Very mild super powers

I found out today that a girl at work has an amazing affliction. She has incredible hearing.

We were at lunch and the sound of coins on a tray caused her to shudder. Then she admitted that she can hear really high pitched noises.

Whining computers and printers? She can hear them.

Ultrasonic pest repellent machines? She can hear them.

Dog whistles? She can hear them.

Electronic devices on standby? She can hear them.

Whales talking to each other? She can probably hear them.

Awesome!
