The term 'good acoustics' can be applied in a number of different ways, with different meanings. Generally it means a balanced united action between reverberation time, background noise and sound insulation. In a room with good acoustics the required sound is emphasised, while unwanted sounds are eliminated or reduced sufficiently so as not to cause a disturbance.
