摘要
对助听器检测通常采用的国家标准为GB/T 14199-2010电声学助听器通用规范和GB/T25102.100-2010电声学助听器第0部分:电声特性的测量,检测中需要关注的量值有频率范围、频率点、声压级、最大声压级、声压级均值、声压增益均值、谐波失真值、电流值,本文对此进行了分析总结,理顺了检测中相关量值的关系。
National standards for the detection of hearing aids commonly used to GB / T 14199-2010 General specification electric acoustic hearing aids and GB / T 25102.100-2010 electric acoustic hearing aids - Part 0： Measurement, Detection need to focus on the magnitude of the electro-acoustic characteristics have frequency range, frequency, SPL, maximum SPL, SPL mean, mean sound pressure gain, harmonic distortion value, the current value of this were analyzed and summarized in this article, to rationalize the magnitude of the correlation detection relationships.
