Project Background


Guangxi Baise Lingyun Gymnasium enjoys a good geographical location at the Hongxin District of Chennan Town. The Gymnasium is the first one in Lingyun County, which provides a whole new platform and brings new energy to Lingyun County’s public sports undertakings. It also provides good environment for the public sports exercise and competitive sports development, and contributes to improving people’s living quality, living environment and investment environment. Moreover, it also contributes greatly to economy construction, social development and social harmony.


The officerspaid great attention to the sound effect of the Gymnasium, thus were very cautious in selecting audio equipment. They finally chose HMAUDIO as the project contractor, considering HMAUDIO has already maintained good reputation and profound experience in the sound effect design for multi-function halls of police stations and hospitals, as well as HMAUDIO’s extensive practical experience and strength in the area of DSP audio R&D and reliable product quality.


Project Requirements

This project main task was to build a multi-function hall for the gymnasium. Our customer required the conference system should be natural and clear in sound effect, while the system should be stable, functioned perfectly and operated efficiently. Since the multi-function hall is not only used for large conferences, but also used for small size performance, thus except for the regular meeting sound amplification, the system should also contains adequate sound pressure level, as well as structured and coherent sound affect. It should also possesses full-time working capability to satisfy daily sound amplification with clear sound effect.
