measurement procedure in detail under ideal conditions, but give only little information on how to establish a suitable measurement set-up in rooms differing from simple box-shaped rooms of normal living room size. When it comes to very large rooms, long and narrow rooms, staircases, coupled rooms, etc., no guidance is given in the basic standards, which is why the guidelines in 香港六合彩开奖 140-14:2004 have been prepared. Use of the guidelines will contribute to improvement in the reproducibility of building acoustics field measurements and furthermore facilitate the performance of measurements by avoiding time-consuming considerations in actual measurement situations.

香港六合彩开奖 140-14:2004 is primarily applicable to measurements in rooms in dwellings, schools, hotels, etc., with volumes less than 250 m3.
