The objective of this article is to study the existing relationship between training and the integration of Sustainable Development (SD) practices in the Moroccan University. The issue at stake is to verify whether the training provided at the level of higher education institutions responds to the various worldwide challenges. In order to respond to the difficulties that impact the higher education model, Moroccan universities are invited to rethink their various approaches so that they can respond to the economic, social, societal and environmental constraints which are constantly evolving. Therefore, these universities must align themselves with the major challenges facing education today[1]. The empirical research method used in this quantitative study is a Likert’s scale based questionnaire. The investigation was carried out on a sample of 134 teachers-researchers of Ibn Tofail University of Kénitra (ITUK) (Morocco). The investigated sample population was surveyed during the time period lasting from February the 1st to May the 31th, 2021. The analysis conducted regarding the results of the ANOVA of the variables reveals that the pedagogical approaches, curriculum and teaching methods are significant except for the teaching activities which display a value of 0.280 higher than the recommended threshold. Consequently, training in higher education can contribute to forging attitudes in the future in line with SD’s requirements by relying on pedagogical approaches. Hence, the University through training should contribute to a sustainable society in order to meet the 17 SD Goals which require that by 2030 all students should have the knowledge, skills and attitudes necessary to promote sustainable development. The results of this research will contribute to the development of new training curricula that meet the requirements of the various SD objectives. We have focused our research on the ITU Kénitra, we believe that our approach will serve as a basis to develop other cases of Moroccan universities to have an overall vision of training curricula converging towards the practices of SD at the Moroccan national level and for a better contribution in the new 2035 nationwide development model[2].

In this work, sound pressure levels of road traffic on about twenty selected locations in the Agdal District in Rabat City were carried out. The traffic consists mainly of light vehicles with similar characteristics. All measurements were performed in 1/3 octave with an integration step of 20 ms during the period of 15 days from 8 a.m. to 7 p.m. This large amount of data allowed the reconstruction of the spectrograms using a script written in Mathematica language. An interesting result obtained concerns the basic interval required to have a sufficiently representative equivalent level. Indeed, the calculations have shown that about 20 min of measurements are sufficient. This confirms the result already mentioned in our previous work. This result will therefore make it possible to optimize the measurement period during the campaign, in particular for locations where the number of locations is high or the quantity of recordings is large. Frequency analysis revealed spectrum similarities between two locations of different traffic intensities, but of similar composition. This observation is also observed over the different periods of the day (morning, afternoon, evening). In addition, an estimate of the inconvenience felt by local residents was made on the basis of the L den estimated from the measured L 50 . It emerges that, for the majority of the locations subject to the measurements, the percentages of very inconvenienced and inconvenienced people are above 20% and 30% respectively. This result corroborates the results of our previous survey.

The use of absorbent materials such as fibrous materials is considered as an innovative solution to solve noise problems. The purpose of this research paper is to study the acoustic absorption of a new bio-sourced fibrous material called "Alfa fibers", in order to use it as an absorbent material to reduce reverberation time in the building construction domain (theatre, cinema, conference room, ...). For that, a set of 36 samples was designed and prepared for different thicknesses and different densities in order to evaluate the effect of thickness variation and density variation on sound absorption performance. An experimental study was carried out to measure the sound absorption coefficient at normal incidence, using the ISO 10534-2 standard method known as two-microphone transfer function method. All tests were performed in a Kundt tube with a diameter of 10 cm, in the frequency range (50-1600 Hz). These measurements show that the absorption coefficient can reach a value of 0.9 around 1000 Hz. The experimental results clearly show that sound absorption improves when the thickness of the samples increases, or when the density increases to an optimal value of 300Kg/m3 from which absorption performance begins to decrease. At low frequencies, sound absorption can be improved by creating an air gap between the sample and the rigid bottom.
