The Ear, Hearing and Hearing Impairment; Teaching unit: From the drum to the eardrum: Resonance body piano

Photo:
Grand piano and piano are good examples of the great significance of resonance bodies with regard to volume and sound.

The frame and the air in the piano vibrate in resonance with the string that has just been struck. Whereas the more modern grand piano "fills" whole concert halls, its historical predecessor, the spinet, is just loud enough for the living-room. Apart from the volume the tone colour of the spinet is also much thinner. This comparison makes the importance of the resonance body very clear - both generally in the production of sound and specifically in music.

Information and ideas:
A practical example from the field of music shows how important the subjects of Physics and Acoustics are for the world of art and communication.

Entire ear section (b/w)

Unlabeled graphic:
Simple black and white cross-section of ear. For worksheets, printouts etc.

With the help of this graphic the most important functional areas of the ear and their significance in the hearing process can be explained.

Information and ideas:
The teacher can label the graphic together with the students on the computer screen or get the students to label it themselves either on a printout or at the computer screen.

Attention when cleaning ears: Cotton wool buds must not be pushed too far into the ear canal as this can injure the eardrum.

Information and ideas:
Use picture to start discussion on the topic of "Health care" and specifically "How to take care of ears".

Die Organe im Körper

Grafik, beschriftet:Abbildung der Organe im Körper.Organe erfüllen bestimmt Aufgaben in unserem Körper. Das Gehirn ist die "Schaltzentrale" des Körpers. Das Herz pumpt Blut durch die Adern in alle Teile unseres Körpers. In der Lunge wird der von allen Körperzellen benötigte Sauerstoff aufgenommen. Darm, Leber und Bauchspeicheldrüse verwerten die Nahrung.

Training of senses

Photo:
A girl is shaking a film container in order to identify the content of the container by means of the noise.

This photo shows a situation from a listening memory game. The game involves the ability to remember and recognize things.

Information and ideas:
This is how the game is played:
Different materials like sand, rice, dried peas, pebbles or stones, flour etc. are filled into empty film containers, two containers for each material. Now the players have to match the pairs by identifying the material inside the containers by shaking The whole game can be played with teams of two partners as well. Each player gets a film container and has to go round and compare the sounds made when the containers are shaken and thus find his or her partner.
(Tip: Label all the containers on the bottom,
for example with colored dots so that the pairs can be clearly recognized again.)

The singing wine glass

Photo:
Rubbing a wine glass can produce tones.

If you rub along the rim of a wineglass with a wet finger this produces a tone. As soon as the glass produces a tone, short-wave marginal waves appear in the liquid. The glass oscillates back and forth at those places at which the waves occur. Between them it is still. The oscillation of the glass is not only transferred to the liquid but also to the air and in this way reaches our ear in the form of a fine tone.

Information and ideas:
This experiment can be done easily in class - the class might even make a glass harmonica on their own?
Further information on this photo is available as information sheet on the media portal of the Siemens Stiftung.
