How confident are you that the noise pollution in your lab isn’t reaching levels that could be interfering with the quality of your lab’s research—or worse, risking the health and well-being of your personnel?
Noise and, of course, its accompanying vibrations can result from conversation, the ever-present hum of lab equipment, or outside environmental factors (think of the landscaping crew running the lawn mower every Wednesday at 3pm).
All that noise can lend to a chaotic environment in which communication breaks down and instructions become harder to follow. High-level occupational noise leads to hearing loss and even low-level occupational noise has been linked to stress and cardiovascular disease.
In short, rising noise levels are a serious liability.
What Does Noise Reduction have to do with Lab Safety?
While the noise is doing a number on the people in your lab, vibration is compromising the integrity of your lab equipment. Your mass spectrometer, and the furniture that supports it, is slowly being shaken apart; tubes may begin to leak, cooling fans may start to break, and table joints become less stable.
The most ideal way to battle noise and vibration is to treat it at the source. Investing in dedicated lab furniture that’s designed specifically to minimize and contain noise is half the battle. But there are also soundproofing treatments you can incorporate into your lab design to help keep the equipment noise contained, and some of the hazardous side-effects at bay.
Basic Soundproofing Principles
Avoid air cavities – Trapped air resonates and causes the walls or sides of whatever material is trapping it to vibrate. It’s the same basic principle of most musical instruments; drums, guitars, wind instruments—vibrations are captured and manipulated within an opening to produce a desired sound. So, if you have walls, cabinets, nooks or crannies in your lab that are potential air traps, find a way to identify and insulate those cavities with foam or other materials designed to absorb vibration.
Enclosures and barriers – At the core, noise reduction is about preventing sound from penetrating one side of a wall or enclosure and transmitting through the material into an adjacent area. Walls and barriers act as shields which dampen noise. Some labs are built with soundproofing and noise enclosures in mind, but if yours isn’t one of them, you can help alleviate the transmission of noise and vibration by creating or installing walls and barriers around your noisy mass spectrometer and vacuum pumps, gas generators, compressors, freezers—you get the idea.
Damping – The more mass a wall has, the harder it is for sound to travel through it. You’ll want to make sure your walls are thick and dampened. There are several sources online that will help you do this yourself. Of course, you can hire companies to do some of this work for you, and that might be practical if you’re redesigning your current lab or investing in a new construction project.
Noise Reduction, Compliments of Dedicated Lab Furniture
Like every other task in your lab, you need the right equipment and tools to get the job done. Cutting a significant portion of the noise off at the source will help reduce the total ambient sound traveling throughout your lab. Quiet vacuum pump enclosures are specialized cabinets designed to reduce vacuum pump noise by approximately 75%.
Our lab benches and desks are also expertly built with noise-reduction in mind. IonBench uses patented calibrated dampening springs to remove 99% of vibration transfer.
Beyond that, any soundproofing materials or barriers are just icing on the cake.
If you’re in a position to decide what the best plan of action is to soundproof your lab, and aren’t entirely sure what the next steps are, get a hold of us. We can help you with a noise reduction system that’s best for your needs.
