Abstract

Çalışmanın amacı: farklı yoğunluğa sahip 16 farklı ağaç türünün 100-1000 Hz frekans aralığında ses iletim kaybı değerleri ile yoğunluk arasındaki ilişkinin belirlemektir.
Materyal ve yöntem: Bu çalışmada Dişbudak (Fraxinus excelsior), Akasya (Robinia pseudoacacia L.), Huş (Betula pendula), Karaçam (Pinus nigra), Kara kavak (Populus nigra), Kanada kavağı (Populus x euramaricana), Kestane (Castanea sativa) Mill.), Selvi (Cupressus sempervirens), Doğu kayını (Fagus orientalis Lips,) Okaliptüs C. (Eucalyptus camaldulensis Dehnh), Okaliptüs G. (Eucalyptus grandis), Ardıç (Juniperus excelsa), Doğu Çınarı (Platanus orientalis L.), Sarıçam (Pinus sylvetris L), Türk Kızılçamı (Pinus brutia Ten.) ve Beyaz Meşe (Quercus alba) odunlarının ses iletim kaybı değerleri empedans tüp düzeneğinde belirlenmiştir.
Temel sonuçlar: Frekans arttığında, daha düşük yoğunluğa sahip ağaç malzeme türlerinde yüksek ses iletim kaybı gözlendiğini belirlenmiştir. Ancak, ortalama ses iletim kaybı ile yoğunluk arasında net bir ilişki belirlenmemiştir.
Araştırma vurguları: ağaç malzemenin frekansa bağlı akustik performans parametrelerinin belirlenmesi ve yoğunluk ile ilişkisinin tespit edilmesi önemlidir.

Experimental Determination of Sound Transmission Loss of Some Wood Species

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.
