Noise pollution has become a significant concern in modern society, particularly in places closely connected to daily life, such as offices, schools and hospitals. Acoustic ceilings play a vital role in improving indoor acoustics by absorbing or reducing noise, echoes, and reverberation, which enhances auditory comfort. They are an essential component of contemporary architectural acoustic design.
Office noise challenges
Open office environments are susceptible to echoing, which causes individuals to speak louder and consequently reduces speech clarity. There is a clear correlation between noise exposure and work efficiency. Studies indicate that after an interruption, employees take an average of 25 minutes to regain their original level of productivity, in addition to another eight minutes to regain focus, significantly hindering their productivity.

| Acoustic Environment Functional Areas | Daytime | Nighttime | Volumn | Recommended | ||
| Offie Space | Office Rooms | Category 1 | ≤55dB | ≤45dB | ＜1000m³ | 0.5-1.1s |
| Conference Rooms | Category 1 | ≤55dB | ≤45dB | ＜200m³ | 0.4-0.6s | |

High-quality acoustic products, such as acoustic ceilings, provide excellent acoustic benefits from three perspectives: activity, people, and space. This significantly improves employee productivity.
A diverse selection of products and mounting systems can adapt to various office environments. Furthermore, the elegant appearance and colorful design of these products add visual appeal to modern office spaces.
School noise challenges
A study indicates that the average noise level in Chinese classrooms is 65 dB. Primary and secondary school classrooms mainly use gypsum ceilings and hard-surface flooring, which contribute to varying noise levels and long reverberation times. This results in muffled and unclear sound. Statistics reveal that 69% of classrooms in various schools fail to meet regulatory requirements for reverberation time, while 57% do not meet the regulations for background noise levels.
Notional standards
| Location | Noise Level (Class A, dB) | RT60 Reverberation Time | ||||
| Acoustic Environment Functional Areas | Daytime | Nighttime | Volumn | Recommended | ||
| Education System | Classrooms | Category 1 | ≤55dB | ≤45dB | ＜200m³ | 0.4-0.6s |
| Gymnasium | Category 1 | ≤55dB | ≤45dB | ＜40000m³ | 1.2-1.4s | |
Ceilings effect
Acoustic ceilings can reduce room noise levels by 20% to 30% and decrease reverberation time to less than 1s. It can significantly lower indoor background noise, improve reverberation times, and enhance speech clarity. This allows for smoother and more efficient communication between teachers and students.
There is a wide range of product options and installation systems available that can adapt to the design needs of different school spaces. Additionally, elegant appearances and vibrant designs can enhance the aesthetic of school environments.
Hospital noise challenges
In Chinese hospitals, noise levels typically range from 50 to 70 dB, with peaks often reaching around 90 dB, which far exceeds international standards (≤50 dB during the day, ≤40 dB at night). On a global scale, hospital noise levels increase by an average of 0.4 dB per year. The primary contributors to this growing issue are traffic noise, medical equipment noise, and background noise in public areas.

| Acoustic Environment Functional Areas | Daytime | Nighttime | Volumn | Recommended | ||
| Healthcare System | Wards | Category 0 | ≤50dB | ≤40dB | ＜60m³ | 0.4s |

Ceilings effect
Specialized ceiling designs compliant with cleanliness and acoustic standards are essential in hospitals. These ceilings not only provide excellent sound absorption but are also moisture-resistant, mildew-resistant, and antibacterial.
High-quality acoustic performance can reduce actual hospital noise levels by 20 dB or more annually, significantly improving the indoor acoustic environment for both patients and medical staff.
Additionally, the flexible and diverse aesthetics of these ceilings create a modern medical environment that fosters a comfortable treatment space.
