1612795439Code 6848 Ear trumpetTelescopic ear trumpet made of brass and bakelite, English manufacture from the 1930s. Very good condition. Length open 31 cm - 12.5 inches, closed 22.5 cm - 8.85 inches, membrane diameter 11.5 cm - 4.5 inches.

The principle of its operation is based on the reflection of sound on the internal walls, so that a greater amount of energy from the propagation of sound waves is concentrated on the eardrum membrane. In fact, the narrowest part is placed near the ear and the wider one collects sound waves.
