California Code, Business and Professions Code - BPC § 2538.12

A licensee may conduct hearing screenings at a health fair or similar event by the application of a binary puretone screening at a preset intensity level for the purpose of identifying the need for further hearing or medical evaluation.

Upon the conclusion of each hearing screening, the licensee shall present to the person whose hearing was screened a written statement containing the following provisions:

“Results of a hearing screening are not a medical evaluation of your ear nor a diagnosis of a hearing disorder but are only the identification of the need for further medical or hearing evaluation.”

A licensee conducting hearing screenings pursuant to this section shall not make or seek referrals for testing, fitting, or dispensing of hearing aids.
