Resumen
As in most European countries, Portugal has a long and rich history of performing arts, mainly centred on music and drama. Evidence of spaces for arts performance were found in Lisbon, in 1798, in the form of roman theatre ruins dating back to the 1st century A.D. However, it was only during the 18th century that the first Opera Houses were built in Portugal, some of them surviving almost intact and operational until today. Until the end of the 20th century more than 150 theatres and concert halls were active, a number that has been surpassed with modern buildings constructed in the last 6 years. With the continuous increase in the search for music, opera, dance and theatre performances spreading over the whole country, the need for an acoustical perspective on this patrimonial legacy was obvious. In this report we present a summary of the first thorough acoustical survey of the 33 most important theatres and concert halls distributed over 16 cities from the North to the South of Portugal. The results of measurements of reverberation time and other acoustical parameters for various source and receiver positions are presented.
