Laboratories and R&D

Microelectronic fabrication facilities, nanotechnology and nanofabrication laboratories, R&D facilities, quality control rooms, clean rooms, biotechnology and pharmaceutical test facilities, medical and healthcare buildings, and hospitals are among the facilities that are extremely sensitive to excess noise/vibration. The reasons for high sensitivity to noise and vibration are operational performance on sub-micron scales, patients undergoing surgical operations, or accuracy and performance of machinery. In these situations, vibrations and noise are undesired that must be controlled to yield better results.

Internal Vibration Sources

These types of facilities often house more mechanical equipment than normal manufacturing operations. For example, vacuum chambers use large scale rotating equipment needed to maintain air pressure, exhaust, cooling, etc. These types of equipment are vibration-generating components that can cause a large variety of problems ranging from decreased production quality to destructive forces being applied to the structure.

Internal Noise Sources

Most settings are designed for human comfort and speech intelligibility. However, in some cases any type of acoustical disturbance is unacceptable. This is especially true in the nano scale regime with tools such as atomic force microscopy (AFM), tunneling electron microscopy (TEM), and others. In these situations, HVAC and exhaust systems are usually the primary sources of noise and air-borne disturbances.

Environmental Noise and Vibration Sources

Environmental noise from highways or rail traffic may be compounded by the dynamic characteristics of the site soil medium. Poor soil conditions may expose the facility to higher impact from adjacent rail and road activities/events. Noise and vibrations from construction sites and nearby factories and mining plants may also be a problem. Airport noise propagates throughout surrounding neighborhoods. Our team has experience in identifying, evaluating, and addressing the noise and vibration propagation paths at the root of these types of problems.

Consideration of Vibration and Noise in Facility Design and Layout

The vibration of these extremely complex facilities requires experience and understanding of sources of vibration and noise. This can be done through field measurements, theoretical and experimental knowledge of structural dynamics. Our abilities to employ both analytical and empirical tools to arrive at proper facility design are unparalleled.

At QRDC, we specialize in both implementation of our solutions in the initial facility design and retrofitting existing facilities to reduce noise and vibration. Please contact us for more information.
