Investigation Of Sound Absorption Properties Of Bark Cloth Nonwoven Fabric And Composites [PDF]
The quest for sound-absorbing materials that are not only environmentally friendly, but also sustainable is the foremost reason for natural fibre-acoustic materials. Bark cloth is a natural non-woven fabric that is largely produced from Ficus trees.

Spatial Sound in a 3D Virtual Environment: All Bark and No Bite? [PDF]
Although the focus of Virtual Reality (VR) lies predominantly on the visual world, acoustic components enhance the functionality of a 3D environment. To study the interaction between visual and auditory modalities in a 3D environment, we investigated the

The Tai Ahom Sound System as Reflected by the Texts Recorded in the Bark Manuscripts
Tai Ahom (Southwestern Tai) mostly survives in manuscripts. (Terwiel 1988; Morey 2015). It has long been held that Ahom retained many archaic features lost in most modern Tai languages.

Sound-Absorption Coefficient of Bark-Based Insulation Panels [PDF]
The objective of this study was to investigate the sound absorption coefficient of bark-based insulation panels made of softwood barks Spruce (Picea abies (L.) H. Karst.) and Larch (Larix decidua Mill.) by means of impedance tube, with a frequency range between 125 and 4000 Hz.

Sound production in bark and ambrosia beetles [PDF]
Bark and ambrosia beetles and pinhole borers (Coleoptera: Curculionidae: Scolytinae and Platypodinae) are two subfamilies of weevils that use acoustic communication within plant tissue. These insects transmit and detect sound in a medium that is neither air nor water and they are among the smallest animals with sound-producing organs.

Sound absorption by tree bark [PDF]
Abstract Scattering of sound waves by trunks is a main physical factor leading to sound pressure level reduction by tree belts, and it has been shown before that the absorbing properties of the trunks are relevant in this respect. However, detailed information on bark absorption is currently very scarce.

Repeated measures of decaying wood reveal the success and influence of fungal wood endophytes [PDF]
Predicting wood decomposition is challenging due to complex successional dynamics among decomposers that colonize and defend wood territory. This starts with saprotrophic fungi that reside latently in healthy wood until trees senesce, but these ...

Sound Attenuation Devices for Dogs Barking (Estimation of Aperture Ratio and Experimental Study of Silencer) [PDF]
This paper reports a natural ventilation silencer for an animal cage having considerable sound insertion loss. Many veterinary hospitals face a serious problem that hospitalized animals are stressed from the barks of other dogs in the hospital. To address this problem, a solution that barely affects caged dogs’ health is required.
