I used to work for a company that among many things refurbished actual train horns. If memory serves me correctly, they produce a minimum of 140 db of sound (160 db for the larger horns). We tested them inside a large (4' X 8' X 4') heavy wooden box lined with foam to absorb sound. There was a sound level meter installed to make sure that the horn met the minimum specification.
It was inside a large room inside of a huge warehouse. It was moderately loud up inside the offices at the opposite end of the building whenever they tested it. It was REALLY loud before they started using the box for testing.
With the kids today and us old farts dying out this is the type of work and repairs people can expect until we go through a renaissance of basic mechanician....
Somebody would literally be running for their life...
ReplyDeleteYou got that right.
DeleteWhat a joke of an installation!

Wouldn't want to be in that room during testing.
DeleteIt required double hearing protection, even using the box. Ear plugs and muffs.
