Someone on this website mentioned an Alpine brand of earplugs that shut out background noise, but the website for the company mentions several types of earplugs, I’m not sure which one was recommended.
I was with an employer for 11 years. They remodeled the office to a more collaborative, open-concept design with high ceilings and very little carpet – no acoustics whatsoever. I lasted a year before I had to get another job. The constant noise caused so much anxiety, I was in tears daily because, as an accounting clerk, I couldn’t concentrate to analyze problems and had to stay well into the evening to finish my work or go to the office on my time on the weekends and it was no longer worth it. Took a huge cut in pay to switch companies, but grateful for the peace in which it resulted. The struggle is real.
