Reverberation Time (RT) is the most fundamental parameter in room acoustics, representing the time required for the average sound energy density to decay from its original value to one millionth of that value after the sound source has been interrupted/stopped, or the time required for the sound to decay by 60 dB after the source is stopped, indicating that the sound has reached a steady state within the room. This can be expressed as T60.
The Speech Transmission Index (STI) is a rapid and objective measurement method developed to determine the degree of intelligibility reduction in speech after transmission. It is used to assess the quality of speech communication through a transmission channel.

It is an estimation of MOS Scores Based on Deep Learning Methods. MOS (Mean Opinion Score) is a standard for evaluating speech quality by quantifying users' subjective perceptions, assessing the quality difference between the original speech and the voice after network transmission. MOS testing is used to survey and quantify user behavior in perceiving and receiving speech quality. Different users are surveyed to compare their subjective impressions of the original reference speech and the degraded speech transmitted over a wireless network.
Sound Pressure Level (SPL) is a physical quantity used to describe sound intensity, representing the strength of sound pressure generated when sound waves propagate through air.
Yousonic Technology Co., Ltd. is a technology and innovation company that specializes in building acoustics, advanced communication acoustics, and artificial intelligence. The company's positioning is to be the leader in intelligent building acoustics standardization and is dedicated to improving the acoustic experience in various building environments. Traditional building acoustics is given wings with the integration of artificial intelligence.
The company is registered in the Suzhou New District Science and Technology City, with its research and development team and office located in Zhongguancun, Beijing. All full-time and research interns at the company hold a master's degree or above and come from top universities such as the Chinese Academy of Sciences, Nanjing University, Peking University, and Beijing University of Science and Technology.
The main research and product directions of the company include: using deep learning to obtain key acoustic parameters of buildings; sound absorption modules, improved MPP sound absorption structures, sound absorption panels, and new polymer sound absorption materials; directional sound reinforcement arrays.
Polyimide-based absorbing material is a type of absorbing material that is lightweight, has excellent sound absorption performance, good thermal insulation properties, excellent fire resistance, water repellency, outstanding environmental performance, and no fiber or dust pollution. It is also easy to install.
Combining sound-absorbing structure with whiteboard functionality, it can serve the dual purpose of providing effective low-frequency sound absorption and functioning as a writable whiteboard. This combination is suitable for various settings such as classrooms, training rooms, conference rooms, and more.
