Abstract

Material selection systems and methods for constructing a musical instrument and/or where a selected material is a wood material are disclosed. One example material selection system includes a rating module and a rating database. The rating module includes an excitation device configured to act upon material samples; a vibration receiver in cooperation with the excitation device; a rating computer coupled to the vibration receiver, the rating computer configured to execute stored instructions for determining a set of material sample ratings based on FFT analysis of data collected by the vibration receiver; and an output device operatively coupled to the rating computer, the output device configured to output the determined set of material sample ratings to a rating database. Each set of material sample ratings is associated with a material sample. Another example material selection system may further include a selection module with a selection computer coupled to the rating database.

Dependent claims

A material selection system for constructing a musical instrument and/or wherein a selected material is a wood material, comprising:

a rating module comprising:
an excitation device configured to act upon each of a plurality of material samples,
a vibration receiver in cooperation with the excitation device,
a rating computer coupled to the vibration receiver, the rating computer configured to execute stored instructions for determining a set of material sample ratings based on Fast Fourier Transform (FFT) analysis of data collected by the vibration receiver, the rating computer determining one or more modal frequencies for one or more respective frequency modes of the material samples based on the FFT analysis of data, the rating computer further determining one or more of the material sample ratings by:
(i) establishing a hypothetical best value for a particular material parameter, (ii) scaling the hypothetical best value for the particular material parameter to a base number, and then (iii) scaling an actual material parameter value for the particular material parameter to the base number, the particular material parameter being computed as a function of the one or more modal frequencies determined by the FFT analysis of data;
and
an output device operatively coupled to the rating computer, the output device configured to output the determined set of material sample ratings;
a rating database configured to receive and store a plurality of sets of material sample ratings, each set of material sample ratings associated with a material sample;
and
a selection module comprising:
a selection computer coupled to the database, the selection computer configured to execute stored instructions for selecting a specific material sample based on user-preferred material characteristics, and
a user interface configured to:
receive the user-preferred material characteristics;
and
transmit an identification of the selected specific material sample.
