Musical intervals

Principle

The frequency ratio of two tones is called an interval. These intervals have special names in music. As a result, the experiment can be more easily understood by students, if the terms are known from music class, at any case (at the very least) they should know the C-major ...

Efecto Doppler acústico con contador digital

Principle

If an emitter of sound or a detector is set into motion relative to the medium of propagation, the frequency of the waves that are emitted or detected is shifted due to the Doppler effect.

Benefits

  • Easy frequency setting thanks to digital function generator
  • Intuitive ...

Generación de ondas sonoras

Principle

Sounds are generated by oscillations. The sound volume is influenced by their relative amplitude, while the sound pitch depends on their frequency. This relationship is examined based on three examples: oscillating ruler, tuning fork, string of a ...

Propagación del sonido en el aire

Principle

This experiment demonstrates, particularly clearly, the propagation of sound waves in air and, thereby, the working principle of the eardrum that is caused to oscillate by pressure waves. The movement of the membrane is transferred to the neighbouring air molecules, which in turn ...

Propagación del sonido en cuerpos sólidos

Principle

The transmission (or conduction) of sound through a solid body means: One end of the solid body is caused to oscillate (e.g. by placing a tuning fork on it). This oscillation propagates through the solid body to the other end of the solid body. The transmission through the solid ...

Propagación del sonido en agua

Principle

The aim of this experiment is to enable the students to find out that sound can also propagate in other media, e.g. liquids. For this purpose, they study the propagation of the sound of a tuning fork in a tube that can be filled with air or water. For comparison, the sound ...

El sonido como una onda sinusoidal

Principle

The aim of this experiment is to familiarise the students with the "measure Acoustics" software. First, the students record the sounds of two tuning forks with a microphone. Then, they analyse the frequency spectrum and the course of the amplitude of the recorded signal over ...

Sonido y ruido

Principle

Oscillations can be transferred through a medium (e.g. air or wood) in the form of sound waves. An oscillation with exactly one oscillation frequency is called harmonic oscillation or pure oscillation. In the amplitude-time-diagram, such an oscillation corresponds to a sine ...

Umbral inferior y superior de audición

Principle

The human ear registers deep and high sounds as well as faint and loud sounds. Are there limits or can we hear any kind of high and deep sounds? In this experiment, the students learn that the human ear can perceive sound only within a limited frequency range. For this purpose, ...

Audición direccional

Principle

The human sense of hearing is not only used to perceive sound, it even enables us to localise the direction from which we hear sound signals. On the horizontal plane of orientation (left/right, front/back) as well as on the vertical plane of orientation (top/bottom, front/back), ...

Visualización de la vibración de un diapasón

Principle

In this experiment, the students visualise the oscillations of tuning forks by plotting the oscillations of a pen-equipped tuning fork on a sheet of paper. They see that the sine curve is the course of an oscillation over time, and they compare the frequencies and amplitudes of ...

Batimiento acústico

Principle

If several sound signals reach our ears simultaneously, these signals superpose, thus forming a resulting signal. If the individual signals all have the same frequency, the resulting signal can also be heard with this frequency. The volume, however, varies. If one hears two sound ...
