Thermal and sound insulation performance assessment of vacuum insulated composite insulation panels for building façades [PDF]
, 2018 Composite insulation panels (CIPs) currently used in building façades require significant design changes e.g. increased thickness to realise higher thermal and sound insulation performance.

Energy-Efficient Low-Complexity Algorithm in 5G Massive MIMO Systems [PDF]
, 2021 Energy efficiency (EE) is a critical design when taking into account circuit power consumption (CPC) in fifth-generation cellular networks. These problems arise because of the increasing number of antennas in massive multiple-input multiple-output ...

An empirical model for the equivalent translational compliance of steel studs [PDF]
, 2012 The effect of the resilience of the steel studs on the sound insulation of steel stud cavity walls can be modeled as an equivalent translational compliance in simple models for predicting the sound insulation of walls.

Sound fields near building facades: comparison of finite and semi-infinite reflectors on a rigid ground plane [PDF]
, 2009 The sound field in front of, and close to a building facade is relevant to the measurement and prediction of environmental noise and sound insulation. For simplicity it is often assumed that the facade can be treated as a semi-infinite reflector, however

Breaking the mass law for broadband sound insulation through strongly nonlinear interactions
New Journal of Physics, 2023 Sound transmission through panels is governed by the well-known mass law in the mid-frequency range. This paper reveals a possibility of breaking this density-dominant law through strongly nonlinear interaction, while broadening the bandwidth for ...

The improvement of a simple theoretical model for the prediction of the sound insulation of double leaf walls [PDF]
, 2010 This paper presents a revised theory for predicting the sound insulation of double leaf cavity walls that removes an approximation, which is usually made when deriving the sound insulation of a double leaf cavity wall above the critical frequencies of ...

Sound insulation at low frequencies [PDF]
The Journal of the Acoustical Society of America, 1972 The transmission of airborne sound between two rooms coupled by a panel is investigated. At low frequencies individual modes in the rooms and the panel control the transmission. It is shown that resonant modes in the room are the chief cause of frequency-dependent variations in low-frequency sound insulation.

Influence of loudspeaker directivity on the measurement uncertainty [PDF]
, 2011 One of the most significant aspects of a building’s acoustic behavior is the airborne sound insulation of the room façades, since this determines the protection of its inhabitants against environmental noise.

An experimental study on the effect of rolling shutters on the field measurements of airborne sound insulation of façades [PDF]
, 2013 The façade is the visible part of a building, and generally consists of various different constructive systems. The sound reduction index of the closing elements for the openings on a room’s façade is a determining factor in the sound insulation from ...
