PEAQ(PerceptualEvaluation ofAudioQuality) is a standardized algorithm for objectively measuring perceivedaudio quality, developed in 1994-1998 by a joint venture of experts within Task Group 6Q of the International Telecommunication Union's Radiocommunication Sector (ITU-R). It was originally released as...
;;; 1994年,ITU要求几家机构研究出可用于竞争比较的解决方案来衡量编解码器的音频性能。这些方法最终合成为一个方法称为PEAQ(Perceptual Evaluationof Audio Quality,可感知音频质量评价),并于1998年作为《ITU-R建议书BS. 1387-可感知音频质量客观测量方法》[13发表。尽管其主要针对编解码器,但是此文件所提出的听觉...
PEAQ,一项由威斯康辛-麦迪逊大学的农学家Ken Albrecht和Rod Hintz共同提出的科学方法,旨在评估田间苜蓿的质量。他们发现,在田间生长的苜蓿中,非结构性氮化物(NDF)和酸洗涤纤维(ADF)的含量可以通过特定的测量手段来预测。这个过程包括在具有代表性的样方中测量最长茎秆植株的茎长,同时对样方中最成熟的...
PEAQ (Perceptual Evaluation of Audio Quality) is a standardized algorithm for the objective measurement of perceived audio quality. It predicts the perceived audio quality of mono and stereo audio files as listeners would do in a subjective listening test according to ITU-R BS.1116-1. ...
当使用PEAQ法预测时,建议在RFV的实际值比预期值高出15-20%时,考虑开始收获。另外,PEAQ法对植株高度有特定的要求,预测的准确性依赖于这一条件。如果苜蓿植株的高度低于40.6厘米或高于101.6厘米,那么其预测结果可能存在偏差。因此,在使用PEAQ法进行评估时,务必确保苜蓿植株处于适宜的生长阶段。

在进行PEAQ测定时,首先在苜蓿田中选择一个具有代表性的0.2平方米样方,这个样方需要反映出田间的整体状况。接下来,依据表中的标准,识别出样方中最成熟的茎秆,并以此判断其生长阶段。判断标准是根据茎秆的生长状态而非叶片的高度来确定。然后,寻找样方中最长的茎秆,测量其从土壤表面到茎尖的长度。确保...
