“…However, such a window design is not suitable for use in tropical or sub-tropical regions. Bajraktari et al [63] showed that their double-facade system, which was basically a plenum window setup, could offer a noise reduction, R w , of between 18 to 26 dB, when no sound absorption material was applied.…”

Abstract:This review summarizes the current status of the research and development of natural ventilation-enabling noise control devices for use on the façades of high-rise residential buildings in congested cities. These devices are important for a sustainable urbanized city, as they are supposed to offer good acoustical protection to citizens, allowing for an acceptable level of natural ventilation inside residential units; energy for mechanical ventilation can then be saved. From the information presented in the existing literature, it is concluded that protrusive devices, such as lintels and balconies, are not effective noise screening devices, even if they are installed with sound absorbers and/or reflectors, under the effect of city reverberation. On the contrary, plenum windows and similar structures, which are plenum structures with a staggered air inlet and outlet, are interesting alternatives that are worth rigorous considerations.

“…Kajian tentang target electroplating LEU yang optimum di reaktor RSG-GAS telah dilakukan oleh Pinem et al [10]. Penelitian dilakukan dengan optimasi untuk target tunggal ataupun campuran dengan target radioisotop (RI) lainya, seperti TeO2 (menghasilkan 131 I) [11,12], Gd2O3 (menghasilkan 161 Tb) [13], MoO3 dan Sm2O3 (menghasilkan 153 Sm). Posisi iradiasi divariasi jumlahnya untuk IP (Irradiation Position, 4 posisi kisi teras) dan CIP (Central Irradiation Position, 4 posisi kisi teras).…”

“…Bibby et al looked into the use in practice of ventilation grill acoustic silencers [55]. The influence on the acoustic performance of DFTs of the spacing of the vents and of absorptive materials applied in the cavity was studied in [56,57]. Also extensive comparative studies of the acoustic performance of different DSF types have been carried out [58][59][60].…”

The sound insulation spectrum is analysed of 18 double glazing arrangements facades, of which 9 double skin facades were measured in situ and 9 in a laboratory setting. The influence of the cavity thickness, the parallelism of the two glass panels, the absorptivity of the cavity and the effect of the size of ventilation slots are investigated. The results are compared with double layer wall insulation prediction models. Also a new, simple model is proposed that predicts the sound insulation of naturally ventilated double skin facades, based on the coincidence frequency, the structural resonance frequencies, the cavity resonance frequencies, the façade construction, the dimensions the and material properties. The model predictions are validated by measurement data.
