Abstract
Aim of study: To determine the sound transmission losses of 16 different wood species with the different density in the range of 100-1000 Hz frequencies, and the relationship between density and transmission loss was. Material and methods: In this study sound transmission loss values of Ash (Fraxinus excelsior), Acacia (Robinia pseudoacacia L.), Beech (Betula pendula), Black pine (Pinus nigra), Black poplar (Populus nigra), Canadian poplar (Populus x euramaricana), Chestnut (Castanea sativa Mill.), Cypress (Cupressus sempervirens), Oriental beech (Fagus orientalis Lips,) Eucalyptus C. (E, camaldulensis Dehnh), Eucalyptus G. (Eucalyptus grandis), Juniper (Juniperus excelsa), Plane (Platanus orientalis L.), Scotch pine (Pinus sylvetris L), Turkish Red pine (Pinus brutia Ten) and White Oak (Quercus alba) wood specimens were determined by using the impedance tube kit. Main results: Sound transmission loss is observed in lower density wood material species with the increasing frequency. However, a clear relationship has not been established between the mean sound transmission loss and density. Highlights: It is important to determine the frequency-related acoustic performance parameters of the wood material and to its relationship with density.
