“The proposed output limit of 120 dB SPL is consistent with the standards used for consumer electronics products, but there is a significant difference between earbuds used to listen to music for short periods of time, and hearing aids that a person with mild-to-moderate hearing loss will wear for most of a day. Prolonged exposure to 120 dB amplification can, according to hearing and medical experts, place the user at risk for suffering increased hearing loss.
