The Foundation for the Deaf says toys that are too noisy could be damaging the health of children, and parents should consider that before buying them.
The organisation's spokesperson, Stewart Forsyth, says many toys exceed the recommended noise limits set for Australia and New Zealand.
For toys like rattles, that's 85 decibels. Tests have found that some toys are as loud as 110 decibels, he says, but they don't have to carry a warning label.
The Toy Distributors' Association chairperson, Dean Underwood, says the industry does follow the standards set, but parents should apply common sense and monitor their children's use of noisy items.
