GB/T 25102.7-2017 Electroacoustics—Hearing aids—Part 7:Measurement of the performance characteristics of hearing aids for production, supply and delivery quality assurance purposes
Abstract
This part of GB/T 25102 specifies the performance characteristics measurements and performance requirements for hearing aids produced, supplied, and delivered for quality assurance purposes. Manufacturers typically provide nominal values. Only when the measurement results fall within the expanded uncertainty range specified in this part and fully comply with the tolerances set forth herein, can they be deemed consistent with the specifications of this part. Table 4 provides the expanded Umax values. This part applies to specific types of air-conduction hearing aids. This part does not cover mechanical or environmental testing. Generally, it should not be used as a basis for comparing the performance characteristics of hearing aids, nor should it be used as a predictive value for real-ear performance.
