How loud is a ticking watch?
A ticking watch measures about 20 dB, roughly as loud as normal breathing. That sits well below the 85 dB level where hearing damage begins, so it carries no hearing-damage risk at any length of exposure. Sleep and concentration are a separate question: the WHO night guideline is 45 dB. Normal conversation runs about 60 dB for comparison.
