Multi-Channel Orchestral Anechoic Recordings for Auralizations
Multi-channel orchestral anechoic recordings were obtained at the Technical University of Denmark (DTU) in June 2005. Every orchestral part of specific movements of two symphonies, Brahms’ Symphony No. 4, 3rd movement, and Mozart’s Symphony No. 40 in g minor, 1st movement, were digitally recorded using five 0.5” DPA microphones, with four surrounding the musicians in […]
Integrated Room Acoustics and Electro Acoustic Design – the Concert Venue at Rockheim, Norway
There is a significant potential in ensuring a high degree of interaction between room acoustic and electroacoustic design, especially for concert venues optimized for amplified music. This paper will address key room acoustic criteria for venues for pop and rock music. Also, the interaction between the room acoustic and electroacoustic design through the different design […]
On the Struggle to find a set of Room Acoustical Parameters that Explains and Predicts Subjective Ranking of Concert Halls
During the 20th century a huge number of room acoustical parameters to describe concert hall acoustics were suggested. Too many, in the opinion of acousticians, who by the beginning of millennium arrived at some consensus expressed by the proposed set of five parameters now found in ISO 3382. One should expect that this quintet would […]
The Room Acoustic design of the Guangzhou Opera House
The 1800 seat Guangzhou Opera House designed by Zaha Hadid Architects opened formally in February 2011. The design of the interior of the performance hall was completed with input from Marshall Day Acoustics (MDA). This paper follows the design process for the Opera House interior from the discussions of the initial design concepts and the […]
The Acoustics Requirements of the Irish Chamber Orchestra
The Irish Chamber Orchestra (ICO) is considered by many to be the premier ensemble in Ireland and one of the finest Chamber Orchestras in the world. This reputation has kept the orchestra in high demand, both nationally and internationally, and has helped the orchestra to attract world class musicians. The experience these musicians have of […]
An Impedance Model for Estimating the Complex Pressure Reflection Factor
One of the limitations in room acoustic computer modelling is the characterisation of the reflecting surfaces by the sound absorption coefficient. Especially at low frequencies, say below 500 Hz, the phase of the reflections may be important for accurate simulations of the room impulse response. In order to allow the inclusion of the phase of […]
