摘要
依托EN 50332标准,基于实际项目测试经验,对耳机类产品最大声压级测试过程中容易产生测试差异的四个因素,包括测试信号、头和躯干模拟器、耳机佩戴、自由场/扩散场响应修正,描述了标准要求、分析了问题并提出了改善建议,这有利于降低不同检测机构间的测试差异,保证耳机产品在不同地域正常销售。
Based on EN 50332 and headphones ＆ earphones project experience, the four factors that can cause test difference are analyzed, including test signal, head and torso simulator, fit, and free field/diffuse field response modification. Describes standard requirement, analyzes problems and puts up suggestion for improvement. This work will help minimize the test difference between different test agencies, and guarantee product sales among different areas .
