Relationship between density and aesthetic attributes of wood and preference of Malagasy consumers

How do consumers express their appreciation of wood surfaces? Norway spruce floors in Germany as an example

“…Future work might consider the comparison of differently coloured species while examining appreciation and preferences among consumers. Ramananantoandro et al (2013) measured colour (CIEL*a*b*), texture and density and revealed preferences for darker and yellowish wood surfaces among Antananarivo consumers in the case of a range of 12 species with yellow to red, light to dark, textured and non-textured surfaces used for furniture.…”

Wood machining with a focus on French research in the last 50 years

“…These defects are in direct relation to surface functionality (De Moura 2006). In order to assess the quality of a wood machined surface, two sets of criteria are generally used: those linked to geometry and those related to the physics and chemistry of the surface (Gurau 2007;Rajemison 2013).…”

“…Commonly-used criteria defined in the standard are raised grain, fuzzy grain, torn grain and chip marks (Goli 2003). Some authors have also used machining traces and splinter occurrence at the end of the wooden piece (Khazaeian 2006;Rajemison 2013). The disadvantage of this surface assessment comes from its subjectivity, because it is fully dependent on the assessor's perception (Marchal and Mothe 1994;Scholz et al 2007).…”

“…The direction of measurement has a significant influence on the results obtained for wood (Sinn et al 2009). A new available standard (ISO 25178-2 2012) allows these criteria to be defined in three dimensions (Ramananantoandro et al 2013). However, if the difficulties related to wood anisotropy are solved with contactless devices, 3D surface roughness criteria and the use of a minimum sensing surface (Larricq et al 2000), the problems related to signal filtering remain (Gurau et al 2009).…”

Consumers’ perceptions and preference profiles for wood surfaces tested with pairwise comparison in Germany

“…As found by Marchal and Mothe (1994) in France, diverging preferences could be identified where one group preferred clear surfaces and another group preferred slightly knotty surfaces (small knots). From a preference study of Malagasy consumers, Ramananantoandro et al (2013) conclude that aesthetic features like colour and texture and the density of furniture wood species have an effect on consumers' preferences. Hoibo and Nyrud (2010) suppose harmonious and homogeneous surfaces are preferred by consumers which are achieved with few knots and even knot patterns in visual product surfaces.…”
