After contacting the venue in advance and informing them about the process and importance of Impulse Response Measurements, my team and I visited York’s Grand Opera House on Wednesday the 27th of February. Our aim was to move across all 3 floors of the opera house and changing each time the location of the source or receiving position. The process for obtaining the impulse responses was the same as mentioned in the previous BLOG, by using two Genelec loudspeakers and a Soundfield ST450 microphone. The two sources recorded were located in the center of the Stage as well as the center of the Orchestra Pit. The receiving positions were all across the sitting area of the venue, spreading in all 3 floors including on of the boxes in the side.
