Although a vineyard hall has both acoustical and architectural merits associated with its short source-receiver distance, attention to acoustical design needs to be placed upon the terrace seating that primarily governs the energy distribution in such a hall, in particular when listening to the vocal sound where both acoustic and visual deprivation exists. Design schemes were developed sequentially with an emphasis on seating division and evaluated by computer modeling using Odeon 9.2 acoustic software for a hall with approximately 1/4 of the seats surrounding the stage. The effect of solo singing was evaluations by listeners representing musicians and the general public based on pair comparison. Anechoic soprano and baritone singing segments with calibration information were recorded. Side terraces, preferably stepped back or splayed toward both ends of the hall, are essential for controlling the overall energy distribution. 3-dB high-frequency energy compensation can be provided for the terrace seats su... |
