Ringing ears indicate damage even below the 85 dB threshold

Evidence

Hearing loss is insidious and permanent, and by the time it is measurable, it is too late. Therefore in order to protect hearing sensitivity and acuity, one must be proactive. The first strategy is to avoid exposure to excess noises. Although 85 dB(SPL) is taken as a damage threshold if the noise exposure causes ringing in the ears, especially if the ringing lasts longer than the length of exposure, damage may be occurring even if the sound level is less than 85 dB(SPL). — David M.
