HURTFUL TO SOME EARS! The sound created was made by a small 1 second beeping sound sound effect. The frequency was increased to 16,000 Hz and set to a wave amplitude of 0.01! This sound was tested on a group of ten subjects between the ages of 15-40 and was only heard by 3 of them. They were all under the age of 18. When played around small household dogs and cats it seems to get their attention but not send them running. Probably a good bet for a ringtone that you don't want your teachers to hear. Is being used in my companies new upcoming movie inspired by David Lynchs' "Eraser Head" to make our audience mad and make us unforgettable by them.
