Airborne Sound<\/a> From Outside <\/strong>– These are sounds that have been transmitted through the air,\u00a0roof and walls. Anything from traffic noise to ambient noise needs to be isolated away from the\u00a0concert hall so that the softest passages will not be masked. In the past, large and thick walls have been built to do this, but in modern times, layered walls with decoupling and insulation have been used to attenuate airborne sound as much as possible.<\/p>\nStructure-borne Sound <\/strong>– Sound travels much faster in a medium, when there is something that\u00a0directly vibrates against a structure that is joined to the the concert hall. Traffic and trains are\u00a0sources of structure-borne sound through the ground. To resolve this, the walls need to be\u00a0decoupled from the floor surround the concert hall via springs or pads.<\/p>\nBackground Noise <\/strong>– There could be machinery inside the concert hall that could add to the\u00a0background noise level, such as air conditioning units and lighting equipment. Steps could be\u00a0taken to insulate the air ducts and vibrating equipment to be floated on springs.<\/p>\n <\/p>\n
Music or Speech?<\/strong><\/h2>\nThe design of a performance venue is highly dependant on what application it is used for. A\u00a0performance venue attempting to be a jack of all trades will likely result in compromises for each\u00a0application, as the adage goes – a master of none. One of the key things to decide for a concert\u00a0hall is – Reverberation Time.<\/p>\n
