Actually, a colleague who works for OSHA measured his infant's scream some years ago and noted that it was well within the range of hearing damage (if sustained). I don't recall the actual numbers but 140 dB would certainly be at that range. I remember thinking at the time that perhaps the reason parents respond to the infant (or child) screaming so quickly is more to spare themselves hearing damage than to tend to the needs of the fussy kid. It certainly is a good biological mechanism (for the kid)! Rebecca Mercuri mercuri(at)
