Space & Sound Challenge

This 180㎡ small precision testing laboratory is located in an industrial park on the outskirts of Munich, Germany, housing precision testing instruments, sample preparation areas and a small equipment room. Testing equipment, ventilation systems and centrifuges generate continuous broadband noise, which interferes with the accuracy of sensitive detection instruments and creates long-term noise exposure for lab technicians. The lab requires strict dust control, fire safety and cleanability standards, so acoustic materials must meet industrial hygiene requirements without generating particulate matter.

Tailored Acoustic Strategy

The full lab ceiling is fitted with high-density inorganic fiberglass acoustic ceiling tiles, with an NRC rating of 0.90–0.95, inherent Class A fire resistance compliant with EN 13501 standards. The interconnected porous structure efficiently absorbs full-spectrum reflected noise from equipment and airflow, while the dense hardened surface resists dust accumulation and supports regular wipe-down cleaning — critical for lab environments. Equipment room perimeters add partial perforated acoustic panels with mineral wool backing to assist with mid-low frequency equipment noise control. All materials are non-particulate and fiber-shedding free, meeting laboratory dust control requirements. The system requires minimal ongoing maintenance and maintains stable acoustic performance in temperature-fluctuating industrial environments.

On-Site Results

Ambient noise in the main testing area drops to within acceptable limits for precision instrument operation, and testing accuracy improves by reducing acoustic interference. Lab technicians report less fatigue and clearer verbal communication during experiments. The acoustic ceiling system withstands regular cleaning and dust control routines with no degradation in performance or appearance.
