Forklift or timer? My heart rate says both

Twice this week at 6:40 a.m., our 3‑minute dip test alarm and the forklift’s 85 dB beeper overlapped, and half the crew froze mid pH reading like mannequins. I’m swapping the timer to a 1 kHz chime and adding a red strobe at the test station to keep us compliant and my blood pressure optimized — any other low-cost fixes you’ve used that don’t confuse ears in a noisy room?
