Abstract

The application of sound field control to outdoor live events at low frequencies is a recent one due to increased concerns regarding noise pollution and stronger regulations. Here is presented an overview of the techniques being recently investigated based on model, data or hybrid approaches. The approaches presented here provide encouraging results but they all deal with the problem at relatively short distances (approximately 100 m). Translating these results to larger distances is going to be a challenge as a new set of problems needs to be addressed. An overview of the most relevant issues encountered in long range applications such as uneven terrain, properties of the medium, ground and obstacles interactions is also presented.
