ideal for pump room enclosures and performs well as a barrier
across the spectrum, particularly at low frequencies.
• High-volume, low-velocity mechanical systems with duct
sock terminations, acoustic diffusers or plenum grilles are ideal
solutions for providing quiet air distribution while not compromising other environmental requirements.
• Incorporate absorptive and dampening architectural surfaces
in exposed labs to reduce resonance. Architectural examples may
range from research-inspired artwork printed on non-friable rigid
foam to magnetic sound-absorptive blankets used in place of tack
• Consider through-wall service connections over feed-through
conduits. Limiting openings in partitions maximizes the assembly’s sound transmission coefficient, and the design of through-wall connections may reduce vibration transmission between
periphery equipment and experiment.
CONSISTENCY AND THE IMPORTANCE OF A
Advancements in imaging resolution and the abundance of
nanoscale material samples require stable environments to provide
optimal equipment performance and precise measurements. The
parameters of these environments may include vibration, temperature, relative humidity, electromagnetic fields and quasi-static flux.
The consistency of each ensures the stability of working samples
