Building on hall acoustics design features and tools reviewed Write papers network: Abstract: As the listening place, hall building is the first important listening quality. For living room design features and architectural acoustics by means of brief. Keywords: hall construction, acoustics, designed as listening venues. Hall building listening quality is the first important architectural acoustics must be carefully designed to do, to ensure its quality and only the main points of clear architectural acoustics design and methods in order to hall building to ensure good sound quality. First, the main points of general building acoustics design, architectural acoustic design elements including noise control and acoustical design of two parts. (A) noise control is usually concert halls, theaters and other indoor halls require a very low background noise, so the location of these halls is very important as far as possible away from the outdoor noise and vibration sources. Also, the site environment noise and vibration survey, measurement and simulation forecasts, for the purpose hall for sound insulation of building envelope design basis. to ensure that the hall is completed to achieve the desired indoor noise standards, In addition, architectural acoustic design, another important task is to carry out Interior sound design. (B) the sound design sound design work typically includes the following contents: 1 to determine the size and body mass halls. (2) to determine the quality indicators and their optimal design values ??based on the use of feature selection hall reverberation time, clarity, strength index, lateral energy factor, binaural cross-correlation coefficient and other quality evaluation, and to determine the optimal value of each index, sound design is an important task. 3 for orchestra, band stand, box, balcony and hall acoustic design of the interface. 4 calculation of auditorium acoustics parameters. When the hall
