It is believed that similar devices existed before, though there are only records of their use from that century on. The basic operation of ear trumpets is described in antique books such as the one published by Jean Leurechon in 1624. These pieces were made of different materials, with exclusive and expensive designs made of gold, silver and diamonds. The last company that manufactured ear trumpets, F. Rein & Son of London, disappeared in 1963.
