When I went back from my campus, I saw someone in public transportation. After she entered the public transportation, she sat down, opened her bag, took out a pair of earphones, and used it in both of her ears. Several second later, she enjoyed music.

A spokesman said: "RNID has been concerned for some time that many people are turning up the volume on their personal stereos to levels that could create hearing loss in the long term." Graham Frost, Ketua British Society of Audiology menyebutkan, resiko kerusakan pendengaran meningkat seiring dengan level kebisingan dan durasi penggunaan pemutar musik portabel. Menurut dia, perlu waktu bulanan atau tahunan hingga efeknya terasa kepada individu. Graham Frost, chairman of the British Society of Audiology, said the risk of damage increased with noise level and duration of use of personal music systems. He said it could take months or years for that become apparent to the individual. Kesimpulan, sebaiknya jangan menyetel musik hingga volume suara maksimal dan terlalu lama (beri waktu istirahat untuk telinga). So, don't listen to music to maximum sound volume and too long (give breaks for your ears).
