I'm of a similar age and couldnt hear it but strangely after a trip to the ENT specialist for my allergies (and some kick-butt meds) I can hear it.hey its fun to mess with. i am 39 so cannot hear it and when my 11 yr old came in i asked her if she can hear it and turned the volume on my speakers up loud and she ran out the room complaining her teeth are rattling. ha ha
