Piercing Sound
This is a loud, shrill, piercing whistle, almost painful in close proximity. At 110 decibels, this is just below a police siren (120 dbl), and a chain saw (115 dbl). Your gym teacher’s whistle was about 80-90 dbl. This seems about 10 dbl louder than a TOPS Knives Whistle, and the Fox 40 Micro is higher pitched/shriller than the TOPS. Fox 40 Micro makes an irritating noise, like nails on a blackboard, or your mother-in-law’s nagging.
