What is the sound transmission loss of cork?
Best insight from top research papers
The sound transmission loss of cork is influenced by its composition and application. Cork, particularly when used as a resilient layer in lightweight cement-based screeds, has shown promising results in reducing impact noise transmission, as indicated by laboratory measurements conducted on different screed mixtures . Additionally, cork has been utilized in the development of acoustic panels for acoustic ceilings, demonstrating sound absorption coefficients close to 0.50, making it suitable for noise control applications in commercial spaces . While cork exhibits good sound absorption performance, its transmission loss capabilities are not as high as some hard processed woods, such as Pterocarpus soyauxii and Quercus spp., which are recommended for applications requiring sound transmission prevention .

Is wood fibre a sounds absorber?5 answersWood fiber is indeed a sound absorber. Various studies have shown that wood fiber-based materials, such as acoustic absorbers made of polylactic acid (PLA)/polyhydroxyalkanoates (PHA)-wood fibers (PLA/PHA-WF), have good sound absorption properties. The density and porosity of the wood fiber-based materials play a crucial role in their sound absorption capabilities. Thicker materials with higher density tend to exhibit better sound absorption performance, especially in the low- and mid-frequency range. Additionally, the presence of an air back cavity further enhances the sound absorption performance at low frequencies. Wood fiber-based materials, such as fiberboards made from Pinus densiflora wood fibers, have been found to be effective and efficient sound-absorbing materials. These materials meet the required standards and offer eco-friendliness and cost-effectiveness as alternative sound-absorbing options.
What is transmission loss?5 answersTransmission loss refers to the reduction in the volume of water flow in a river as it moves downstream. It is caused by various factors such as infiltration into the riverbed and riverbank, evaporation from the water surface, transpiration by riparian vegetation, and temporary storage in the river and flood plains. These losses play a crucial role in providing ecosystem services, especially in ephemeral and intermittent river systems. Transmission losses can be quantified using different measurement techniques, with one common method being differential gauging of river flow at two locations. Another method, suitable for non-perennial rivers, involves visual assessments of the wetted river length on satellite images. By estimating transmission losses, researchers can improve their understanding of groundwater-surface water interactions and support water management efforts.
How do the physical properties of cork-based sandwich panels affect their thermal conductivity?5 answersThe physical properties of cork-based sandwich panels have a significant impact on their thermal conductivity. The use of cork as the core material in sandwich panels provides several advantages, including low thermal conductivity, high specific strength and stiffness, and excellent damping characteristics. The thermal conductivity of the panels can be evaluated using different methods, such as the guarded-hot-plate, thermal conductivity meter, and heat-flow meter methods. The overall results suggest that cork-based sandwich panels are efficient thermal insulators and can be used to reduce energy consumption in buildings. Additionally, the composition and preparation of the panels can also affect their thermal properties. For example, the use of acidified chitosan as an adhesive in the production of agglomerated cork panels resulted in a thermal conductivity of 0.11W.m-1·K-1. Overall, the physical properties of cork-based sandwich panels, including their density, moisture absorption, and moisture desorption, play a crucial role in determining their thermal conductivity and insulation capabilities.
How do wood acoustic panels absorb sound?5 answersWood acoustic panels absorb sound through various mechanisms. One approach is to use materials such as chips and sawdust of red and beechwood, which have different particle sizes and thicknesses to enhance the absorption coefficient. Particle sizes in the range of 0.31 mm to 2.5 mm show better absorption, while sizes equal to or higher than 5 mm to 8 mm and sizes below 0.16 mm are less efficient. Another method involves combining a sound-absorbing sheet and a honeycomb structure. The sound-absorbing sheet, with a specific air flow resistance, allows for the combination of membrane vibration and sound reciprocation through micropores, resulting in improved sound absorption performance. Additionally, the use of a protection layer made of paint with synthetic resins dispersed in water can reinforce the sound-absorbing body of the panel. These different approaches contribute to the effective absorption of sound by wood acoustic panels.

How is cork able to absorb liquids?4 answersCork is able to absorb liquids through a combination of mechanisms. Experimental evidence suggests that both vapors and liquids can permeate through the small channels across the cells of cork, known as plasmodesmata, as well as through the walls of cork cells by sorption and diffusion. This means that liquids can permeate through cork not only by passing through the channels between cells, but also by being absorbed and diffusing through the cell walls. The cellular structure of cork, with its hollow and closed cells, allows it to slowly absorb water and float on water due to its large buoyancy. The absorption of liquids by cork is influenced by factors such as the equilibrium moisture content of the material, the temperature, and the wettability of cork surfaces by liquids.
