This blog frequently talks about the importance of managing lab noise. We’ve covered decibels and health risks associated with lab-safety accidents because too much lab noise can mask warnings and cause miscommunication at critical moments. But how do you know if your lab is too noisy?
What Is Your Experience with Lab Noise?
Here are some questions to ask yourself when wondering if noise is a problem in your lab:
- When you leave the lab, do you sense humming or ringing in your ears?
- Do you have to shout to be heard by a colleague who’s at the next closest workstation?
- Do you experience temporary hearing loss when you leave the lab at the end of the day?
If you responded yes to any of these questions, then lab noise in your workplace may be a potential problem.
OSHA and NIOSH Workplace Noise Limits and Lab Safety
For all U.S. workers, OSHA has set standards and regulations for noise in the workplace. Exposure to noise should be kept below an equivalence level of 85 dBA for an entire eight-hour shift. For every sound level increase of 5 dBA over 90 dBA, the legal time limit is cut in half, which means you should only have to endure four hours in a 95-dBA work environment or two hours in a 100-dBA work environment.
Other organizations set stricter limits. The National Institute for Occupational Safety and Health (NIOSH) recommends less than fifteen minutes of exposure at the 85-dBA level per day and an exponential decrease in exposure time for every 3 dBA as opposed to 5 dBA.
If you are experiencing any of the lab-noise issues described above, you can take this to your supervisor and expect action. Ringing in the ears is unlikely to be taken as seriously as an objective measurement, but apps for that are now available.
Three Apps that Can Measure Lab Noise
While you might not have sophisticated instruments that measure noise in your lab, almost everyone has a smartphone these days. Here are three apps that measure lab-noise levels and provide a basic decibel reading, including statistics such as average-, low-, and peak-volume levels:
One thing to note is that standard smartphone microphones are not designed for precision measurements. If a basic reading concerns you, you may wish to invest in a sound-level meter to gather readings that will convince your supervisor of the seriousness of the situation. On the other hand, you can report your initial findings on your smartphone or tablet and suggest that your supervisor take it from there.
Dedicated Lab Furniture Reduces Lab Noise
One of the most efficient methods for reducing lab noise is installing dedicated lab furniture. Our IonBench MS sequesters MS roughing pumps and guarantees a 15-dBA reduction in noise levels.
