Problems solved by technology

Traditional musical instrument acoustic evaluation needs to be carried out in a professional acoustic laboratory. Players are required to play viola music, and judges sitting in different positions in the acoustic laboratory make evaluations. It can be seen that there are human factors in the evaluation

Abstract

The invention discloses an acoustic evaluation method and experimental device of a viola resonance box based on impedance technology, and is characterized in that: the experimental device includes an impedance analyzer, a viola resonance box, a first piezoelectric sensor, and a second piezoelectric sensor , the 3rd piezoelectric sensor, the 4th piezoelectric sensor, computer and software processing system thereof, test experiment device and evaluation method of the present invention, do not need the player to play the viola, directly use the impedance analyzer to viola resonance box in alto-1 Zone, Alto Zone 2, Treble Zone 1, and Treble Zone 2 are scanned to test the impedance spectrum of the viola resonance box within the scanning frequency range, and then judge the viola resonance box according to the impedance spectrum of the viola resonance box. Pros and cons. The invention has simple structure and reasonable design, overcomes the artificial factors in evaluating the timbre of the viola in the traditional method, objectively evaluates the timbre of the viola resonance box, and provides a brand-new viola evaluation method for viola manufacturers.

Description

technical field [0001] The invention relates to the fields of impedance technology and viola production technology, in particular to an acoustic evaluation method and experimental device of a viola resonance box based on impedance technology. Background technique [0002] First of all, the viola resonance box is one of the key components of the viola. The resonance box is the pronunciation amplifier of the viola, and it is an important component related to the volume and tone of the viola. The quality of the viola resonance box is directly related to the quality of the viola. The resonance box of the viola is mainly composed of a panel, a bottom plate, a side plate, an f-shaped sound hole, a sound column, and a bass beam. In the vibration of the viola, the vibration energy from the strings is transmitted to the piano board, the body and the nearly closed resonance box through the bridge, and the sound waves are transmitted through the resonance box. There are not only the ...
