Pauta de sonido: música que dibujar

Sonido:
Música, la pauta de sonido que se ha de ilustrar mediante un dibujo.

El ejemplo de la música es parte del entrenamiento auditivo con música.

Medios de pautas de sonido para representar sonidos en una pauta o dibujo. Los estudiantes escuchan la música y tienen que tratar de expresar los movimientos del sonido y los diferentes tonos de manera gráfica, por ejemplo, mediante una línea ondulada para música en curso.

Información e ideas:
Se puede efectuar el ejercicio en lecciones de música como parte del aprendizaje sobre música o en ejercicios de aquietamiento y concentración en el curso de una lección.

Pertinente para la enseñanza de:
Estructura y función de un órgano sensorial
Los sentidos descubren el medio ambiente
Juegos para practicar el uso de los sentidos

People can cause a noise with their voice, for example, to call out "Hello, I am over here".

Loud shouts can reach a level of 70 decibels. That is about as loud as when a car drives past about 10 metres away.

Information and ideas:
Recording to be identified by students.

Relevant for teaching:
Noise: causes, effect, protection
Noise consumption and leisure-time activities

Can you hear digital data?

Recording:
Is digital data audible?


A digital phone call (DSL, ISDN) is transmitted as an audio frequency. If you listen in to the transmission signal, though, all that you can hear is an incomprehensible twittering noise. This is because the signal is digitized and coded in binary form. At the beginning you will hear the dialing tone, a sequence of different pitches containing the call number in coded form. The subsequent twittering noise is then the digital call signal.

Information and ideas:
Students can carry out their own experiments with a classic analog modem with a monitor speaker which is a very good way to study the transmission of digital data in the audio frequency range. If you carry out the connection test with T-Online, for example, you can see what is happening and being transmitted at that moment in a text log displayed on the screen parallel to the audible sound.
