This plaza, made with small mosaic pieces, covers an area full of different colors measuring 32,000 square meters. The central feature of this Park is a large mural plaza, 80 x 400 meters, made by the plastic artist Byron Gálvez, who comes from Hidalgo. The idea came about in this project to create a 25-hectare Cultural Park with the name “Parque Cultural y Recreativo David Ben Gurion”. Ejido societies, government entities and private promoters formed a partnership to make viable the construction of this Cultural and Services Complex. The simulated results confirm the appropriateness of the choice of the new seating for the refurbishment of the concert hall.In the City of Pachuca, in the State of Hidalgo, Mexico, a new urban development was created, consisting of various residential, commercial and services programs in a section of the City known as the “Zona Plateada”1 (Silver Zone). Likewise, the acoustic effect of an already executed seating replacement in the performance space is analyzed in relation to the degree of occupancy of the room. The influence of the degree of detail of the geometric model on the outcome is also considered by incorporating the 44 iconic lamps specifically designed for this enclosure, into the model. The model is validated by comparing simulated and measured figures for the most significant monaural and binaural room acoustic parameters assessed at multiple locations both on the stage and within the audience areas, then by performing both spectral and spatial analyses of their behaviour, and ultimately studying dissimilarities between the two sets of data in terms of just noticeable difference (JND). The 3D geometrical acoustic model created for this purpose is tuned by adjusting the absorption and scattering coefficients of the convex reflector ceiling of the auditorium through an iterative process aimed at rendering differences between simulated and measured values for reverberation time in each octave frequency band lower than 5%. This paper presents the results of the acoustic simulation of the Manuel de Falla Auditorium (MFA), Granada, Spain, carried out in CATT-Acoustic and CATT–TUCT.
