  • Remarques

  • The Acousticon Model 28 carbon hearing aid was manufactured by the General Acoustic Company, which later became Dictograph Products, Inc. of New York, NY.

    Since the Model 28 came out around Acousticon's 25th anniversary in 1928, it was also called the "Silver Seal Symphonic" or "Silver Anniversary". In honor of this, the microphone and volume control were inlaid with a fancy pattern.

    The Model 28 was manufactured between 1928 and 1932. It replaced the Acousticon Model SRB.
