Some of the toys were as noisy as a chainsaw or a lawnmower.
Among the toys tested were:
- Tonka Mighty Motorised Fire Truck
- Marvel Super Shield Captain America
- Whac-A-Mole Game
- Sesame Street Let's Rock Elmo
- Toy Story Buzz Lightyear Cosmic Blaster
Researchers said parents should hold toys closely and listen. If they hurt your ears, then they're probably too loud for your child.
