How Does Noise Pollution Impact Long-Term Focus?

Lately, I’ve noticed how the constant hum from lab equipment at work really tests my ability to stay focused for extended periods. It’s not loud or jarring, just this persistent background noise that seems to wear on my concentration over time. I’m curious if others have experienced something similar and what strategies you’ve found helpful for tuning out distractions like this. Does anyone have tips for maintaining mental clarity in noisy environments?
