APPLICATION OF HIGH-FREQUENCY DENSITOMETRY TO DETECT THE CHANGE OF EARLY- AND LATEWOOD DENSITY OF OAK (QUERCUS ROBUR L.) DUE TO THERMAL TREATMENT

The heat treatment of wood is an environmentally friendly method for wood protection. The progressive thermal degradation of the wood components at process-temperatures above 180°C leads to the reduction of …

Comparative durability tests on TMT beech – preliminary results

The natural durability of wood refers to the resistance to attacks by wood-destroying organisms, e.g. fungi, insects and marine organisms. In this study the durability of thermally modified timber (TMT) …

Using wood as display case material for museums – an aproach for the production of low-emission wood

Wood as a natural material contains volatile organic compounds (VOCs) like formaldehyde and carboxylic acids. For this reason, wood is not suitable for applications in contact with precious and heavy …

Frequency-response-determination of tonewood as an alternative to modal analysis

For instruments like Guitars or Violins, special tonewoods are required to achieve the desired sound. In order to determine the acoustic properties of such tonewoods, instrument makers and merchants of …

Acoustical comparison of a TMT guitar and a tropical wood guitar using the frequency response analysis

To this day almost all guitar makers worldwide primarily use tropical wood like palisander (Dalbergia spp.) for their manufacturing. Due to the current CITES regulation from January 2017 related to …

Products made of thermally modified timber and tested especialy for applcations in asiatic countries

This research-project focused on the production and performance characterisation of thermally modified timber, especially used for applications in countries with tropical, subtropical or desert climatic zones (Middle East, Asia). In …

Sound absorption coefficient of thermally modified and unmodified wood species measured in an Impedance Tube

Different parts of the guitar body are made of certain wood species, selected by their specific properties. The sound board, which is mainly made of spruce or cedar, transfers the …

Comparison of different recipes for thermal modification of European tone wood and their influence on the acoustic behaviour

Until today, a variety of instruments are made of wood. Especially in the field of string instruments, wood is the material of choice, due to its good resonance qualities. The …

Application of chemical buffers to prevent and reduce VOC-emissions of different wood-species

In museums the installation of wooden display cabinets is prohibited due to the VOC’s and their corrosive effects on metals -especially lead. Regularly all materials have to pass the obligatory …
