Forage density effect on sound insulation properties

Grass and Forage Science, 2010
AbstractOne of the main parameters affecting forage management and quality is density. Existing methods used for measuring physical properties of forage involve costly destructive analysis. A frequent and appropriate control of the forage density is required for optimizing the management of silage, hay and straw production; therefore, there is a need ...

Prediction on sound insulation properties of ultrafine glass wool mats with artificial neural networks

Applied Acoustics, 2019
An artificial neural network (ANN) technique was applied to predict the sound insulation properties of ultrafine glass wool mats. Based on an experimental database for glass wool mats, sound transmission loss (STL) in the frequency of 1000 Hz, 2000 Hz ...

Thermal and sound insulation properties of pumice/polyurethane composite material

Emerging Materials Research, 2020
This study aimed to create a flexible composite material that can be used in special environments where heat and sound insulation is desired. Pumice with a grain size of 4.76–2.38 mm was mixed with 10, 20, 30, 40 and 50% polyurethane by volume. Sound absorption coefficient, sound transmission loss coefficient and thermal conductivity coefficient tests ...

Sound insulation properties of sandwich structures on glass fiber felts

Fibers and Polymers, 2015
This paper focuses on three types of glass fiber felt sandwich structures to identify the optimal sound insulation structure. Air flow resistivities of glass fiber felts are 6633 Pa·s/m2 (Loose), 19579 Pa·s/m2 (Mid) and 42724 Pa·s/m2 (Dense), respectively. The three types of sandwich structures are dense-mid-loose (DML), mid-loose-dense (MLD) and loose-
