Beginning August 22, 2016, blenders, hair dryers, and vacuum cleaners are now required to display a noise label established by the National Institute of Metrology, Quality and Technology (INEMTRO). The label, to be placed on the product’s packaging, provides information to consumers on the device’s sound power in decibels and classifies the device using a number system from 1 (quietist) to 5 (loudest).
