ANSI/ASA S3.6-2010 听度计规范

The audiometers covered in this specification are devices designed for use in determining the hearing threshold level of an individual in comparison with a chosen standard reference threshold level. This standard provides specifications and tolerances for pure tone, speech, and masking signals and describes the minimum test capabilities of different types of audiometers.

MH/T 9003-2008 电声学.航空噪声测量仪器在运输类飞机噪声合格审定中测量1/3宽带倍频声压级装置的性能要求

为了进行飞机噪声适航审定，本标准规定了用于测量噪声的仪表系统的电声性能要求，还推荐了一些对仪器系统进行定期测试的方法，以检验设备的性能是否持续符合规定的容限要求。 一般地，一个噪声测量系统是由一系列仪器所组成的，包括传声器、记录仪、分析仪以及输出设备等。实际应用的测量系统的组成不完全一样，但是都能够以不同的方式实现所需要的功能。系统可以是模拟的，也可以是数字的。 本标准的目的是为了在规定的基准环境条件下，在规定的容限范围内，保证不同的测量系统有相同的电声特性。本标准并不提供关于安装传声器或传声器防风罩的方法 , 也不提供用于飞机噪声适航审定的有关测量和分析程序要求，而仅提供用于获得在一段时间内平均的1/3倍频带声压级测量系统的性能规范。 有些要求适用于整个测量系统，包括在分析前记录所测量的声压时间信号的方法。有些要求适用于传声器，传声器用于把所测量的声压信号转化成电信号。另外，还有些要求仅适用于分析仪，分析仪用于把信号转化成1/3倍频带声压级输出。 本标准的要求适用于测量噪声的仪表，所测噪声是由最大审定起飞重量大于900Okg的喷气式或螺旋桨驱动运输类飞机产生的，或是由安装在户外发动机试车台上的推进系统产生的。

The purpose of this practice is to enable the transfer of calibration from sensors that have been calibrated by primary calibration to other sensors.1.1 This practice covers requirements for the secondary calibration of acoustic emission (AE) sensors. The secondary calibration yields the frequency response of a sensor to waves of the type normally encountered in acoustic emission work. The source producing the signal used for the calibration is mounted on the same surface of the test block as the sensor under testing (SUT). Rayleigh waves are dominant under these conditions; the calibration results represent primarily the sensor''s sensitivity to Rayleigh waves. The sensitivity of the sensor is determined for excitation within the range of 100 kHz to 1 MHz. Sensitivity values are usually determined at frequencies approximately 10 kHz apart. The units of the calibration are volts per unit of mechanical input (displacement, velocity, or acceleration). 1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
