Thanks for submitting your question. The name of the symbol you are looking for is the "International Symbol of Access for Hearing Loss". It is defined as a part of Americans with Disabilities Act (ADA) Title III Regulation 28 CFR Part 36 - Nondiscrimination on the basis of disability by public accommodations and in commercial facilities. Appendix A to part 36 - Standards for Accessible Design, section 4 of appendix A - Accessible Elements and Spaces: Scope and Technical Requirements, subsection 30.7 of section 4 - Symbols of Accessibility, part 4 of subsection 30.7 - Assistive Listening Devices.

Taken from the web page:
"(4) Assistive Listening Systems. In assembly areas where permanently installed assistive listening systems are required by 4.1.3(19)(b) the availability of such systems shall be identified with signage that includes the international symbol of access for hearing loss (Fig 43(d))."

Self Help for the Hard of Hearing (SHHH) has various signs/stickers featuring this symbol for purchase on their web site at www.hearingloss.org
Start at the home page and click on "Shop SHHH Online" then select the category Accessibility tools.
I would also assume that you can go to your local FastSigns (www.fastsigns.com)
or FedEx/Kinkos (www.fedex.com)and they should be able to produce a version of this sign for your use and/or may have ready made versions of this sign that meet ADA requirements.
