🧠 Hearing Science & Presbycusis
💡 Presbycusis (Age-Related Hearing Loss): High-frequency hearing loss begins in the ear's cochlea. This is why adults over 25 often cannot hear the 17,000 Hz or 19,000 Hz mosquito tones.
💡 The Mosquito Tone: 19,000 Hz is famously used in anti-loitering devices because only teens and young adults can hear this high-frequency sound.
💡 Headphone Warning: Playing high-decibel sounds through earbuds can cause permanent cochlear damage. Keep your volume at 60%!
