HB 6167.15-2014 in English

本部分规定了民用飞机机载设备耐声试验条件和试验方法。本部分规定的条件适用于设备在研制、生产阶段进行耐声功能试验；也适用于在设备研制过程中为发现结构缺陷进行的耐声持久试验。
本部分适用于对声振敏感的设备，有关标准应规定进行耐声功能试验和耐声持久试验的必要性，使用宽带噪声或是谐波噪声以及适用的试验声压级。本部分不适用于在飞机上所处区域的总声压级小于125 dB的设备。

Scope

This part specifies the sound resistance test conditions and test methods for civil aircraft airborne equipment. The conditions specified in this section are applicable to the sound resistance functional test of the equipment during the development and production stages; they are also applicable to the sound resistance endurance test to detect structural defects during the equipment development process. This section applies to equipment that is sensitive to sound vibrations. Relevant standards should stipulate the necessity of sound resistance functional tests and sound resistance endurance tests, the use of broadband noise or harmonic noise and applicable test sound pressure levels. This section does not apply to equipment located on an aircraft where the total sound pressure level is less than 125dB.
