Mainly reverberation and echo

The concert hall is the main place for the band to perform. Besides the concert hall dedicated to the band, the opera house, the great hall, the cathedral, the studio hall and the cinema can all be used as concert halls.

reverberation is the main factor reflecting the quality of concert hall. After the instrument stops pronouncing, the sound does not disappear immediately, but is accompanied by reverberation, that is, the decibel number gradually decreases. This phenomenon is called reverberation, and the time when the sound decays by 6dB is called reverberation time in acoustics. Reverberation is a

concert hall, which is caused by the reflection of sound indoors. It is a place where concerts and music-related activities are held and people feel the charm of music. It is usually composed of a concert hall and a small theater, with elegant decoration and appropriate layout.

There are many factors to consider in concert hall design, including the pursuit of bright light and reasonable illumination. The world-famous concert halls include Vienna Concert Hall, Sydney Opera House and national centre for the performing arts. At the same time, many concert halls are local symbols.

Among all the expressive elements of music art, synaesthesia is the expressive element related to color. The phenomenon of visual-auditory synesthesia is mainly manifested in pitch and tonal color, timbre color and harmony color. Tonality color is one of the most popular topics for composers. It is found that the color sense of bars may be related to the number of ascending and descending signs. In addition, the timbre of musical instruments is often described by color. For example, the oboe is green, the flute is silver or blue, the trumpet is golden yellow and the clarinet is rose. Chords are more related to brightness: major chords are bright and minor chords are gloomy.

Sometimes chords are combined with movement: adding a triad is a deep breath-like feeling of expansion, while subtracting a triad is curled up. Therefore, whether the color selection inside the concert hall is correct or not is an important link in the whole concert hall design process, which is related to factors such as intimacy, warmth and space, and will directly affect the subjective feelings of the audience.
