Agreed on constant tones. I have headphones that can block out the lawn equipment pretty good. The one neighbor has a service that comes and they're gone in 15 minutes. 3 guys with leaf blowers at the end for 90 seconds and the headphones make them sound like they're a few blocks away. The other neighbor is trigger happy and he likes to rev it up and down and my headphones can't keep up. I shut the windows and gnash my teeth for the 15 minutes it takes him to blow his yard.
