Impulse response measurements using log sine sweeps were made in the Warsaw’s Chamber Opera House in eight microphone locations on the floor area and at two locations on the balcony, with two microphone elevations, using two types of sound sources having different directional radiation characteristics. The Opera House having only 159 seats originates from 1775 and is renowned for its excellent acoustics fitting for Mozart operas. The measurements show how within this relatively small venue, an opera director can create a wide range of acoustic perspectives for voices and instruments, and achieve a desired dramatic effect. In a subsequent multichannel auralization, anechoic instrumental and vocal sounds were placed virtually in the opera house, and a listening panel compared the renderings. The experiment underlines the importance of choosing directional characteristics of sound sources used in the measurements of room impulse responses intended for subsequent applications.
