Abstract
Due to the extinction of some wood species used to manufacture guitars, there is a trend to search new alternative materials with the same acoustic performance. There is a wide range of tonewoods: ebony, rosewood, yellow and red cedar, mongoy and sapelli, among others. These woods have high resonance qualities and the requirements are both acoustical and mechanical. In this work, alternative composite materials have been manufactured to compare dynamic and psychoacoustic parameters with the commonly used woods. This comparison will allow to conclude the possibility of using these materials as substitutive of tonewoods.
Highlights
Deforestation in some parts of the planet is becoming a threat for the use of some woods in musical instruments, specially the tropical species
Other authors focus their investigation on alternative materials to wood ([3][4])
The goals of the investigation are: - To compare the results of the FFT. - To compare the psychoacoustic parameters
Summary
Deforestation in some parts of the planet is becoming a threat for the use of some woods in musical instruments, specially the tropical species. The current situation makes a need of substituting these materials for these applications. Some researchers focus their works on other types of wood [1] [2]. The vibroacoustic parameters of biodegradable materials, as substitutive of woods, are studied. Other authors focus their investigation on alternative materials to wood ([3][4]). With these materials, the goals of the investigation are: - To compare the results of the FFT. The results will allow to evaluate the possibilities of using these alternative materials
