Assessment of Potential Noise-induced Hearing Loss with Commercial “Karaoke” Noise
A study was conducted in Korea to examine the degree of potential noise-induced hearing loss by commercial Karaoke noise. The two variables that are used in the experiment are noise source and the music type. The maximum sound pressure level was measured along with hearing threshold levels. Findings suggest that Karaoke facilities are a serious threat to noise-induced hearing loss and that hearing protection is encouraged for safety. Other strategic ideas are to create sound absorptive treatment in Karaoke rooms, setting a volume limit and have warning signs to alert people that hearing loss can possibly occur.

Estimating Adolescent Risk for Hearing Loss Based on Data From a Large School-Based Survey
A group of 1512 adolescents from Dutch secondary schools were questioned about their music-listening behavior to determine if they experienced symptoms of hearing loss after listening to loud music. The methods used for this study was a questionnaire along with average sound levels of music from music players, clubs, and pop concerts. As a result, about half of the adolescents exceeded the safety standard for noise exposure. Adolescents normally exceed the safety limit of noise exposure from listening to music.
