The Ear, Hearing and Hearing Impairment: Structure and function of the middle ear

Worksheet:
Structure and function of the middle ear.

The worksheet contains a cross section of the middle ear to be labeled. Additionally the functions of the middle ear must be described.

Information and ideas:
Motivating target-orientated task of revising what has already been learnt. Students must have understood the structure of the ear in order to be able to explain the path of the sound waves.
It is conceivable that the worksheet can be done together in class with the help of an overhead projector.

Relevant for teaching:
The human body
Structure and functions of a sensory organ
Reception of stimuli and transmission of information

Sound emission at the loudspeaker

Video (00:11 minutes):The visibly vibrating diaphragm in the loudspeaker obviously transmits its movement onto the air as sound waves.The principle of sound production and propagation as sound wave in the air can be recognized clearly with the example of the diaphragm of a loudspeaker. By the way, only the lowest-pitched tones are visible. With medium and high-pitched tones the movements of the diaphragm are so fast that they are invisible. Information and ideas:Suitable for demonstration purposes but also good for self-study on the part of the students. Idea: show the film without sound to begin with. The students should then guess what sort of noise/sound it might be.Relevant for teaching:Acoustic phenomenaSound/acoustics: parametersCommunication and understandingVibrations and waves

Guideline for the "Sound and types of sound" interactive whiteboard content

Guideline:
This document provides an overview of a possible scenario for using the content package for interactive whiteboards entitled "Sound and types of sound".


This guideline is intended for teachers. It presents all media of the content package and puts them in a meaningful didactic context using examples.

Siemens Stiftung

The Ear, Hearing and Hearing Impairment;: Sound propagation

Experimentation instructions:
Experiment cards for students on sound propagation, for example, make a string telephone or propagation of sound waves in a glass of water.

Sound needs a medium for propagation.

Information and ideas:
· Observe the safety information in the instructions as well as the applicable safety guidelines for your school and discuss it with your students.
· The experiments on sound propagation show the students that sound needs a medium to propagate. It becomes clear which materials conduct sound better and which materials slow the propagation down.
· The experiments can be done either in groups or as station training.

Relevant for teaching:
Acoustic phenomena
Sound/acoustics: parameters
Vibrations and waves

Water as wave model

Video (00:07 minutes, without sound):
A stone is thrown into calm water, ripples are formed.

The vibrations emitted by a source of sound can be compared with the ripples or waves created when a stone is thrown into calm water.
It is, however, directly comparable only as far as the concentric shape of propagation is concerned. Looked at in detail, the vibrations are in fact very different.

Information and ideas:
Students can do the experiment themselves on an excursion out of school.

Sound/acoustics: parameters

The Ear, Hearing and Hearing Impairment; Teaching unit: How I hear;: Experiments on bundling of sound

Experimentation instructions:
Experiment cards for students on bundling of sound, for example, megaphone or experiment with tube and funnel.

Instructions on how to conduct simple sound bundling experiments (ear trumpet, megaphone). In this way, the students learn about the phenomena through playing.
By the way: Sound can be bundled or funnelled. In the hearing process, this function is carried out by pinna and ear canal.

Information and ideas:
· Observe the safety information in the instructions as well as the applicable safety guidelines for your school and discuss it with your students.
· The experiments on the bundling of sound show the students that sound is often funnelled or bundled when it is transmitted or perceived.
· The experiments can be done either in groups or as station training.

Relevant for teaching:
Acoustic phenomena
Sound/acoustics: parameters
Vibrations and waves

The Ear, Hearing and Hearing Impairment;: Sound propagation experiments

Experimentation instructions:
Study of sound conductivity of different materials.

Sound can propagate in solid, liquid or gaseous bodies.
Glass, metal and wood, for example, are good conductors of sound.
Felt, cotton wool and polystyrene, for example, are bad conductors of sound.

Information and ideas:
To be done together with students in class or in group work.
