Question

Electronic devices（装置）are changing the way people listen to music．But studies show the devices may be causing hearing loss in many people．Some experts say people may be playing them too loud and for too long．And experts say sound levels on these devices need to be set lower．

Researchers did a study with three hundred high school students and one thousand adults．They were asked about their use of portable music devices．Forty percent of students and adults said they set the sound levels at high on their players．But students were two times more likely to play the music at a very loud volume（音量）．More than half of the students said they would probably not limit their listening time．

The study found that more than half of the students and less than forty percent of the adults had at least one kind of hearing loss．Some reported difficulty hearing parts of a discussion between two people．Others said they had to raise volume controls on a television or radio to hear it better．And, some experienced ringing in their ears or other noises．

Hearing experts say part of the problem is the listening equipment people are using．They say large earphones that cover the whole ear are probably safer than the smaller ear buds（耳塞）that come with most music players．Hearting loss may not be obvious for years, however, once it happens, there is few chance of curing．About thirty million Americans have some hearing loss．One third of them．lost their hearing as a result of loud noises．

The American Speech—Language--Hearing Association is working with companies and government officials on setting rules for use of portable music devices．The group says the best way to protect your hearing is to _____________________, limit listening time and use earphones that block out foreign noises．
