The Sound Only Teenagers Hear

We lose the highest notes as we age

Some shops have played a buzz that sends teenagers away while most adults hear nothing. How can one sound reach only young ears?

You'll find out

  • How high your own ears can go
  • Where in the ear high notes live
  • Why the top notes fade with age

Why it matters

Every ear has a top note, and it creeps down over a lifetime. Knowing why helps you look after yours.
