ACOUSTIC ANALYSIS OF THE ST. MARK'S BASILICA IN VENICE BY MEANS OF QUADRAPHONIC IMPULSE RESPONSE MEASUREMENTS

A measurement campaign inside the Basilica di San Marco in Venice has been conducted with the purpose of characterizing the acoustical properties of some source-receiver configurations which are of interest from the historical point of view. Measurements of quadraphonic impulse responses (including sound pressure and three components of particle velocity vector) have been done with the purpose of studying the relationship between standard room acoustics indices as clarity and reverberation with the behaviour of energetic quantities.
