In 2010, the composer Richard Einhorn suddenly lost most of his hearing. He could still write music, but wearing hearing aids made it frustrating to attend a public performance: The sound typically was blurred with static and ambient noise. Then he attended a musical at the Kennedy Center that used a “hearing loop” — a wire that beamed sound to the telecoils built into many hearing aids and cochlear implants. Einhorn was delighted with the result.

This weekend, he’s working with Baltimore Symphony Orchestra and the Hearing Loss Association of America to introduce other people to the same pleasure.

Most of the seats in Baltimore’s Joseph Meyerhoff Symphony Hall will be looped for performances Friday and Sunday of Einhorn’s 1995 composition “Voices of Light,” an oratorio that will accompany the classic silent film “The Passion of Joan of Arc.” HLAA members get a 20 percent discount on tickets and are invited to meet Einhorn at a reception after Friday’s 8 p.m. show.
