Perforation of the eardrum

Labeled graphic:
Simplified illustration of a perforated eardrum.

A perforated eardrum can occur when foreign bodies, for example, instruments to clean the ears, are stuck in too far or when there are loud bangs near the ear.
Violent blows to the ear can also cause perforation.

Minor tears or perforations can heal up by themselves provided they get the proper treatment. In any case, a doctor should always be consulted!

Information and ideas:
Can be used for illustration purposes on the subject of "Ear diseases" either on transparencies or worksheets. Supposedly "harmless" minor problems can turn into serious damage to the ear.

Section of an ear shows the regions affected by middle ear inflammation.

In cases of inflammation of the middle ear (Otitis media) the mucous membrane of the tympanic cavity is inflamed.

Middle ear inflammation is usually caused by infections of the nasopharynx region which rise up into the tympanic cavity via the Eustachian tube.

Information and ideas:
This graphic is good for discussing possible complications (for example "mastoiditis?). The students should be made aware of how important it is to have these diseases properly treated and to make sure that they recover fully and properly.
Further information regarding inflammation of the middle ear in particular and diseases of the ear in general is available as information sheet on the media portal of the Siemens Stiftung.

;: Child with cap

Photo:
The best protection against colds and consequently against inflammation of the middle ear is to wear a cap in the winter which covers the ears.

Acute inflammation of the middle ear is one of the most frequent illnesses that children get. Acute means it starts suddenly, is very severe but is usually over quickly as well. This kind of inflammation occurs more during the winter. Children who suffer from it usually had a cold before.
While acute middle ear inflammation is very painful, it usually heals up and is forgotten quickly provided it is treated and observed properly.

Speech signal - individual word

Chart:
Screenshot of the oscillographic curve of the spoken word "dogs".

Speech sounds are fluctuating sound signals where the composition of frequencies changes all the time.
Aperiodical overlap periodical parts. Unlike noises, some of which have similar frequency curves, sound in speech is always the carrier of meaning or of messages sent out by the speaker. Other noises like smacking of lips, hissing, rhythms, basic pitch are typical of the individual (acoustic fingerprint) but not essential for the speech content!

Supplementary to worksheets and transparencies.
