Here's a link to what Shure says about listening levels. It includes OSHA recommended limits on exposure to loud sounds. Tinnitus commences at 127dB. 130dB is the level reached at very loud rock concerts. 140dB levels can cause hearing loss no matter how short the time exposure. Nausea is experienced after only a few minutes listening that loud.
