Reverberation in home theater

Another problem with room acoustics is the choice of optimal reverberation time. The reverberation time is affected by the area, shape, and materials used in the walls of the room, as well as other items placed indoors. We usually refer to a room with a longer reverberation time as an "active" room, and a room with a shorter reverberation time as a "silent" room. Because the sound effects of the theater and the venue are only related to the reverberation time of the room; the sound effects of the studio and studio are not only related to the reverberation time of the room, but also related to the reverberation time of the room where the audience is located. Therefore, the reverberation time of the studio and studio should be different from the reverberation time of the theater and venue.

Reverberation in studios and studios is usually done in two ways: one is natural long reverberation and the other is strong absorption of short reverberation.

For the studio and studio of natural reverberation, there is no need to add artificial delay and reverberation when making the program. However, since the programs produced in such rooms will be played in the listener's room through the audio equipment, the actual effect should also take into account the reverberation effect of the audience room. In general, the reverberation studio and studio of natural reverberation should be smaller than the theater and venue. Due to the different content of the recording or broadcasting, the reverberation time for the language and the room for music should also be different. The room used for language reverberation time is slightly smaller to ensure its clarity. The natural reverberation studio is mainly used for programs that have a natural sound effect, such as news programs, dialogues, and other language programs or traditional programs such as symphony and chamber music.

The short reverb studio and studio have short, flat reverb characteristics. The reverberation time is usually between 0.2 s and 0.8 s. Due to the short reverberation time, the sound is very “dry”, so you must add artificial reverb when you are making a program to get better sound and different artistic effects. Due to the development of artificial reverberation technology, the sound effect of the program is better by using a short reverberation and then adding different reverberation effects as needed. However, in the process of recording, because the sound is more "dry", it may have an impact on the artist's artistic level and the recording of the recording personnel.
