There are many pinholes on the walls around the concert hall to reduce the reflection of sound waves. Sound will also be scattered on uneven reflecting surfaces, and the scattered sound waves will cross each other, causing each other to consume energy. As a result, the scattered sound cannot reach the energy of the echo, which will weaken the reflection of the sound. Theaters and concert halls are surrounded by uneven, honeycomb-like walls, which can reduce the reflection of sound. When sound reaches these walls, it is reflected in different directions or absorbed by multiple reflections. In this way This will ensure a better hearing effect.

Concert Hall:

The concert hall is a place for concerts and music-related activities. It is a place where people feel the charm of music. It usually consists of a music hall and a small theater, with elegant decoration and appropriate layout. There are many factors to consider in the design of a concert hall, including the pursuit of bright light and reasonable illumination. The world's famous concert halls include the Vienna Concertgebouw, the Sydney Opera House, the National Center for the Performing Arts of China, etc. At the same time, many concert halls are local symbols. Among the various expression elements of music and art, the most mentioned expression elements of synesthesia are those related to color. The phenomenon of visual-auditory synaesthesia is mainly manifested in aspects such as pitch and tonal color, timbre color and harmonic color. Tonal color is one of composers' most passionate topics. Research has found that the color perception of a bar may be related to the number of sharps and flats. In addition, the timbre of musical instruments is often described by people using words. For example, the oboe is green, the flute is silver or blue, the trumpet is golden, and the clarinet is rose. Sometimes chords are also combined with movement: augmented triads are expanded like a deep breath, while diminished triads are curled up. Therefore, whether the color selection inside the concert hall is correct or not is an important link in the entire concert hall design process. It is related to factors such as intimacy, warmth, and space, and will directly affect the subjective feelings of the audience.
