The Ear, Hearing and Hearing Impairment: Effects of noise

Schematic diagram:
The graphic shows that - apart from physical effects - sound does not become noise until it reaches the brain.

Noise has effects on the physical and mental health of human beings. What the individual subjectively considers to be noise depends on a number of factors, for example the individual's own mood.

Information and ideas:
Can be used as introduction to topic "What are the effects of noise??.
Can also be used for illustration purposes: individual parts can be covered up (and then gradually uncovered in the course of the lesson).

Relevant for teaching:
Noise: causes, effect, protection

The Ear, Hearing and Hearing Impairment; ; Teaching unit: Personal health care for the ear: This is how I damage my sense of hearing

Interactive graphic (with audio):
What happens with my hearing or hearing ability if I listen to music which is too loud, for example, with earphones, or I listen to it for too long?

This example clearly shows that after two hours of listening to loud music, a person?s ability to hear is reduced significantly.

Information and ideas:
When it comes to drugs and alcohol, young people are often no longer receptive to good arguments. This is different when it comes to volume. Young people subject themselves to excessive volume usually without thinking about it. The result that can be tested on oneself that listening to loud music for just two hours leads to a clear deterioration in hearing does give them food for thought.

Relevant for teaching:
Noise: causes, effect, protection
Noise consumption and leisure-time activities
Senses discover the environment
Keeping the sense organs healthy

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.

Relevant for teaching:
Hearing defect/hearing impairment

Injuries to the ear through violence

Photo:
"Ouch!" Pulling at somebody's ears not only hurts, it can be dangerous and injure the ear both internally and externally!

Do not pull hard at somebody's ears or clip anyone round the ears because that can damage the sensitive ear.

Information and ideas:
A situation that can be observed in the school playground or at a children's playground. The photo can be used to start talking about the topic of how to protect the ears.

Possible questions:
What am I allowed to do to my ears?
What should I not do?
Why can a joke end up having serious consequences?

Relevant for teaching:
Hearing defects, hearing impairment
Personal health care
