The Church building secularization through its sound Sound in a contemporary case study
* Presenting author
Acoustics in a contemporary liturgical place, particularly in a catholic context, is far from obvious. This work describes some main indications for the design of new churches, starting from the project of Sant'Ambrogio Church in Trezzano, Milan (IT). The article presents room acoustics procedures, results, discussions, theoretical interpretations of the sound propagation in the specified space, and the implementation of computer simulation techniques, emphasizing the continuity and breaking elements with the historical churches.In the past the sacred sense in a church was linked to emphatic rites and to the attainment of transcendent states. This effect had to be greatly reinforced by the surrounding atmosphere created in very reverberant spaces and possible echoes that infatuated the perception of God and his presence. On the contrary, nowadays concentration and intimacy are preferred, the reverberation time is reduced, increasing the speech intelligibility of the homily to understand the message of God, while music or songs steel accompany the choral word of church goers.The proposed acoustic design includes a new approach with an acoustic response suitable for both speech and music, considering also the recent room acoustics studies in other typologies of building such as congress centers and multipurpose auditoria.
