Noise at the workplace

Recording:
Collage of different sorts of noise at the workplace. Noisy machines at the workplace require protection against noise.

Noise is often equated with industry and hard work. There is considerable noise exposure on building sites or in factories where there are often noisy machines. There are regulations to avoid damage such as the wearing of ear protectors or the adoption of noise-reducing measures.

Information and ideas:
Recording to be identified by students or used to look at the topic of "Noise". Activity: Draw a machine which makes these noises!

Relevant for teaching:
Noises: causes, effect, protection
Noise consumption and leisure-time activities
Senses discover the environment

Ghosts howling

Sound:
Ghosts howling is a sound that is not encountered in reality but, nevertheless, we immediately recognize the sound.

Children like it when it is spooky! A ghost can rarely be seen but is often heard.

Information and ideas:
Recording to be identified by students or used for sound effects for a radio play/story.
Interesting for the subject of communication and also interesting for illustration purposes. It is not always the real sound that is important but what the person hearing it associates with it or how he interprets it.

Relevant for teaching:
Structure and function of a sensory organ
Senses discover the environment
Games to practise using the senses

The Ear, Hearing and Hearing Impairment: Drums

Recording:
A practising drummer is regarded as a source of noise, as a member of a band he supplies the rhythms that get people moving to the beat.

The rhythms which a drummer produces are an important part of a group and their sound.
Music can be produced by drums alone without other musical instruments.
It can reach levels of 100 decibels.

The Ear, Hearing and Hearing Impairment: With eyes blindfolded

Photo:
To illustrate the topic "Seeing with your ears?.

When the sense of sight is not working, another sense can replace the eyes. We pick up a lot of information about our environment from our ears and can thus, in part, at least, substitute the sense of sight.

Information and ideas:
For example, students can try out themselves on a listening walk whether they can guess where they are.

Relevant for teaching:
The human body
Structure and function of a sensory organ

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!

Information and ideas:
Supplementary to worksheets and transparencies.

Relevant for teaching:
Sound/acoustics: parameters
Vibrations and waves
Communication and understanding

The graphic shows the oscilloscope curve of the spoken sentence "It?s raining cats and dogs" and excerpts from the units from which speech is composed: sentence, word, phoneme.

Information and ideas:
Speech recognition and speech synthesis are very topical themes in the field of information and communication technology.

B2 Greenhouse effect in a drinking cup (answer sheet)

Answer sheet:
For the student experimentation instructions of the same name.

The answer sheet contains sample answers to all questions asked in the student experimentation instructions. In some cases, the answers are very short, often only in the form of key words. Depending on the learning objective, they can be augmented and enlarged upon with additional material from textbooks or Internet research.
Likewise, the answer sheet will be elaborate on the analyses for the individual subexperiments, but only in cases where experience shows that there could be difficulties.

You will find more detailed information in the related experimentation instructions "B2 Greenhouse effect in a drinking cup (student instructions)", which are available on the media portal of the Siemens Stiftung.
