Mosquito Tones

Tones above 17.4kHz are called "Mosquito" tones because typically only people under 25 can hear them. They are sometimes used to deter loitering in public spaces.

Presbycusis

Age-related hearing loss (Presbycusis) is the gradual loss of hearing in both ears as we age. Higher frequencies are usually the first to go.
