New study reveals baby sound machines may damage hearing

Parents who use one of those sleep noise machines to help their baby fall asleep could be doing more harm than good.

Researchers at the University of Toronto say infant sleep machines can reach volumes that could possibly lead to noise-induced hearing loss.

They found many machines exceed the recommended 50 decibels at the closest distance.

Researchers say they're concerned because the gadgets are sold with limited or no instructions for safe use.
