Experience shows the occurrence of situations when the measurements of impulse noise parameters are made with measurement equipment unsuitable for such conditions. The results of using such equipment were compared with the results of using equipment with a sufficiently large upper limit of the measurement range. The analysis was carried out on the example of noise generated during shots from a Mossberg smooth-bore shotgun and AKM rifle, as well as produced in the forge. The use of the unsuitable equipment allowed to indicate the exceeding of the exposure limit value of the peak value of the signal (), but this is not always possible when determining the energy properties of the signal (). While the inadequate properties of the measurement equipment will generally not prevent the conclusion that noise in a particular workplace is hazardous to hearing, the results of measurements cannot be used to select hearing protectors.
经验表明，存在使用不适用于此类条件的测量设备来测量脉冲噪声参数的情况。将使用此类设备的结果与使用测量范围上限足够大的设备的结果进行了比较。以莫斯伯格滑膛霰弹枪和AKM步枪射击时产生的噪声以及锻造过程中产生的噪声为例进行了分析。使用不合适的设备能够显示信号峰值的暴露极限值超标（），但在确定信号的能量特性时（）并非总是可行。虽然测量设备性能不足通常不会妨碍得出特定工作场所的噪声对听力有害的结论，但测量结果不能用于选择听力保护器。
