Of interest to you may be the IEC document 108/244/CD, part of the proposed IEC 62368 hazard based standard likely to be published next year. It proposes limits of 118 dBA, up to 125 for handsets, 121 for inserted earphones provided with the product, 136 for less than 0.5s, 130 under fault conditions and 136 for less than 0.5s under fault conditions, measured using parts of IEEE 269. There are also voltage limits for audio sources. Check with George Tsitsopoulos at your company for the complete text.
