Ear Trumpets (Ear Horns)

Long Domed Ear Trumpet (Ear Horn)

This long domed ear trumpet has no manufacturer's marks on it. It was likely produced somewhere around 1890. A long domed ear trumpet is listed in the 1892 Down Bros. catalogue. There were three sizes listed ranging in price from 7 shillings & six pence to 12 shillings.

It is a true "London Dome" ear trumpet in that the sound tube extends inside the bell and makes a 90° turn so the end of the tube faces the top of the dome to catch the reflected sound from the parabolic-shaped dome.

This long domed ear trumpet measures 15˝" long and 5˝" in diameter. The dome is about 4" high. This ear trumpet weights 9.3 oz. It is made of tin painted black.

This ear trumpet was built in a similar style to those designed by Harriet Martineau (1802-1876). These ear trumpets were called Martineau Hearing Horns.

Notice the wire ring at the base of the long tube. Goldstein wrote, "A ring soldered to the base of the long tube allows the user to hook a finger through it for ease of holding."  Personally, I find using this ring makes it very uncomfortable to hold this ear trumpet.

This is the largest and most uncomfortable-looking ear tip of all the ear trumpets in the Museum, but it certainly seals the mouth of the ear canal!

Unlike most of the long ear trumpets, this one doesn't have a comfortable hard rubber ear tip.

This long domed ear trumpet comes apart to make it shorter for carrying and storing.

The long tube slides onto the dome piece.

After sliding the two pieces together as far as they go, you twist the ear tube so the hook is locked behind the flange so the two pieces cannot accidentally come apart. This is the only ear trumpet of which I know that has this cool feature.

While in the locked position you can still twist the ear tube to make it work for either the left or right ear.
