The House Ear Institute (HEI) http://www.hei.org is a non-profit 501(c)(3) organization, based in Los Angeles
Los Angeles, California
Los Angeles , with a population at the 2010 United States Census of 3,792,621, is the most populous city in California, USA and the second most populous in the United States, after New York City. It has an area of , and is located in Southern California...

, and dedicated to advancing hearing science through research and education to improve quality of life. Established in 1946 by Howard P. House

, M.D., as the Los Angeles Foundation of Otology, and later renamed for its founder, the House Ear Institute has been engaged in the scientific exploration of the auditory system from the ear canal to the cortex of the brain for over 62 years.

Institute scientists investigate hearing loss and ear disease at the cellular and molecular level, as well as the complex neurological interactions between the auditory system and the brain. They are also working to improve hearing aids and auditory implants, diagnostics, clinical treatments, and intervention methods. House researchers work with House Clinic physicians to integrate medicine and science through clinical and research trials that may directly benefit patients.

The Institute shares its knowledge with the scientific and medical communities as well as the general public through its education and outreach programs. House Clinic physicians volunteer their time to teach specialty courses in the House Ear Institute's professional education programs, attended by more than 22,000 doctors and research fellows since 1946. Outreach programs for the public serve people with hearing loss and related disorders as well as offer information about general hearing health and hearing conservation.

Today, the House Ear Institute's five-story facility accommodates more than 180 researchers and administrators within 22 departments. The recent growth of its research studies has led to the construction of the Institute's new Wallis Annenberg Research Center that is slated for completion in September 2008.

Since 1946, the House Ear Institute has led the way in defining the causes of hearing and balance disorders, improving medical/surgical procedures and prosthetic devices. The Institute's discoveries have helped millions of people receive successful treatments.

. The doctors at the House Ear Institute and Clinic have trained two to three Clinical Fellows a year in Otology Fellowship after completion of ENT residency. Through the Clinical Otology Fellowships, about one hundred fully trained otologists have carried the House techniques around the world and to other clinical training programs. Through one and two week surgical temporal bone courses, thousands of doctors from every continent have come to study ear surgery. To date, over 22,000 doctors have received training in their facilities.
