Abstract
The quality of sound reproduction in living spaces are determined by the attributes of the loudspeaker, and the acoustic qualities of the reproduction space. This is also true for the special case of television set reproduction. In order to improve reproduction quality, the ability to predict the acoustic response of a television set in specific room environments is advantageous. In this work, a combined finite element/geometric acoustic simulation regime is prepared and specialised for television set installations. A television set is characterised as an acoustic source based on a set of anechoic measurements. Typical television set installation conditions can be problematic for conventional transparent source models, and so a counter strategy is proposed to improve a classic image source model by additionally utilising semi-anechoic measurements. The simulation techniques are evaluated by comparing simulated with measured in-room responses for a characterised television set source in wall-mount and table-top installation conditions with a conventional loudspeaker source reference case.
