This study examines the fricative property that characterizes a group of sounds in Arabic. This property refers to the friction of air through the organs that produce the fricative sound, due to the weak dependence on the point of articulation and the lack of precision. Through this study, the researcher will attempt to monitor the variation in the acquisition of this property by sounds and establish a sound sequence for them, based on data from the vibrational and spectral physics study. An audio sample of fricative sounds from the Holy Quran was obtained and processed using Pratt and Adobe Audition to monitor the energy of these sounds, the value of their vibrational oscillations, the value of their pitch, and the length of time required to pronounce them. The experimental study concluded that the time required to pronounce the "ha" sound was the longest of all fricative sounds, reaching 0.451. This can be explained by the wideness of the vocal tract for this sound, indicating a relationship between the wideness of the vocal tract and the length of time required to pronounce the sound, due to the weak friction at the point of articulation. While the time taken to pronounce the letter “tha” was the shortest, reaching (0.131). The voiced fricatives (ghain, dha, thal, zay) had more energy than the voiceless fricatives, and the lowest energy was the sounds of fa and tha.
