You can safely listen to music at 80 dB for up to 40 hours a week without harming your ears, a study conducted for the Commission concluded. Eighty dB is roughly the volume of road traffic."It's easy to push up the volume on your MP3 player to damagingly loud levels, especially on busy streets or public transport," Kuneva said, adding that young people especially "have no idea they can be putting their hearing at risk."The new standard default setting on devices won't prevent users from overriding the default settings and pumping up the volume, but there will be clear warnings so they know the risks they are taking, Kuneva said.The industry said it supported the move but it warned the Commission not to try to prescribe universal volume levels for all users. It urged the Commission and standardization bodies to match the wishes of users with safety considerations when they set the default level.Bridget Cosgrave, director general of the trade group Digital Europe, added that music players are only one part of the problem of hearing loss, but the industry would cooperate in the European initiative, "to best serve consumer interests" she said. Digital Europe called for global harmonization of the standards to be applied in Europe. "Unharmonised requirements would undermine credibility and confuse users, potentially exposing themselves to inappropriate volume of noise," the trade group said in a statement. And it warned the Commission against setting "overly stringent regulations", pointing out that this would drive sales of products to countries with more relaxed regulation. Kuneva warned firms that she won't tolerate their failure to observe the new standards. "Regardless how big the company, no matter how reputable, I will take action," the commissioner said.
