Not just toys

Unlike the typical toys he really dampens noise significantly and has since been used for all sounds: drill, blast, vacuum cleaners, loud look at construction sites, ... he has not endured well also childlike bending, is therefore stable. In my view, highly recommended.

Whether he really corresponds to the standard or reaches the specified dB value, of course, I can not measure. But if you hold the ans own ear, a really strong damping Aler noise is noticeable. In addition, a child is now working so well with no ear protection similar daily on jackhammer, which is probably rather the approach of such values ​​of OSH standards.
