GB/T 33723-2017 in English

GB/T 33723—2017 Standard Overview

GB/T 33723—2017 "Standard for the Grading of Subjective Evaluators of the Acoustic Quality of Musical Instruments" is an important standard in China's musical instrument industry, which aims to provide standardized guidance for the subjective evaluation of the acoustic quality of musical instruments. This standard is under the jurisdiction of the National Technical Committee for the Standardization of Musical Instruments, covering the professional qualifications and skill requirements of evaluators and the organization and management of the evaluation team.

Background and Significance of Standard Formulation

With the development of the music industry, the objectivity and consistency of the acoustic quality of musical instruments have become the focus of the industry. The formulation of this standard fills the gap in the field of subjective evaluation and ensures the scientificity and fairness of the evaluation process. By standardizing the requirements for evaluators, it will help to improve the overall quality level of the musical instrument industry.

Technology Evolution Analysis

GB/T 33723-2017, based on the previous standards, introduced stricter hearing sensitivity requirements (125Hz~8000Hz frequency band hearing threshold level is lower than 20dBHL) and higher evaluation skills threshold. At the same time, this standard complements GB/T 31109-2014 and together they build a complete musical instrument acoustic quality evaluation system.
