Just How Noisy Are Toys?

Consider noise when choosing toys

Christmas is just around the corner so it is time to talk about those brightly wrapped presents under the tree – specifically, all the noisy children’s toys.  In fact, it may be best to leave Santa earplugs instead of cookies and milk- chances are his bag of goodies are filled with dangerously loud toys!

Let’s get the basics of noise down first.  Two aspects of noise need to be considered when examining the effects on hearing: the loudness (measured in dB or dBA) and exposure time (seconds, minutes, or hours).  The National Institute of Occupational Health and Safety states noise should be kept at or below 85 dBA for periods of 8 hours or longer.  For every 3 dBA increase in noise, the exposure time should be cut by half.  In general, the louder the noise, the shorter amount of time you should be exposed to it.  Nearby is a graph that shows the average levels of noise for various items or environments.

SHA has several recommendations for parents on how to reduce the effects of the noise.
• Press the buttons or rattle the toy in the store- if it sounds too loud, then it will be too loud for your child.
• Many toys also have a volume control- keep the volume on low at all times.
• Place masking or packing tape over the speaker- this greatly reduces the amount of noise emitted.
• Limit the amount of time the child plays with the noisy toy(s).

The Holidays are meant for sharing with loved ones and catching up with old friends.  It is important to keep in mind those “other” things that are important to us and our loved ones – especially the youngest who don’t know any better.
