Acoustic Design and Simulation for indoor and outdoor spaces Predicting the sound field in spaces in the build environment, both indoors and outdoors, is of high importance in the field of acoustics, both in design and construction environments. In the industry, prediction methods are indispensable, for example in the development of acoustic related products. Also, …
Sound Masking 101 What is Sound Masking ? Sound masking is the process of adding background sound to reduce noise distractions, protect speech privacy and increase office comfort. Sound masking is ambient background sound engineered to match the frequency of human speech for greater speech privacy. Adding sound to a space actually makes the space seem …
Basic Design of Sound Insulation Between Two Rooms The airborne and impact sound insulation of partitions (walls and floors) and of building elements is normally expressed in terms of a single figure value, based on measurement of the sound insulation over a range of frequencies (typically 50 Hz to 3.15 kHz, although this may be …
Acoustic Value Rw for Building Materials Rw index : The Rw index or sound reduction index (expressed in decibels) measures, in just one number, the acoustic performance of a specific unit. The higher the Rw index, the better the level of acoustic insulation offered by that composition. For instance, the Rw index of ordinary double …
Acoustic Laminated Glass .. A combination of large thickness, different one between the two panes and wide air space distance (even better if we use laminated glass) provides the maximum noise attenuation. We can reach up to 45dB. Combined effect of glass thickness and air space on the acoustic performance of double glazing. Source: Detailing for …
