Loudness, or the intensity of sound, is measured in decibels. the sound level of a television is about 70 decibels, which is considered a safe hearing level. a food blender runs at 20 decibels higher than a tv, and a jet engine's decibel reading is 40 less than twice that of a blender. at this level, exposure can cause hearing loss. find the intensity of the sound of a jet engine.

Which detail from the passage best supports the author's assertion that listening to loud music can create hearing loss? i've listened to countless hours of music - vibrant music pouring into my ears from mp3 players, washing over me from car speakers, or blasting at me from gigantic speakers at concerts. experts say that noise-induced hearing loss can happen from hearing a very loud sound (120 decibels or higher) once, or from hearing a sound at 85 decibels or higher for an extended period of time. because of the hearing loss, i can't make out certain sounds, and that sometimes makes it hard for me to understand what is being said. or you may say, "but, julia, it's only 12.5% of all kids who have hearing problems due to excessively loud noise. this means that plenty of kids listen to loud music without any bad consequences."
